Steam Desuperheaters Dealers

steam desuperheaters Desuperheater is a device which is sprays the high pressure water in the steam line thereby reducing the steam temperature to a point at or nearly at saturation temperature. An attemperator controls steam temperature while a desuperheater removes whatever superheat there is in steam.

Desuperheatersare used to lower the temperature of superheated steam to the desired set point by injecting atomized water into the superheated steam flow. IndiTech has a wide range of desuperheaters that provide precise steam temperature control for variousapplications. High performance custom designed nozzles ensure that water is atomized into a fine mist at all process conditions. The complete range of IndiTech desuperheaters is easy to install and requires low maintenance.   Variable Nozzle / Multi Nozzle Desuperheaters (Series 230) IndiTech Series 230 variable nozzle desuperheaters are best suited for applications involving high load fluctuations. They are designed to controlthe quantity of spray waterat the point of water injection, thereby eliminating the need of a separate water control valve. This is achieved by coupling the desuperheater with an actuator and subsequently varying the number of injection nozzles in operation.Nozzle opening is controlled through precise positioning of the desuperheater stem in response to feedback from a controller and downstream temperature sensor. Temperature reduction occurs as the fine mist ofwater rapidly vaporizes into the superheated steam.   Features No external cooling water control valve required. Capable of maintaining steam temperature to saturation + 6°C. High performance spray nozzles that atomize water into a fine mist. Nozzles are stellited for water pressure drop more than 25 bar. Single piece forged body. Wide range of Kv / Cv values by using special nozzle combinations. All sealing joints (body-seat & body-nozzle holder) are stellited to provide leak tightness even after prolonged usage. Spray nozzles vacuum brazed to the body to prevent leakage, thereby avoiding disturbancesin the water swirl pattern and atomization. Approved under IBR (Indian Boiler Regulation Act).

• Sizes: 1.1/2" X 3" or 2" X 4"

Steam Desuperheater is used to spray water into steam so that water get mixed with steam resulting in reduction in the temperature of the outlet steam. Desuperheater can be classified into two. Non-Integral type Desuperheater -Desuperheater nozzle and water valve are separate units, Integral type Desuperheater -Desuperheater is in-built with actuator so that there is no need to separate spray water valve.

Variable Annulus Desuperheater (VAD) Variable Orifice Desuperheater (VO-II and VO-76) Mechanical Atomizing Desuperheaters (MA-I / MA-IU, MA-II / MA-IIU, MA-IIIU) Spring Assisted Multiple Nozzle Spray Desuperheater (SAMN-U) Steam Atomizing Desuperheater (SA-35) Multiple Nozzle Spray Desuperheater (MNSD)

• RANGEABILITY: Maximum 45 to 1.

The evolutionary series 800 Desuperheater i.e. Varitrol variable spray nozzles unit can be used in many applications to efficiently reduce the superheated steam or other vapours to temperature approaching saturation. The superheated vapour is passed through a section of pipe into which is fitted a spray nozzle that produces dispersed droplets from a supply of pressurized condensate. These finely atomized particles promote almost immediate evaporation. The required heat being absorbed from the superheated vapour, thus reducing the temperature.

Steam PRDS is used for Steam Conditioning Services for the reduction of pressure and temperature of steam. It is a combination of Control Valve for the pressure reduction purpose and atomizing nozzles through which water is sprayed into steam for reducing the temperature. PRDS can be of two types 1. Combined PRDS Both PRV and Desuperheater in a compact single unit 2. Split PRDS Separate PRV and Desuperheater

Variable Nozzle Desuperheater are provided for accurate temperature control & Selection best on process parameters requirement. These are designed, engineered and manufactured in house which ensures high quality. Fixed Nozzle Desuperheater: The Simplest Design in De super heater family Mainly used when the pressure difference between the main steam line and spray water is high Inline type assembly for steam line size 6" NB and above Mini cooler for steam line size up to 4" Maximum Turn down 4:1 Variable Nozzle Desuperheater: Best Design in Desuperheater family Constant pressure drop across the nozzle High turn down up to 20:1 Better downstream temperature control

The most practical way of reducing the superheat value of steam is by the direct addition of water. To achieve temperature stability of the conditioned steam and prevent thermal shock in downstream pipes, cooling water must be atomized. It is also necessary to have a correct mix of superheated steam and cooling water.

Steam DeSuperheater is used to spray water into steam, so that it gets mixed, resulting in reduction in the temperature at the outlet.DeSuperheater can be classified into two:A. Non-Integral type DeSuperheater: DeSuperheater nozzle and water valve are separate units.B. Integral type DeSuperheater: DeSuperheater is in-built with actuator, so that there is no need of separate spray water valve.

We are actively involved in the fabrication of superior quality Steam Desuperheater. Over the years we have mastered the technique of designing unmatched designs of Steam Atomizing Desuperheater. The use of finest grade raw materials ensures the durability and reliability of our Steam Desuperheater. We are well reckoned as one of the prominent Desuperheater Manufacturers in Pune, Maharashtra. Features Highly reliableEasy to useEffortless maintenanceExtremely durable

• Application: The potential to reduce the degree of outlet superheat is limited by the capability of control system. Almost all desuperheaters are used to reduce the steam (or gas) temperature as close to saturation as possible. Etc
