Dependable chiller performance

Designed with a comprehensive group of built-in protective features, the EP1 assures dependable performance with minimum downtime. A 2.5 minute anti-cycle timer prevents excessive compressor cycling. A low-load thermostat extends operating time at idle and low-load conditions and a non-cycling low pressure switch specifically designed for portable chillers helps protect the compressor from damage and unnecessary wear.

More standard features

The EP1 Series Portable Chillers come equipped with standard features that other manufacturers would offer as options. Features which guarantee long life, simple operation, and quality end results are included as standard with this series.
