WRG Boiler
The energy released during the cooling process is supplied to the water by the Lister-heat recovery system via a heat exchanger. If the water temperature of about 55-60 ° C is reached, a pressure switch will switch the cooling system to normal operation. It is guaranteed that the cooling system continues to operate under normal conditions.
The amount of hot water and the heat recovery basically depend on the quantity of milk. From 100 liters of milk to be cooled from about 35 ° C. to 4 ° C. about 70 liters of water can be heated from about 12 ° C to 55 ° C. The heated water can be used to clean the milking machine, the milk cooling tank, to heat the milk for calves, as well as for kitchen and bathroom.
If desired, the heat recovery system can be fitted with an additional heating. This additional heating is used to bridge periods of low milk or reheat the existing hot water from about 55-60 ° C up to 80 ° C.
