the vacuum impregnation plants can be designed as per clients’ requirements and is provided with the following specifications.   impregnation cycle   it is designed as per the schematic diagram attached and is used for varnish impregnation to be carried out in following steps: pre-heating the jobs in either impregnation chamber or oven. evacuation of impregnation chamber (after putting the jobs) to make the voids in the jobs clear and drying of jobs for specific time & required temperature / vacuum. induction of impregnant (varnish) in the impregnation chamber from impregnant tank to submerge the jobs in it. pressurize the impregnation chamber with dry air or nitrogen to fill the voids with impregnant. return the varnish to impregnant tank. evacuate the impregnation chamber and cure the jobs either in impregnation chamber or in oven for specific time.   impregnation chamber specifications : working volume: 100 ltrs to 5000 ltrs. Constructed from m.s. Plates, bars, structural etc. working pressure: @ 4 kg/ cm2 & vacuum: as per process requirement. lid opening: screw davit type for quick opening & closing. chamber dimensions: as per job size and quantity added provisions are oil heating / cooling jacket, quick clamping bolts, stirrer, neoprene gaskets, sight glass, illuminating lamp, pressure safety valve, vacuum & pressure gauge

Our Vacuum Drying Autoclaves are designed and manufactured as per the specifications provided by our clients. We have the capability to manufacture high performance autoclaves which increase the efficiency and performance of any plant. This equipment comprises a vacuum autoclave in which a cylinder containing a piston is situated at one end and can be closed at the end by a hollow piston containing a condenser casing. The cylinder is evacuated through a port and the piston is lowered to close the port immediately an injection valve is opened to fill the cylinder with an impregnating substance. When the injection valve is shut the piston slowly presses the impregnant out through the neck of the condenser casing. The pressure is increased till the ejection valve opens. A blast of gas cleans the cylinder to remove any remaining impregnant.

We manufacture Oil filtration plants with varying capacities ranging from500 LPH to 10000 LPH. These plants are available as single stage and double stage variants depending upon the volume of insulating oil o be filtered. If higher capacity plants are required by the clients we can customize our plants to fulfill their requirements. The plants are also designed as mobile units besides the regular stationary unit. For outdoor usage they are supplied with and enclosure. The plant treats the unqualified turbine oil and removes the impurities from it to improve its quality. It efficiently removes water, gas and other impurities especially from emulsified turbine oil.   Features: Automatic systems with automatic advance system for safety, pressure, electricity and temperature constancy with infrared liquid- Has a trapezoidal, spiral, automatic back flushing system. Automatic Unmanned, On-line oil purification with turbine or water turbine Breaks emulsification thoroughly with high- molecule polymeric material Thoroughly clears the liquid water, free water and 80% dissolved water with effective dewatering with one and two step dehydration method Distinctive technique removes impurities by filtering through double FH trapezoidal network and absorbing by high polymer material Has the capacity to equal or surpass 200 and make the cleanness lower grade 6(NAS1638) with its advanced dielectric condensation devices.   This Vacuum Turbine Oil filter uses an advanced detaching theory of membrane which clears water and emulsification to purify the lubricant. The oil emulsifies to a much lesser degree after treatment. This TYA series prevent damage to the lubrication system and extends the life of both the insulating oil and the machinery.

our oil filtration plants are used to remove impurities from transformer and switchgear oil such as moisture, dirt, air and other gases. This is a `low temperature and high vacuum` principle based equipment as per the international standards 6034 (1989) and its latest revision. We manufacture plants of variable capacities of 600 to 10000 lph which can be customized to special capacities if required by the clients. This plant takes the impure oil into the system through the inlet ball valve and then pumps it through by a positive displacement pump. A filter prior to this removes solid particles up to 1mm size and magnetic particles. After heating the oil up to 60°c it passes through the cartridge filters, where particles up to 5 microns are filtered. A specially designed vacuum chamber removes moisture, air and all the gases with the help of vacuum. The oil falls by way of gravity over the media inside forming a thin film of oil, exposing a larger surface area. The dissolved moisture and gases are evacuated and the oil is ready.  

our filtration plants purify and upgrade transformer oil to comply with standard specifications. These plants can be designed as per customer’s specifications and are also available in varying capacities covering a whole range of applications in low, high and extra high voltage equipments. They perform the following functions:   removal of suspended impurities such as dust, rust, scales, colloidal carbon oxidation sludge etc. Up to < 1 micron.   degassing and dehydration of transformer oil with vacuum circulation of heated oil and filling of treated oil in transformer tank prevention of acid formation by evaporation and adsorption method

During its operation of generating, transmitting and distributing power transformers give out heat which is absorbed by insulating oils. This oil has a tendency to absorb moisture from windings which leads to gradual deterioration of dielectric strength. Our filtration systems provide economical and efficient methods of purifying this lubricant. The unit consists of:   Filter Unit, Indirect system of Oil Heating, Vacuum Dehydration / degasification Unit Condenser and condensate receiver Feed and delivery pump Piping & Valves Control Panel   Components of Plant The filter unit is a coarse strainer with a wire mesh filter element for retaining solid particles and a powerful magnet for retaining magnetic particles. It has round filter paper discs held under spring compression. Specially designed heaters with low watt density heat the auxiliary heating oil, which in turn heats the transformer oil maintaining a temperature of 70-80 C. The cylindrical external pressure vessel is fitted with various shallow drip trays and a specially designed spray pipe to increase surface area. The vapor from dehydration chamber is condensed in a condensate receiver of welded M. S. construction. There are feed and delivery pump of rotary gear type coupled directly with motors. Water Separator Collect the water produced. A centralized control panel has indicators for all electrical devices. Imported thermostat Thermometer for measuring temperature Pressure & Vacuum gauges Flow control indicator Electronic Float Control Electrical instruments, voltometers and ammeters Electrical overloads and overload releases for safety of motors.
