  • The coaxial heat exchanger is designed as a "tube in tube" structure. The outer tube is made of steel/copper, and the inner tube can be titanium, copper, copper-nickel depending on the requirements of working condition.  For the inner tube is has many spiral grooves on the surface, which will enlarge the connection surface and get more heat transferred. Since the temperatures of refrigeration and water are different, the heat will transfer from one with the high temperature to the other one. This is the counter-flow heat transfer principle, which allows the extensive exploitation of the super-heating of the refrigerant vapor and a super-cooling of the liquid refrigerant.

  • The GEG series liquid line filter drier/sight glass combination is a liquid line filter drier with a sight glass brazed directly to the outlet side of the filter drier. The filter drier is designed with a 3A molecular sieve desiccant for excellent moisture adsorption with CFC, HCFC and HFC refrigerants. The filter media removes small particles down to 10 microns in size from the refrigerant to help prevent plugging orifices and tubes. The pre-assembled combination reduces the amount of field brazing required, saving both time and reducing the potential for leaks. The sight glass allows technicians to see the refrigerant in its’ current state. It helps to identify poorly charged systems that have poor airflow across the condenser coil or system. The sight glass has a built-in moisture indicator which provides visual color change from green to yellow in response to the moisture content of the refrigerant, indicating the need for service.
