Series HRP Packaged Heat Recovery using Engineered Air QDT HEAT PIPE systems


Custom manufacturing facilities again play a major role in allowing us to incorporate our Heat Pipe coils into all of our HVAC equipment. The use of an Engineered Air heat pipe coil reduces cooling and heating loads through non mechanical technology. Our exclusive wicking procedure insures maximum heat transfer when you need it most. When packaged with our state of the art Q-TRAC controller we can offer maximum summer cooling load reduction combined with winter time heat recovery.

QDT has developed a world wide reputation as the most advanced and reliable source for heat pipe energy recovery systems. Our attention to system efficiency combined with our state of the art manufacturing facilities, ensure that you achieve all of your heat recovery expectations

Our QDT Heat Pipes division offers a comprehensive line of energy recovery equipment. The twenty first century presents us with the challenge of eliminating greenhouse gasses and reducing over-all energy consumption. The QDT product offering is a leap into the twenty first century by utilizing our innovative passive energy recovery systems. If energy conservation is your goal, QDT Heat Pipes offers you what you have been looking for.

HVAC Thermal Recovery Units

The QDT line of HVAC Thermal Recovery units are founded on our Air-to-Air Heat Pipe technology. Our state of the art Heat Pipe system utilizes our proprietary wicking method to ensure maximum thermal recovery in your system. By passing heated or cooled exhaust air across a portion of the heat pipe we are able to recover much of your buildings comfort costs. The process of thermal recovery is achieved by the passive evaporation and condensation of gases with a net saving in your energy usage.



Integrated Tilt Package

The addition of a QDT integrated tilt package allows you complete control over the thermal recovery process. The ability to change the tilt angle of the heat pipe allows for maximum recovery on peak demand days, summer/winter change over, and frost protection in severe climates.



Indirect Evaporative Coolers

Summer time cooling system recovery can be enhanced through the addition of an evaporative pad. By placing the evaporative pad in the exhaust air stream we are able to reduce the temperature of the exhaust passing across the Heat Pipe coil. This allows the pipe to accept more heat from the incoming ambient air reducing the supply air temperature to the building.



Industrial Thermal Recovery Units

Industrial plants exhaust large amounts of valuable heat that in many cases is contaminated with pollutants. The addition of a QDT thermal recovery package allows this heat to be recovered without compromising the integrity of the make-up air stream. If you are exhausting at high temperature and paying to heat your make-up air, QDT heat pipes offers you an energy and cost savings opportunity.



Wrap-Around Heat Pipes

Wrap-Around heat pipes offer substantial savings on dehumidification systems by pre-cooling air before it enters the evaporator and transferring the heat to the cold, dehumidified air. You receive a double savings by reducing the cooling load and the reheat load.
