The new role being played by Azane, a division of Scottish OEM Star Refrigeration, was explained by Caleb Nelson, Azane’s VP of business development, at the IIAR Natural Refrigeration Conference & Expo last month.

In early March Star and Tustin, Calif.-based contractor Controlled Environments Construction (CEC) announced a joint venture to market low-charge ammonia refrigeration systems previously sold by Azane as Azane freezers.

The new company, Controlled Azane Refrigeration (CAZ), also based in Tustin, will serve as a “sales vehicle for freezers into the cold storage market,” explained Nelson. CAZ is being led by president and CEO Rick Loesel, a veteran of the refrigerated and frozen food industry.

Meanwhile, Azane, which remains independent of the joint venture, will focus on serving cold storage and other industries with its low-charge ammonia chillers.

This is the most efficient chiller we’ve ever built."

Nelson said Azane has come out with a new, more efficient version of its low-charge ammonia chiller that the company is planning to deploy in an industrial processing plant in Cedar Rapids, Iowa.

“This is the most efficient chiller we’ve ever built,” said Nelson.

The Azane 2.0 chiller, which features a reciprocating compressor rather than the screw compressor used in Azane 1.0, focuses on part load efficiency, he explained. This allows for higher efficiency during off-peak times and when ambient temperatures are lower.

The newest chiller also features a stainless steel control panel and plate-and-shell technology, which eliminates the surge drum. It also has a smaller footprint.

“It is a simplified system, and it drives some of the costs out,” said Nelson. “It’s helping the business case a lot for ammonia. It can show much better lifecycle cost savings.”
