A Mueller Fre-Heater© recovers the wasted heat from your milk cooler’s refrigeration unit and uses it to produce hot water that you can use for all your equipment cleaning needs. Three models of Fre-Heaters are available: the Model “D”, “DE”, and Tri-Plate©.

The “D” and “DE” can recover up to 60 percent of your condenser’s wasted heat. The Tri-Plate recovers 100 percent of wasted heat and produces extra-large volumes of hot water. Fre-Heaters are available in 50, 80, and 120 gallon sizes (189, 302, and 454 liters).
