The GP series is a line of portable chiller units that use R410a refrigerant designed to meet the regulatory requirements that will take effect in 2010. R410a refrigerant is chlorine-free, and complies with the Environmental Protection Agency’s guidelines. The benefits to R410a include improved system efficiency as well as higher capacity rates. The chillers range in models from 20 to 210 kW (5 to 60 tons) of refrigeration. Models are available in air- , remote air- and water-cooled versions and offer a leaving coolant temperature range of 20°F to 80°F (-7.5°C to 30°C). An electronic modulating capacity control maintains leaving fluid temperature to within 0.1° F, and electronic sensors with digital readout include leaving and entering fluid temperatures, compressor suction pressure, compressor discharge pressure, condenser inlet temperature, superheat, sub-cool, pump pressure and tank level.
