Emerson Climate Technologies offers the broadest range of high efficiency compressors in the industry. Our Copeland™ compressors range in size from small fractional horsepower to greater than 50 HP and include scroll, hermetic, and semi-hermetic technologies.

Leveraging the engineering expertise gained through over 85 years of experience, Emerson Climate Technologies is proud to offer a line of high efficiency Copeland compressors that are up to 30% more efficient.

Scroll

High efficiency for medium temperature

Emerson Climate Technologies offers a new solution for

restaurant and convenience store operators. The latest

generation of Copeland Scroll™ ZS*KA compressors is

optimized for medium temperature applications and offer

on average a 15% improvement in annual efficiency. A wide

operating range makes the ZS*KA a flexible solution for many

refrigeration needs:

•Covers evaporating temperatures from -25°F to 45°F.

•Qualified for multiple refrigerants including: R-404A, R507,

R-134a, R-407A/C, and R-22.

•Recommended for walk-In refrigerators and freezers, soft

serve machines, frozen beverage machines.

High efficiency for low temperature

The Copeland Scroll ZF*KVE compressor has been

specifically designed with vapor injection for low temperature

applications. The optimized design of ZF*KVE together with

subcooling from vapor injection provides a 50% increase in

capacity and 20% increase in efficiency on average at the low

temperature rating condition.

Hermetic

More than 300 models of Copeland hermetic reciprocating

compressors provide cost effective solutions to systems

requiring a wide range of evaporating capability.

Recent design enhancements include:

• New valve plates improve energy efficiency

• Unique suction mufflers lower sound

• Optimized motors improve starting

• Adhesive-coated gaskets improve liquid handling capabilities

• Redesigned bearing surfaces improve oil flow and

reduce wear

Semi-Hermetic

The Copeland Discus compressor saves energy and

money because it is the most energy-efficient semi-

hermetic compressor available for your refrigeration

needs. In fact, Copeland Discus compressors have led

the industry in energy efficiency for decades, delivering

up to 12.2% more energy efficiency than any reed

compressor technology. And our patented Discus valve

technology is designed to meet a broad range of

application requirements.
