Emerson launched fractional-horsepower, low-temperature Copeland Scroll™ compressors (ZF*KA) that utilize liquid-injection technology to cool discharge temperatures and reduce compressor stress while meeting upcoming federal regulatory requirements. The U.S. 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 U.S. Department of Energy (DOE) has proposed the enforcement of its new WICF efficiency mandate in 2020, as measured by the annual walk-in efficiency 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 that rely 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 delivering high efficiencies and reliable performance.
