Model "D" Fre-Heater®

Model "D" Fre-Heater®

Capture Lost Heat

Whether your processing operation is large or small, you need plenty of hot water for various purposes. The Mueller Fre-Heater recovers wasted heat from your milk cooler's condensing unit and uses it to heat water you can use. Adding a Fre-Heater to your processing operation will drastically reduce the cost of hot water, thereby lowering your cost of production and enhancing your profitability.


Durable. Dependable. Reliable.

A Model D Fre-Heater consists of a heavy-duty, glass-lined storage tank surrounded by our stainless steel Temp-PlateĀ® heat transfer surface for maximum heating efficiency. Two-inch foam surrounds the Temp-Plate surface, keeping heat within the tank. A rust-resistant, stainless steel outer jacket houses the entire assembly for protection and appearance. Model D recovers up to 60 percent of your system's wasted heat energy. It is available in sizes from 50 to 120 gallons to meet your specific hot water needs.
