DFE Fre-Heaters

Convert Wasted Heat into Free Hot Water with a Fre-Heater®!

Whether your dairy farm operation is large or small, you need plenty of hot water for equipment cleanup, cow prepping, and feeding calves. What better way is there to meet your everyday needs than with free hot water? The Mueller Fre-Heater recovers wasted heat from your milk cooler's condensing unit and uses it to heat water you can use for feeding calves and cleaning. Adding a Fre-Heater to your milk cooling system will drastically reduce the cost of hot water in your operation, thereby lowering your cost of production and enhancing your profitability.


Fre-Heater Model D

A Model D Fre-Heater consists of a heavy-duty, glass-lined storage tank surrounded by our stainless steel Temp-Plate® 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.


Fre-Heater Model DE

Model DE is similar in construction to the Model D, and it also automatically recovers up to 60 percent of your system's wasted heat. A 4.5 kW heating element, however, is included for maintaining 120° to 170°F water. Model DE is available in 80- and 120-gallon sizes. The 120-gallon unit may be supplied with an optional 6 kW heating element for faster heat recovery.
