Azane Inc Launches Natural Ammonia Packaged Azanefreezer in the US

Share Article

The Azanefreezer range of air cooled ammonia packaged units has been designed as a natural replacement for R22 systems.

The Azanefreezer has zero GWP and is exempt from EPA R22 phase out legislation

All Azanefreezer components have been selected to minimize the risk of refrigerant leakage, reduce refrigerant charge, simplify maintenance and prolong plant life expectancy.

One of Europe’s leading independent contractors of industrial cooling and heating solutions, Star Refrigeration, has launched a new subsidiary Azane Inc to manufacture its climate friendly and high performance low charge ammonia freezers for the US market.

Azane Inc has been launched to provide a natural solution for the US cooling industry, who are currently affected by the prospect of the upcoming R22 phase out and potential HFC phase down. The company specializes in low charge packaged ammonia refrigeration systems, including the energy efficient air cooled Azanefreezer (a companion to the Azanechiller) that is designed for use in freezer warehouse.

The Azanefreezer, essentially an ammonia condensing unit, 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. The enhanced aluminium evaporator design provides better performance from the lowest amount of ammonia, without the need for any pumps as found in traditional ammonia systems.

The utilization of low charge, natural refrigerant ammonia, a zero GWP and non ozone depleting substance, should safeguard Azanefreezer from future environmental legislation. The system has a life cycle of 25+ years at maximum operational performance. It also uses reverse cycle defrost – currently the only system to offer this – which defrosts more efficiently.

Expanding on the benefits of ammonia, Derek Hamilton, Azane’s US Business Development Manager, says: “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 phase out of R22. It is a fully tested and proven technology which has now been made available to US customers to aid the transition from ozone depleting refrigerants by 2020.”

The ammonia packaged unit has been specifically designed to operate with as little as one tenth of the charge of a traditional refrigeration system, therefore avoiding the burden of OSHA’s PSM and the EPA RPM requirements.
