30GT FlotronicTM Air-Cooled Reciprocating Liquid Chiller Features

Carrier's 30GT air-cooled reciprocating chillers offer peak operating performance in nominal sizes ranging from 15 tons to 400 tons (53 to 1400 kW). Sizes up to 35 tons offer thermostatic expansion valves (TXV) while sizes 36 tons (127 kW) and larger offer either standard TXV controls or Carrier's patented Flotronic long-stroke expansion valve (EXV) controls. With over 25,000 long-stroke EXV Flotronic chillers installed worldwide, Carrier's 30GT chillers are favored by specifiers and customers. The powerful 30GT Flotronic chillers incorporate integrated microprocessor control and refrigeration cycle optimization devices. The electronic expansion valve (EXV) and the microprocessor controller allow the chiller to operate at low pressure differentials, and accurately control refrigerant superheat during start-up and load changes. The result is efficient energy usage and accurate leaving-fluid temperatures. (LWT) These chillers offer cost saving advantages because they are smaller and easier to install as well as exceptionally efficient. Full and part load EERs (Energy Efficiency Ratios) are up to 9.9 for full load and 12.0 for part load resulting in a significant savings in operating expense.
