Simple to install and highly reliable

The Series R® helical rotary chillers offer easy installation, application flexibility, high reliability and optimized energy efficiency due to its direct-drive compressor design that uses fewer moving parts than gear compressors.

Precise temperature control

The Series R chillers are uniquely suited for both industrial and commercial applications that require precise temperature control while also eliminating the need for expensive buffer tanks.

Its infinite unloading compressor, wide operating temperature range, electronic expansion valve and short anti-recycle timers give it flexibility for almost any high-performance cooling and heating system.

Refrigerant options

These chillers are designed to operate with either R-134a refrigerant or R-513A — a nonflammable, nextgeneration refrigerant that delivers the same capacity with a 55% lower GWP.

Compact size reduces installation challenges

Chiller replacement is faster, cheaper and less disruptive due to the chiller’s compact size, which fits into most existing mechanical rooms without requiring additional floor space or wall tear-outs. Most units can pass through a standard door opening, and both single- and dual-point power connections can take advantage of existing wiring.
