Maniks is a leading Indian supplier of steam desuperheaters, specializing in energy-saving equipment for process and cogeneration plants for over thirty years. A desuperheater cools superheated steam or gas by adding water, making it useful for various applications, but superheated steam can hinder performance and damage sensitive equipment. Maniks' desuperheaters are designed for refrigeration systems, utilizing ammonia water to cool refrigerant gas during its cyclical process.

Definition of Desuperheater
Desuperheater is an energy conservation product used to lower down
the temperature of a superheated steam in a system where high
amount of superheated heat is generated and emitted in the
atmosphere

Superheated Steam/Gas
Superheated steam is a very high temperature water vapor generated
by further heating the saturated steam. Same procedure is carried out
for saturated gases.

Desuperheating Process
 Most common way of lowering the temperature of superheated steam
or gas is direct addition of water or relational gas. With the help of
Desuperheating process the temperature of this superheated steam can
be used for some other applications such as
1. sanitary hot water
2. room heating
3. hot water for processes
4. cleaning water

Disadvantages of Desuperheated Steam
 Superheated steam has many disadvantages some of them are listed
below Many devices have lowered their performance when supplied
with the superheated steam for example distillation columns
 To deal with superheated steam we require very high rated and
expensive equipments.
 The temperature of superheated steam can damage sensitive
equipments of the system.

 Desuperheater theory
 Desuperheater is a device used to cool the steam in a power plant. When steam is
used for mechanical power plant such as driving the turbine rotor by expanding
across turbine blades, it will be more efficient when the steam is superheated. A
Desuperheater is a device which lowers the temperature of the superheated steam
so that it can be effectively used for heating or other industrial applications. This
action is performed by injecting a predetermined amount of water in to the stream
of steam flow.
 Steam Desuperheater is used to spray water into steam so that water gets mixed
with steam resulting in reduction in the temperature of the outlet steam.
 1. Integral type- Desuperheater is in-built with actuator so that there is no need to
separate spray water valve
 2. Non Integral type- Desuperheater nozzle and water valve are separate units

 Working of Maniks Desuperheater
 Maniks Desuperheater is designed to work in a refrigeration system so
it uses ammonia water inside to cool the refrigerant gas. When
refrigerant gas in a refrigeration system is compressed in a compressor
it passes though a condenser where it gives off heat and changes to a
liquid state and then it passes through an expansion valve to an
evaporator coil to absorb heat and change the refrigerant back to
gaseous state for recompressing in the compressor to complete and the
refrigeration cycle. This cycle is performed repeatedly in refrigeration
systems.
