Cold Weather Operation

The CXV Evaporative Condenser is well suited for cold weather applications when used with proper capacity control and freeze protection．When the CXV is operating under load with a minimum condensing temperature of 10℃．The? recirculating water will not freeze．

Under freezing conditions with file fans and the spray pump off，the basin water must be protected from freezing．Electric heaters can be installed in the condenser basin．Optional heaters are available for -17.8℃ and -28.9℃ ambient temperatures based on a 16.09 km/h wind．In addition，the pump suction 1the，pump，pump? discharge fine(up to the overflow)．And the water make-up line should be wrapped with a heat-tracing element and insulated．

　?An alternative method of freeze protection involves the use of an auxiliary sump tank and spray water recirculating pump，located in a heated indoor space． Water drains from the condenser basin to the remote sump，and when the pump is shut off，the water remains in the indoor remote sump．The tank(supplied by others)must be sized to accommodate water in suspension in the condenser(s) plus the water in supply and return piping．Remote pumps (supplied by others)must be selected for the required flow at a total head which includes the vertical lift，pipe friction，plus 7.0 kPa? at the CXV water inlet A valve should be installed in the condenser water supply line to permit adjustment and maintain pressure below 70 kPa at the CXV water inlet．
