HOW IT WORKS
The KeepTheHeat system works by forcing fresh air at into a system of corrugated tubing encased in a 20 ft. ventilation duct. Fresh air tubing is routed down the walls to provide a clean breathing zone of air.
As the incoming fresh air is flowing into the building through the corrugated tubing, the exhaust fan pulls the internal contaminated air into the end of the ventilation duct (this is the same section that the corrugated tubing exits the duct). The exhaust fan draws this contaminated air across the corrugated tubing and then blows it outside the building.
This contaminated air, taken from the ceiling level at 1,500 CFM, warms the corrugated tubing, which then in turn warms the incoming fresh air flowing inside of the tubing. This is how the KeepTheHeat system functions as a heat exchanger. It uses the heat that is already present inside of your facility and transfers it to the fresh air coming in from outside. Think of it like heat recycling.
The Distinctive Y-Shape Design
Fresh air is brought into the building at the top of system using a turbine fan. The undesirable vapors are pulled out through the bottom of the system with a second fan. All components are designed for long life and low maintenance. The only parts of the system that move are the fans. These systems can be used year round. The motors are 1 horse power and can be wired for 110 or 220 volt single phase or 208-230/460 three phase. System is designed to move 1,500 CFM.
Design is the Key
The combination of tubes within a duct, correctly calculated heat-transfer area, and turbulent air flow within the unit provides the highly efficient heat transfer. Supplying the fresh air to the floor level and exhausting air at the ceiling level gives us an upward airflow pattern. This keeps the breathing zone of the facility continually supplied with fresh air while pushing contaminated air to the ceiling. This airflow pattern can be reversed depending on the application (humidity, heavy fumes, CO2). In these applications, supply air is delivered at the ceiling while exhaust air is removed at the floor.
