Filtrine ES-4-RF-IW Drinking Water In-wall Chiller

Persons Served: 200, 1/4 HP Compressor, 4 gal Storage Capacity


Filtrine's non-recirculating Model ES-4-RF-IW Chiller/Purifier serves a consistent chilled 50°F drinking water. Unlike conventional electric water coolers (EWC's), Filtrine's ES Chiller/Purifiers contain a storage-type cooling tank with a stainless steel immersion coil evaporator. This unit builds up a reserve of chilled water during low usage periods to fill drinking water bottles and handle peak demands yet still meet the low average draw. A single free-standing unit uses less energy than multiple EWC’s serving a comparable population. The Particulate Pre-Filter and Taste Master® purifier ensure water quality control.
