Emerson ZF*KA Compressors


Emerson has launched fractional horsepower low-temperature Copeland Scroll compressors that utilize liquid-injection technology to cool discharge temperatures and reduce compressor stress while also meeting upcoming federal regulatory requirements.

The Environmental Protection Agency (EPA) will be phasing out the use of R-404A in new remote condensing units for walk-in coolers and freezers (WICF) in 2018. Additionally, the Department of Energy (DOE) has proposed the enforcement of its new WICF efficiency mandate in 2020, as measured by the annual walk-in efficiency (AWEF) standard. The new Copeland Scroll ZF*KA compressor line simultaneously addresses the need for compatibility with new refrigerants, tougher energy standards and highly reliable, smaller-capacity systems.

The ZF*KA compressors are designed for walk-in freezers relying on outdoor condensing units that will require compressors that can mitigate the higher discharge temperatures produced when using new refrigerant alternatives in low-temperature applications. The liquid injection technology allows the compressor to cool the discharge temperature while also delivering high efficiencies and reliable performance.
