 Design of Maniks Desuperheater:

 Basic of Desuperheater:  Desuperheater is basically an energy conserving device used by the industries where the large amount of heat energy is generated. Maniks are having comprehensive range of desuperheater supply since last three decades. Maniks introduced variety of desuperheaters with precise temperature control for various applications in chemical or oil & gas process plants where the available refrigerant is at superheated conditions. These Desuperheaters have high performance, custom design, easy to install and requires very low maintenance. Desuperheater

 Types of Desuperheater:  Desuperheating is the process by which superheated steam is restored to its saturated state, or the superheat temperature is reduced. Basically there are two types of super heaters  Indirect contact type - The medium used to cool the superheated steam does not come into direct contact with it. A cooler liquid or gas may be employed as the cooling medium, for example, the surrounding air. Examples of this type of desuperheater are shell and tube heat exchangers.  Direct contact type - The medium used to cool the superheated steam comes into direct contact with it. In most cases, the cooling medium is the same fluid as the vapour to be desuperheated, but in the liquid state. For example, in the case of steam desuperheater, water is used.

 Working of a Desuperheater:  Water or a liquid used inside the desuperheater comes in to contact with the superheated steam or heat energy and by absorbing the energy from steam superheated liquid will evaporates and reduces steam temperature. This simple technique is used to minimize the temperature of the steam. The outlet steam temperature is maintained by the quantity of the water or superheated liquid that is evaporated.  To reduce the time of suspension of the water particles in the steam it is proposed to inject hot water near the saturation temperature of the steam to be cooled so that the latent heat is extracted to evaporate the injection water. 

 Maniks Desuperheater:  Maniks are having comprehensive range of desuperheater supply since last three decades. Maniks introduced variety of desuperheaters with precise temperature control for various applications in chemical or oil & gas process plants where the available refrigerant is at superheated conditions. This Desuperheater has high performance, custom design, easy to install and requires very low maintenance.  In the normal refrigeration cycle, a refrigerant gas such as ammonia, Freon is compressed in a compressor, passes through a condenser where it gives off heat and changes to a liquid state and then is passed through an expansion valve to an evaporator coil to absorb heat and change the refrigerant back to a gaseous state for' recompressing in the compressor to complete the refrigeration cycle.
