CHAMBERSBURG, Pa. — Azane Inc., the United States subsidiary of United Kingdom-based Star Refrigeration, has introduced a new low-charge ammonia packaged freezer for the U.S. market.

The Azanefreezer is a complete refrigeration package housed in one unit with two separate ceiling mounted coolers arranged for reverse cycle defrost. The unit contains two screw compressors, designed for industrial installations and located for easy maintenance access. Its low pressure receiver offers efficient operation and allows for a low charge of ammonia. Azane said the enhanced aluminum evaporator design provides better performance from the lowest amount of ammonia, without the need for any pumps as found in traditional ammonia systems. Reverse cycle defrost provides for more efficient defrost.

The company said the use of the natural refrigerant ammonia, a zero global warming potential (GWP) and non-ozone depleting substance, should safeguard the Azanefreezer from future environmental legislation. The system has a life cycle of 25+ years at maximum operational performance.

Expanding on the benefits of ammonia, Derek Hamilton, Azane’s U.S. business development manager, said, “All Azanefreezer components have been selected to minimize the risk of refrigerant leakage, reduce refrigerant charge, simplify maintenance, and prolong plant life expectancy. The Azanefreezer has been installed in public warehouses across Europe for over 20 years due to the phaseout of R-22. It is a fully tested and proven technology which has now been made available to U.S. customers to aid the transition from ozone depleting refrigerants by 2020.”
