Plate Heat Exchanger A plate type heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids. This has a major advantage over a conventional heat system in that the fluids are exposed to a much larger surface area because the fluids spread out over the plates. This facilitates the transfer of heat, and greatly increases the speed of the temperature change. It is not as common to see plate heat exchangers because they need well-sealed gaskets to prevent the fluids from escaping, although modern manufacturing processes have made them feasible. Plate Frame Heat Exchanger Application Plate Frame Heat Exchanger Cleaning Plate and Frame Heat Exchangers Animation Plate and Frame Heat Exchanger Approach Plate finned type Heat Exchanger Brazed Plate Heat Exchangers Plate Heat Exchanger Design The concept behind a plate heat exchanger is the use of pipes or other containment vessels to heat or cool one fluid by transferring heat between it and another fluid. In most cases, the exchanger consists of a coiled pipe containing one fluid that passes through a chamber containing another fluid. The walls of the pipe are usually made of metal, or another substance with a high thermal conductivity, to facilitate the interchange, whereas the outer casing of the larger chamber is made of a plastic or coated with thermal insulation, to discourage heat from escaping from the exchanger. The plate heat system (PHE) s was invented by Dr Richard Seligman in 1923 and revolutionized methods of indirect heating and cooling of fluids. Plate exchanger one is composed of multiple, thin, slightly-separated plates that have very large surface areas and fluid flow passages for heat transfer. This stacked-plate arrangement can be more effective, in a given space, than the shell and tube heat system. Advances in gasket and brazing technology have made the plate type heat system increasingly practical. In HVAC applications, large exchangers of this type are called plate-and-frame; when used in open loops, these heat system are normally of the gasket type to allow periodic disassembly, cleaning, and inspection. There are many types of permanently-bonded plate heat system, such as dip-brazed and vacuum-brazed plate varieties, and they are often specified for closed-loop applications such as refrigeration.   Plate heat systems also differ in the types of plates that are used, and in the configurations of those plates. Some plates may be stamped with "chevron" or other patterns, where others may have machined fins and/or grooves. Liquid foods such as milk, fruit juices, beers, wines, and liquid eggs are pasteurized using plate-type. Wine and fruit juices are normally deaerated prior to pasteurization in order to remove oxygen and minimize oxidative deterioration of the products. Plate Type heat exchanger consist of a large number of thin, vertical steel plates that are clamped together in a frame. So it may called as Plate and Frame. We manufacture Plate Heat Exchanger that are used in dairy, pharma and biotechnology, beverages, brewery, chemical and power sectors.

The hydraulic oil coolers designed by us are used extensively in power packs, presses, dredgers, plastics injection equipment and a number of other hydraulic systems.   Oil cooler can be connected to through hoses to the high-performance blocks by removing the plugs above the oil filter pad. It also contributes to lowering the engine-temperature. Of the three engine cooling systems (air, water, and oil), oil cooling is the most promising for getting big cooling gains with relatively little effort. It is necessary to keep the temperature of the oil, needed for the functioning of the engine and its subsystems, under control. Too high temperatures lead to a rapid degradation of the oil's lubrication characteristics with the risk of damaging mechanical parts. They may be designed to exchange heat between oil and air rather than oil and the coolant in the engine cooling circuit. The latter involves simplified oil circuits and low costs if compared to the oil-air solutions, which offer higher performances and do not imply an additional thermal load for the radiator.   Hydraulic Oil Coolers are used in variety of industries for desired applications. From standard to highly specialized, these units come in a full range of sizes and materials. These units are usually specified as floating head (TEMA type "W") with O-Ring and weep hole for early leak detection.

We offer marine heat exchangers, Mercruiser heat exchangers, marine water pumps and other marine cooling systems parts. We only can assist you in determining the best all around product for your particular application.  Marine heat system are the most common way to cool a boat's engine, using the lake, river or ocean water in which the boat floats. Since this water may be corrosive the engine may be cooled by a sealed mixture of distilled water and antifreeze. Heat from the water-antifreeze mixture is then transferred to the ocean (or lake or river) water which flows into a heat system. The water-antifreeze mixture runs through the heat exchanger dumping heat, but remaining separate from corrosive salts and chemicals found in the water the boat is floating in. If the ocean water eventually corrodes and ruins the heat system it can be replaced at a fraction of the cost of replacing the engine.   To protect the marine heat exchanger from corrosive salts, a sacrificial zinc anode is screwed into the heat exchanger. This anode must be periodically replaced as part of regular maintenance.   Because the water the boat floats in may be contaminated with floating particles such as wood or styrofoam balls the well designed boat will have a filter (often stainless steel mesh) to remove these particles before they are moved toward the heat exchanger. This filter must be periodically cleaned or else the flow of water to the heat exchanger will become obstructed and the engine will overheat.   Ocean water is caused to flow through the heat exchanger by an impeller, often made of rubber and looking like a paddle wheel. Impellers commonly fail by having their paddles fall off and when this happens the engine will overheat unless promptly shut off. Many marine engines using heat exchangers have a grease reservoir for the impeller. In such cases a screw is often made part of the reservoir and is turned a small amount periodically, such as once a month, to apply a bit of grease to the rubber impeller to reduce friction and prolong its life.   A consequence of using a heat exchanger on an in-hull marine engine is that there must be a thru-hull opening below the waterline to admit the ocean water to the marine heat exchanger. Most boats with this arrangement have a valve which closes this hole when the boat is unattended so that a leak in the cooling system will not cause the boat to fill with water and eventually sink.   There are three methods employed for water-cooled marine petrol and diesel engines: direct, heat exchanger and keel cooling. Direct cooling of the cylinders and heads by seawater is unsatisfactory, because the engine – which was probably originally designed for radiator cooling – will run too cold and the sea-water will eventually ruin the cylinder block and heads. Our cooler is suitable for small boats operating in shallow weedy water, but the need for pipe work external to the hull is a severe limitation. Heat exchanger cooling is the most common method, the seawater being isolated in components which can be designed to withstand its corrosive affect. The closed fresh-water circuit can be thermostatically controlled so that the engine operates at its design temperature. Our heat exchangers are high-quality products incorporating both the best materials and the latest technical features. The tube stack is fully floating, thus minimizing thermal stresses, and it can easily be removed should cleaning be necessary. Our heat exchanger header tanks prevent aeration of the engine water circuit which must be designed so that the system is self-venting on initial filling.It is usual for all the components in the seawater circuit to be in series, the gearbox-oil and engine-oil coolers being on the suction side of the sea-water pump and the heat exchanger and any sea-water-cooled exhaust manifolds being on the discharge side. In the case of turbocharged engines the charge air cooler should receive the sea-water first so that the lowest possible air temperature is obtained. The sea-water outlet from the heat exchanger should be from the end cover equipped with the upper connection, this ensures that the tube stack is always full of water. The gearbox cooler size will depend on the type of transmission used, but it will usually be a size smaller than the engine-oil cooler. If preferred, the oil coolers can be fresh-water-cooled; these will need to be larger owing to the higher water temperature but need not be suitable for sea-water and can be taken from our leaflet ENGINE AND TRANSMISSION OIL COOLERS.   A water-jacketed exhaust manifold is necessary on marine engines to reduce the temperature of the engine-room air space and the exhaust pipe. If the exhaust manifold is in the sea-water circuit it should be installed with the sea-water inlet at the back and the outlet at the front on the top to ensure that it operates completely full of sea-water. If the manifold is in the fresh-water circuit a small by-pass hole must be provided in the thermostat to ensure that some water is circulating through the manifold at ail times.   Our development is to combine a water jacketed exhaust manifold with the heat exchanger and header tank. This arrangement is particularly suitable for small series-produced engines; the manifold is cooled by fresh water and as a result a keel-cooled engine can be made by omitting the heat exchanger tube stack and the sea-water pump. On installation the fresh-water outlet from the manifold would be connected to the keel pipes and the return taken back to the engine fresh-water pump. Heat exchanger/manifold assemblies are heavier than ordinary marine manifolds and must therefore be supported on the underside using the fixing lugs provided.   When automotive engines are being converted for marine use the existing centrifugal-type pump should be retained for the fresh-water circuit and an additional pump fitted for the sea-water circuit. The sea water pipe bore should be chosen so that the velocity does not exceed 2 m/sec on the suction side and 3 m/sec on the discharge side of the pump. If the engine is being used to drive auxiliary equipment in a ship and the sea water supply is taken from the ship's main, ensure that the recommended flow rate cannot be exceeded.

  The flue gas system consists of two air heaters.

Calorifier is a term used to describe an extensive range of industrial and commercial hot water heaters. High performance tubular heat exchangers ensure Heat Transfer Equipments calorifiers offer the most flexible and economic solution to provide your hot water heating requirements. Heat Transfer Equipments heat exchangers utilize a range of primary heating systems.   Primary Heating Systems   LTHW (maximum temperatures of 100°C)   Low temperature hot water is the most common means of heating. Flows are usually based on a temperature drop of 11°C (from 82–71°C).   MTHW (100°C–120°C)   Medium temperature hot water systems are generally designed on a temperature drop of 30°C (from 120–90°C).   HTHW (temperatures above 120°C)   High temperature hot water systems are generally designed on a temperature drop of 40°C (from 150–110°C). Another important factor in the selection of primary water heating systems is the working pressure. Where the primary working pressure is greater than the shell design pressure the calorifier must be fitted with a bursting disc sized in accordance with the requirements of BS 853. Primary water pressure drops are generally not greater than 25 kPa. With HTHW Systems we recommend the use of flanged connections rather than screwed joints.   Steam   Steam is an ideal medium for water heating. Tubular heat exchangers can be designed to accommodate a wide range of pressures, although most users prefer to have calorifiers operating with pressures below 10 Bar g. Superheat can be accommodated and the degree of superheat should always be stated at the enquiry stage.   Condensate   Condensate tubular heat exchangers can be used to accommodate flash steam and subcool condensate. This harnesses the available heat which would otherwise be discharged from a traditional two pass tubular heat exchanger.   Heat Transfer Oil   Thermal oils have the benefit of high temperature combined with low operating pressures. Tubular heat exchangers are generally manufactured from cupro-nickel or stainless steel, depending on oil type.   Refrigerant   Generally only superheat is taken from systems although condensing units are available. Tubular heat exchangers are designed with double tube sheets incorporating a tell tale leak path. This reduces the risk from cross contamination between the secondary and primary sides.   Waste Heat   Storage calorifiers are a useful means of recovering waste heat from a variety of liquids or vapours and Heat Transfer Equipments offer a special design service for this purpose. Where the temperature or quantity of waste heat is insufficient for the desired output, supplementary heating can be incorporated into the calorifier to boost the storage temperature. The calorifier should be sized to absorb the maximum quantity of waste heat during the time it is available.   Water Hardness   Where it is required to heat water with a high degree of hardness, special precautions should be taken. This is especially true where high primary temperatures are encountered.   Calorifier Codes of Practice   BS 853 BS 6700 BS 5500 Commercial Calorifiers   Shell Materials   Copper Shells Stainless Steel Galvanised Steel Shells Duplex Cupro Nickel   Heat Exchanger Types   U-Tube Battery = Calorifier   This is the most common type of heat exchanger used in calorifier manufacturing. High efficiency tubes unaffected by thermal expansion provide extremely high levels of reliability. To ensure a high heat transfer capacity a wide range of multi-pass exchangers are available. Standard bundle arrangements are manufactured from 20mm tube although other diameters are used depending upon the duty requirement. Finned and plain tube options enable Heat Transfer Equipments to offer economic solutions to meet the most demanding duties.   Tubes are generally expanded into the tube plates and do not require sealing gaskets or ferrules. For high pressures and temperatures doubled grooved tube plates are offered. For tube bundles with straight lengths greater than 1250mm support baffles are fitted as standard. In order to ease disassembly batteries greater than 380 mm in diameter are fitted with a tapped hole to accept a lifting eye. In addition runner wheels, collar bolts and starting screws can be supplied. Tubes are available in copper, stainless steel,90/10 and 70/30 Cu-Ni.   Double Tube Heaters = Indirect Cylinder   Double tube heaters have replaced annular heaters. Whilst retaining low primary pressure drops and double sided heating surfaces, double tube heaters are of a much stronger construction. The heater is manufactured from pairs of concentric copper tubes and the primary water circulates through the annular spaces with collection headers at the top and bottom of the assembly.   By varying the length and number of tubes a wide range of heating surfaces can be fitted using standard components to construct the different headers. The secondary water is heated by natural convection with an added boost to the water passing the inner tube. The overall heat transfer rate is considerably greater than that achieved by a single annular heater and recovery rates in the order of 20 minutes can be achieved. Double tube heaters are generally used for low pressure applications where the removal of the heater is not required.   Copper Coil   Generally produced from a single tube formed into a helical coil and can operate at a greater pressure than a double tube exchangers. Unfortunately as the cylinder size increases the length of heating coil becomes disproportionately greater and this heater is therefore only practical for moderate size cylinders. The single coil is particularly useful for small flow rates with a large temperature drop such as those found in waste heat recovery and solar heating installations. Double coils are available for low pressure drop applications. Coils are able to withstand high working pressures. They can be safely used for high temperature water systems operating up to 200°C and in small cylinders for high pressure steam applications   Plate Heat Exchangers   Plate Heat Exchangers are compact and assembled from pressed stainless steel plates. Standard material for plates is 316L stainless steel. The plates are held in the exchanger by two methods, brazed and gasketted.   In brazed exchangers the stainless steel plates are copper brazed together to form a very compact and economic design suitable for pressure and temperature limitations 30 Bar g, 185°C. Gasketted plate exchangers use a gasket to seal the plate gap.   The gasket is glued to the plate. The plates can be easily removed for cleaning or maintenance. Maximum design pressure and temperature is dependent upon the frame rating, plate thickness and type of gasket selected. The plate exchanger offers the user several advantages.   In areas where maintenance space for 'U' tube withdrawal is limited then a plate heat exchanger offers a practical alternative. A plate heat exchanger can be serviced without any special tools or requiring heavy lifting tackle. If at a later date the design duty has increased then the plate pack can be easily extended by the addition of plates to increase the output for gasketted unit or replaced by a brazed unit with a larger plate pack. U-tube batteries, double tube and coil heaters rely on hot water convection currents to distribute the hot water within the storage volume. Plate heat exchangers will require a pump to circulate water from the storage volume and through the exchanger. A plate heat exchanger coupled with a pump on the cylinder side can offer an economic high output calorifier.

A plate type heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids. This has a major advantage over a conventional heat exchanger in that the fluids are exposed to a much larger surface area because the fluids spread out over the plates. This facilitates the transfer of heat, and greatly increases the speed of the temperature change. It is not as common to see plate heat exchangers because they need well-sealed gaskets to prevent the fluids from escaping, although modern manufacturing processes have made them feasible.   The concept behind a heat exchanger is the use of pipes or other containment vessels to heat or cool one fluid by transferring heat between it and another fluid. In most cases, the exchanger consists of a coiled pipe containing one fluid that passes through a chamber containing another fluid. The walls of the pipe are usually made of metal, or another substance with a high thermal conductivity, to facilitate the interchange, whereas the outer casing of the larger chamber is made of a plastic or coated with thermal insulation, to discourage heat from escaping from the exchanger. The plate heat exchanger (PHE) was invented by Dr Richard Seligman in 1923 and revolutionized methods of indirect heating and cooling of fluids. Brazed Plate Heat Exchangers Applications   Domestic water heating Hydraulic oil cooling Hydronic heating and cooling Snow melt systems Outdoor wood boilers, stoves, furnaces Radiant floor heating Beer and wort chilling and other water to water and liquid to liquid heat transfer applications Plate type heat exchanger one is composed of multiple, thin, slightly-separated plates that have very large surface areas and fluid flow passages for heat transfer. This stacked-plate arrangement can be more effective, in a given space, than the shell and tube heat exchanger. Advances in gasket and brazing technology have made the plate-type heat exchanger increasingly practical. In HVAC applications, large heat exchangers of this type are called plate-and-frame; when used in open loops, these heat exchangers are normally of the gasket type to allow periodic disassembly, cleaning, and inspection. There are many types of permanently-bonded plate heat exchangers, such as dip-brazed and vacuum-brazed plate varieties, and they are often specified for closed-loop applications such as refrigeration. Plate heat exchangers also differ in the types of plates that are used, and in the configurations of those plates. Some plates may be stamped with "chevron" or other patterns, where others may have machined fins and/or grooves. Liquid foods such as milk, fruit juices, beers, wines, and liquid eggs are pasteurized using plate-type heat exchangers. Wine and fruit juices are normally deaerated prior to pasteurization in order to remove oxygen and minimize oxidative deterioration of the products. Plate-type heat exchangers consist of a large number of thin, vertical steel plates that are clamped together in a frame. We manufacture plate heat exchanger that are used in dairy, pharma and biotechnology, beverages, brewery, chemical and power sectors. PHE plates are available in MOC AISI 304, AISI 316, AISI 316L, Titanium, Hast alloy, Monel in range thickness from 0.5mm to 0.9mm. It is suitable for handling fluid from 100 LPH to 3.5 Million LPH..

This type of Heat Exchangers are Specially used in Large Quantity cooling Requirements. We are main Suppliers Air cooled Heat Exchanger for Oil Refineries and Process Fluid Cooling. The most economical and most common style air cooler, the forced draft ACHE, uses axial fans to force air across the fin tube bundle. The fans are positioned below the bundle thus not exposing the mechanical sections to the hot exhaust airflow. The forced draft air cooler also simplifies future plant expansion by providing direct access to bundle for replacement. Structural disassembly is not required. The second most economical and most common style air cooler is the induced draft ACHE. This design uses axial fans to pull air across the fin tube bundle. The fans are positioned above the bundle thus offering greater control of the process fluid and bundle protection due to the additional structure. Lower noise levels at grade are another benefit. The induced draft air cooler does require some structural disassembly if bundle replacement is required.
