Model D Fre-Heater

Fre-Heater® Heat Recovery Systems

A Paul Mueller Company Fre-Heater can recover up to 60 percent of wasted energy normally discarded from refrigeration and air-conditioning systems. By transferring the recovered heat energy to water, vast amounts of free hot water can be stored for use when and where the need arises.

Mueller Temp-Plate® is the heart of the Fre-Heater system. This highly efficient heat transfer surface is constructed of 100 percent stainless steel. Thoroughly tested and listed by CSA US and Canada, it meets all codes required for double-wall heat exchanger construction. Canadian Registration Numbers (CRNs) are also available.

Mueller Fre-Heater’s industrial-grade, glass-lined water storage tank resists rust and features two replaceable magnesium anodes for extra protection against natural water corrosion, increasing the life of the tank. A Fre-Heater heats and stores in one unit, plus it operates on any potable water supply because it is virtually immune to corrosion.

Walk-in coolers, freezers, commercial air-conditioning systems, ice machines, and other refrigeration systems all waste enough heat energy to produce hot water on a large scale. A Mueller Fre-Heater pays for itself while reducing your energy costs proportionately to your hot water usage.
