Model D Fre-Heater®

---

No matter the size of your dairy operation, you need ample hot water. With the Mueller Fre-Heater® you can capture the heat from the milk and inject it back into your potable hot water system. Depending on your dairy cooling system and the amount of your dairy production, 100 percent of your hot water needs can be supplied by a Fre-Heater. 

Through these systems Mueller encourages sustainability by recycling the heat generated from the tank-cleaning process and using it to fill the hot water heater.

With our dual jacket, there are no concerns about refrigerant leakage and our industrial-grade, fully-insulated, glass-lined storage tank assures potable water and minimal heat loss.

• Stainless steel outer jacket. Rust resistant exterior requires no maintenance.
• Mueller Temp-Plate heat transfer surface cools the super-heated refrigerant from the milk cooling condensing units and harvests the system’s wasted heat energy.
• Industrial-grade, fully insulated, glass-lined storage tank assures minimal heat loss and long-term reliability.
• Factory-installed anode(s) provides superior galvanic corrosion protection for the water storage tank. Model D-120 has 2 anodes, and Models D-50 and D-80 each have 1 anode.
• Five-year limited warranty protects your purchase.
• Complies with CSA regulations for the United States and Canada.
