4.5 degrees Celsius below zero temperatures in winter areas, evaporative condensers of the fill pipe must be wrapped insulation material, to avoid pipe blockage or cracking, water dish may be frozen in place should be retrofitted with electric heater.

4.5 * winter temperatures below zero degrees Celsius, evaporative condenser pipes have to be bandaged supplement insulation materials, so as to avoid cracking, water pipe plug or frozen in ice up the local should be retro-fitted with electric heater.

4.5 The winter temperature is lower than a zero degree Celsius area, the evaporative condenser makes up the water pipe to have to wrap up the heat-insulating material, in order to avoid the pipeline jamming or cracks as a result of freezing, Shui Pan is possibly icing up the place should install the

Winter temperatures below zero degrees Celsius in 4.5, back tax and penalties of evaporative condenser pipes must wrap insulation materials, so as not to crack pipe blocked or frozen, water should be fitted with electric heater in cold places.

4.5 The temperature is lower than the area of zero ℃in winter, the feedwater pipe of the evaporating condenser must wrap up the heat insulation material, in case that the pipeline stops up or freezes to crack, one should install the electric heater additionally in the possible and frozen place in wa
