Alcoil announced the issuance of US Patent No. 9,459,057 and European Patent EP 2 948 725, which relates to an improved and advanced refrigerant evaporator design.

The patented technology is used as an air-to-refrigerant heat exchanger to cool air or reject heat in industrial or commercial evaporators and heat pump systems. The design includes a built-in refrigerant distributor to provide uniform refrigerant feed to the heat exchanger tubes over a wide range of operating conditions.

The primary benefit results in significantly higher evaporator performance, part load operation to 20 percent load without liquid or oil dropout, and the ability to perform a full range of coil orientations.
