Filtrine's recirculating Model ES-8-RFC-FS 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 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 provide water quality control.
