Superheated steam is a steam that is at a temperature higher than the normal temperature for the steam pressure. For instance, steam at a pressure of 3 bar g has a saturation temperature of 143.762°C. If further heat is added to this steam and the pressure remained at 3 bar g, it would become superheated. So, desuperheating is the method by which superheated steam is restored to its saturated state, or the superheat temperature is reduced.
Maniks is the most reputed Indian brand with a history of 30 years for manufacturing reverse jet pulse valves used in bag-filter applications and the sequential timers used in conjunction with them. These are used in dust collector equipment for cement, steel and such other industries. The company was started by Mr. Shekhar Kulkarni, an IIT Mumbai alumnus, with a vision to substitute imported products with Indian make products. The primary aim was to produce reliable products with excellent quality and service.
With the huge experience of Maniks Guru in the Refrigeration and Air-conditioning Industry, Maniks has selected "Waste Heat Recovery through AC & R Compressors" as the measure to achieve large energy savings in the industries like Dairy & Food Beverages, Hotel & Hospitality, Pharmacy & Chemical, Textile and Specialty Hospitals etc. The "Desuperheater Water heater" produced by Maniks has emerged as the most benefitted device for an AC & R plant that Enhances compressor's reliability, performance and long life and also delivers Free of Cost Hot Water and besides other concealed benefits.
What is Maniks Desuperheater?
Maniks “Desuperheater Water Heater "is a unique heat exchanger that produce hot water/ fluid to the highest temperature of 80℃. The fluid /water can be boiled or heated by recovering the superheat of the refrigerant gas which is otherwise wasted to the environment through air/ water cooled condensers. The generated heat is regained with almost zero operating cost.

Working of Desuperheater:
In a usual AC & R system, the refrigerant temperature rises in tune of 80℃ to 120℃ after compression. The refrigerant is further put to the air/ water cooled condenser to condense near about 40℃.
While the condensing of refrigerant in the condenser, the total heat contained in this high Temperature/high pressure gas gets wasted to the atmosphere.
This superheat of the gas which is part of the total heat content of the gas, has a substantial heat potential provided the same is reclaimed efficiently and is optimized for energy saving
Maniks Desuperheater Water Heater is the ultimate accessory for an AC & R plant that can be used to remove superheat of the refrigerant.

Desuperheater Design:
Double Walled “Tube in Tube ", vented, counter flow heat exchanger. Vent tube have serrations on outer & inner surfaces to avoid cross contamination of water/ fluid and refrigerant. Each and every tube has a tube inside it that allows water/ fluid to travel in an opposite direction.
The Desuperheater Water Heater is actually installed before the oil separator and the condenser. The refrigerant gas travels through the series of different tubes in the Desuperheater device before it enters the condenser. Normally the Desuperheater Water heater is manufactured considering the hot/warm water requirement for the processes. When needs of refrigeration & hot water are not simultaneous, a " Recirculation " type system is provided where hot water is generated, stored & maintained in an insulated tank. The hot water generated then can be utilized as and when required by the customers.
The Desuperheater water heater can be easily modified on reciprocating, screw or scroll type chillers.

Benefits of Maniks Desuperheater Water Heater:
A) Desuperheater Water Heater removes the superheat from the refrigerant Gas and reduces required Cooling Water flow in the condenser. This subsequently reduces:
• Water loss through Cooling Tower circulation.
• Power consumption in Cooling Water Pump & Cooling Tower fan.
• Wear & tear of Cooling Water Pump & Cooling Tower fan.
B) Reduction in condenser pumps power consumption.
C) Hot Water that is generated from the Desuperheater water heater will be used as “Preheated Boiler Water." This will minimize Boiler Operating Hours. This subsequently reduces:
• Power consumption and Wear & tear in Combustion Air Fan, Fuel Pump, & Water pump
• Consumption of Fuel through Burners etc.
• Frequent Scaling of tubes
