What is Desuperheater?
Desuperheater is an exclusive heat exchanger device that produces high temperature hot liquid/ water to the maximum temperature up to 80℃. The water/liquid can be heated by recovering the excess heat (superheat) of the refrigerant (ammonia/freon) gas which is generally wasted to the air through air/ water cooled condensers. The excess heat is recovered for boiling water with almost zero operating cost.
Maniks positions among the world's largest leading providers of Ammonia/Freon Desuperheaters. They also have some expertise in manufacturing and designing such equipments for process, power and eco-generation plants. Maniks has manufactured more than 5000 Desuperheaters since 1990.
Desuperheater Operation:


Compressor Type Discharge Temperature
Screw (Indirect cooled) 70 to 80℃
Screw (Injection cooled) 50 to 60℃
Reciprocating 85 to 110℃
Boosters (Rotary & Reciprocating) 75 to 85℃
In a typical Air Conditioning and Refrigeration products, the refrigerant temperature accelerates in order of 80℃-120℃ after compression. The refrigerant is additionally put to the air/ water cooled condenser to gather near about 40℃.
While the condensing of the refrigerant gas in the condenser, the total amount heat contained in this high Temperature or high pressure ammonia/Freon gas gets wasted to the outside atmosphere.
This superheat of the gas is part of the total heat content of the working gas, has a generous heat potential provided that the same is recovered efficiently and is optimized appropriately for energy saving
Maniks Desuperheater Water Heater is a definitive accessory for an AC and R plants that can be used in order to remove and utilize superheat of the operating refrigerant.
Desuperheater Design:
Double Walled "Tube in Tube ", vented, counter stream heat exchanger. Vent tube having serrations on internal & external surfaces to avoid cross contamination of refrigerants and water/ fluid. Each tube has a tube inside that permits water/ fluid to go in an opposite direction.

Desuperheater Installation:


The Desuperheater Water Heater is introduced before the condenser and the oil separator. The refrigerant goes through the arrangement of tubes in the Desuperheater Water Heater before entering the condenser. Typically the Desuperheater Water heater is architecture considering the hot water needs for the different processes. At the point when necessities of high temperature water and refrigeration are not synchronous, a “Recirculation” sort of framework is given wherein boiling water is produced, stored & kept up in an closed tank. This hot water at that point can be used as and when required.
The Desuperheater water heater can be effectively retrofitted on responding, scroll or screw sort of chillers.
Advantages of Desuperheater Water Heater:

A) Desuperheater Water Heater lessens required Cooling Water stream in the condenser and expels the superheat from the refrigerant Gas. This subsequently reduces:
• Water loss through Cooling Tower dissemination.
• Power utilization in Cooling Water Pump & Cooling Tower fan.
• Wear and tear of Cooling Water Pump & Cooling Tower fan.

B) Reduction in condenser pumps power consumption.
• Desuperheater lowers the power consumption of condenser pump

C) Hot Water created from the Desuperheater will be utilized as " Preheated Boiler Feed Water." This will limit Boiler Operating Hours. This subsequently reduces:

• Power utilization and Wear and tear in Fuel Pump, Combustion Air Fan & Water pump
• Consumption of Fuel through Burners and so on.
• Frequent Scaling of tubes
The COP of the Refrigeration Plant will improve. This subsequently extends:
• Lesser running hours of the refrigeration plant for the given load
• Increased life, lesser Wear & tear of compressor / motor
• Additional sparing in Electricity
