Keep More Heat™ Air-to-Air Heat Exchanger - What does it do?

The Keep More Heat™ system works by forcing clean air from the outside into a system of corrugated tubing. This tubing runs through a 20 ft. ventilation duct, exits the duct work, and is routed along the ceiling and then down the walls or pillars to floor level. As the incoming fresh air is flowing into the building through the corrugated tubes, an exhaust fan pulls the internal stagnat or contaminated air into the open end of the ventilation duct (this is the same section that the corrugated tubing exits the ventilation duct) , and draws this "bad" air across the corrugated tubing which is then exhausted outside the building. This "bad" air, taken from the ceiling level, warms the corrugated tubing, which then in turn warms the incoming fresh air flowing inside of the tubing. This is how the Keep More Heat™ system functions as a heat exchanger. It uses the heat that is already present inside of your facility to heat the fresh air coming in from outside. Another way to look at it is heat recycling.


The Distinctive Y-Shape Design - Fresh air is brought into the building at the top of "Y" using a turbine fan. The undesirable vapors are pulled through the bottom of the "Y" with a second fan. All components are designed for long life and low maintenance. The only parts of the unit that move are the fans. These units can be used year round to keep your work area cooler in the summer by only using the exhausting fan.


Design is the key. The combination of tubes within tubes, correctly calculated heat-transfer area, and turbulent air flow within the unit provides the highly efficient heat transfer. The outside air is heated to within 5º F. to 10º F. of the inside air and is often even warmer than the air at floor level in your shop. (Please check your local and Federal requirements regarding air emissions.) As fumes or exhausts rise, the heat exchanger creates a draft at the ceiling level and draws the fumes outside. As the heat exchanger draws your contaminated building air out, it uses this heat to warm the incoming air. As you know, when the black smoke or contaminated air created in your building starts to cool off and starts coming down, it is much harder to remove. Our system removes this contaminated air before it starts to cool and conserves energy in the process.
