What is Desuperheater water heater? desuperheater | Page 2

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
Manor 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 Manors 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
