Important specifications to consider when searching for industrial chillers include the total life cycle cost, and chiller cooling capacity in tons, BTU’s/hour, or kW. Process pump specifications that are important to consider include the process flow, process pressure, pump material, elastomer and mechanical shaft seal material. If the cold fluid temperature is lower than -5°C, then a special pump needs to be used to be able to pump the high concentrations of ethylene glycol. Other important specifications include the internal liquid tank size and materials and full load amperage. The OPTI TEMP® systems feature our “Advanced Refrigeration Capacity Control” (ARCC) circuitry. This patented industry leading circuitry allows the industrial chiller to operate from “zero load to full load” (without cycling the compressor) while providing excellent temperature stability. Another benefit is the ability to operate over a very wide temperature range (from 30°F with antifreeze to 190°F with special materials of construction).
Control panel features that should be considered when selecting an industrial chiller include the local control panel, remote control panel, fault indicators, flow indication, temperature and pressure indication. Additional features include emergency alarms, hot gas bypass, city water switchover, and casters.
