The SD(H) compressor unit desuperheater contains a water high temperature control. It is factory set
to 140°F. The desuperheater also contains a refrigerant low temperature limit switch, which is factory
set to 125°F. Also, a freeze protection control is designed to operate the circulating pump when water
temperature drops to 40°F, in order to provide water circulation independent of compressor operation.
The GSTE storage water heaters are available in 60, 80 and 119 US gallon capacities, all of which
have a 4.5 kW electric heating element, which provides the following recovery rates for increases in
water temperature.
