The North American large-frame rotary compressors manufactured by  Tecumseh Products Co., Ann Arbor, Mich., has been expanded to include new products for the industrial, residential and specialty air-conditioning markets.

The high efficiency RN family of rotary compressors covers a capacity range of 18,000 to 32,000 Btu/hr operating with R134a, R407C and R410A refrigerants. Rotary compressors are highly efficient and lightweight, and are less noisy but more reliable compared to reciprocating counterparts, Tecumseh says.

The RN R134a large-frame unit is specifically designed for cooling applications in the process, telecommunications and electronic markets, as well as mobile transport segments.
