Leading Scroll Chiller Manufacturers

Control is established by staging the compressors. They come with several components, such as: starter/control panels, drain valves, flow switches, electronic expansion valves, brazed plate evaporators, air-cooled or water-cooled condensers, subcoolers, interconnecting piping and (optionally) partial heat recovery.

Compact, they usually accommodate smaller systems, used commercially for systems with less than 30 TR capacity, and can be designed for outdoor use or industrial indoor use. Industrial-grade scroll chillers are ideal for use in air conditioning large office buildings and other commercial and industrial facilities.

They are also good for such applications as low temperature processing, heat recovery, thermal storage and ice-making. Engineers recently modified scroll chillers to enable them to run at part load capacity with a single compressor. Before, they were only able to run at full capacity without human manipulation outside of the powered machine.

An advantage of scroll chillers is their energy efficiency. They are also becoming more environmentally friendly, as many companies seek to reduce use of refrigerants with high Ozone Depletion Potential (ODP). Scroll chillers are also easy to install and easy to maintain, and they can be customized to a variety of energy, mechanical and sound configurations.

With this customizable sound capability, they work well in sound sensitive environments. Because they have fewer moving parts than, for example, reciprocating chillers, scroll chillers theoretically boast greater reliability.
