Our TECOCHILL “STx Series” and “DTx Series” product lines offer water-cooled engine-driven chillers, ranging from 150 to 400 tons of cooling capacity. Each natural gas engine drives a variable-speed single-screw rotary compressor, connected to a standard vapor compression refrigeration system utilizing environmentally-friendly HFC-134a refrigerant.
TECOCHILL’s “STx Series” models feature a single driveline (one engine) to provide up to 200 tons of capacity, whereas TECOCHILL’s “DTx Series” models use dual drivelines (two engines) to provide up to 400 tons of cooling capacity.
