What is Desuperheater? Conceptual Information about
Water heater & its Applications .
The primary function of the desuperheater is to lower the temperature of
superheated refrigerant or other vapors in process. This temperature reduction of
gas is accomplished as a result of the refrigerant being brought into direct contact
with other liquid called water. The sprayed water is then evaporated.

If the gas is too hot, it will cause equipment (condenser) to damage and hence the
condenser efficiency is decreased.
The overall purpose of a desuperheater water heater is to provide effective heat
transfer between refrigerant and water. And a highly effective desuperheater water
heater design and application results in costly problems to be avoided, including
extended shutdown and startup times.
Desuperheater’s water heater comes in a variety of configurations including probe
style with variable or fixed nozzle, double venture and venturi. With a design that
has finely controlled water spray that results in reducing refrigerant temperature at
saturation level.
A desuperheater is a device that cools superheated gas to a temperature close to its
normal temperature, typically by spraying fined droplets of water into the flow of
