Drying filter of diode laser chiller

Drying filter of diode laser chiller

 

In the glass laser chiller refrigeration cycle, it is necessary to prevent the entry of moisture and dirt (oil, iron, copper shavings, etc.). The source of moisture is mainly the trace amount of water contained in the newly added refrigerant and lubricating oil, or the moisture that comes from entering the air when the system is overhauled. If the moisture in the system is not eliminated, when the refrigerant passes through the throttle valve (thermoexpansion valve or capillary), the pressure and temperature will sometimes cause the moisture to freeze into ice, blocking the channel and affecting the normal operation of the refrigeration device. Therefore, a dry filter must be installed in a small water chiller refrigeration system.
