Aquefier Desuperheaters for Domestic and Industrial Use

The DOUCETTE AC and Aquefier Series Substantially Reduces Your Hot Water Heating Costs



  • Heats potable water up to 60°C using waste heat
  • Typical Payback Period of Two Years or Less
  • Reduces A/C operating costs 5% to 15%
  • Mechanical Cleanable Counterflow Design
  • Compact and Ready to Install
  • Works with All Major Manufacturers’ Systems

The DOUCETTE AC and Aquefier Series™ heat recovery units deliver substantial energy savings by heating potable water by recovering waste heat from refrigeration air conditioning, chiller and heat pump systems. The AC Series™ can effectively heat water up to 60°C, and is ideal for systems ranging from 5 – 200 HP using reciprocating, rotary and screw compressors.

The unit arrives as a standard factory package that is ready to install, and can be applied to both air- and water-cooled systems using R-404a, R-507, R-22 and other refrigerants.

Improve A/C System Operation

Installation of a DOUCETTE Series™ heat recovery unit into your existing cooling configuration is equivalent to adding 15% more condenser capacity. The result is a 5% to 10% reduction in reduced air conditioning operating costs, enhanced air conditioner performance and prolonged operational life.

Vented Double Wall for Safety

The DOUCETTE AC and Aquefier Series heat exchanger tubes are designed with patented vented double-wall copper or 316 stainless steel construction for an added measure of safety and reliability. The double-wall system prevents contamination of the potable water from the refrigeration circuit. Each tube is fluted such that a vent path is created between the outer and inner tube. If a tube leak should ever occur, the gas vents to the atmosphere for easy detection. This double protection system meets all national, state, local and provincial health and plumbing codes requiring double separation and cross connection safety requirements.
