Tecumseh Products, the United States, has unveiled a new range of small compressors, the TC series, designed for hydrocarbons R290 (propane) and R600a (isobutane). With a capacity range of 300-1,500 BTU/h, the smaller TC compressors “have all of the U.S. Department of Energy efficiency regulations covered,” said Tony Carstensen, at Tecumseh. The compressors, which will be in production by the end of 2016, would typically be used in self-contained/stand-alone beverage coolers, reach-in refrigerators and freezers, and vending machines.

Tecumseh also announced that for self-contained/stand-alone commercial refrigeration equipment with capacities of less than 0.5 HP, Tecumseh continues to support propane as the refrigerant of choice, within the charge limitations (150g) and safety requirements mandated for A3 refrigerants. “R290 offers 25% energy savings. It’s the best option where you can use 150 grams and 0.5 horsepower or less,” said Carstensen.

Tecumseh sees the OEM marketplace for its compressors divided into two camps, one that embraces hydrocarbons and one that avoids them. The first group “likes the efficiency R290 gives them and are concerned about SNAP and DOE regulations,” said Carstensen. In May 2015 Tecumseh was acquired by Mueller Industries and Atlas Holdings, which each own a 50% share of the company.
