Desuperheater for Refrigeration | Maniks
Desuperheater is a device used to save the energy by cooling a superheated steam in a power generation plant. Superheated steam has important advantages on certain applications, for example, when used in power stations to drive turbines. For efficient use on heating applications however, the steam must be desuperheated. 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 superheaters 
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 desuperheaters, water is used.
Maniks are having comprehensive range of dessuperheater 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. 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.
