Fre-Heaters encourage sustainability in your dairy farm operation by recycling the heat generated from the tank-cleaning process and using it to fill the hot water heater. This model includes an electric heating element to support the heating process if high quantities of hot water are needed.
Differentiator: Dual Jacket (If refrigerant leaks, the water is still potable.)

*Refrigeration tonnage capacities are 30°F evaporator ton loads, not total heat of rejection tons. Pressure drop through a Fre-Heater refrigeration circuit will be approximately 15 psi at the maximum tonnage application. Pressure drop at the mid-range of tonnage application will be approximately 5 to 7 psi. The best overall refrigeration/heat recovery system efficiency is usually obtained at or below the mid-range tonnage application.
