Offered in a range of configurations such as one-, two- or three-channel chillers, system can be supplied with air- or water-cooled condensers. With a temperature range of -94 to 392oF (-70 to 200oC) and stability of +/-0.1oC, the chillers have cooling capacity ranges from 1,700 to 256,000 BTU/hr (500 to 75,000 W) and up to three independent loops. Cooling fluid types include water, deionized water, synthetic fluids, ethanol, ethylene glycol or propylene glycol/water mixtures, and mineral oil, or others as required. Embedded computer control monitors critical system functions and controls refrigerant valves. Built-in self-diagnostics test for critical functions such as refrigerant temperatures, voltages and sensors.
