30HS Model E Condenserless Water-Cooled
Reciprocating Liquid Chiller Features
The Carrier 30HS is a condenserless, packaged water-cooled, reciprocation water chiller available in nominal sizes from 70 to 160 tons (250 to 560 kW) and feature a microprocessor-controlled electronic expansion valve (EXV). The 30HS unit is shipped with a holding charge of refrigerant and specially designed for applications with remote fluid or air-cooled, or evaporative type, condensers. The system monitors safety functions and controls unit capacity to maintain leaving chilled fluid temperature. The micro-processor controls loading and unloading of compressors to match changing cooling load requirements and features extensive self-diagnostics as standard. Designed to reduce installation time and costs, the 30HR fits easily through standard doorways, and requires minimal floor space on the job. At full load, 30HR chillers provide EERs (Energy Efficiency Ratios) up to 14.3. Since the chiller normally works at part load for 97% of its operating time, a substantial reduction in operating cost can be realized.
