We first base our analysis that almost all sites operate within a negative building air balance.  Simply put, the building is inviting outside ambient air in either through the building envelope or any mechanical means such as exhaust fans.  How can we tell?  By opening an outside door, is there a breeze into the building?  Or is there a breeze while standing in an open doorway between your office space and your warehouse?  The stronger the breeze, the greater the negative air balance within the building. These are some indications that during the winter heating season, the outside cold air is being “asked” to infiltrate the building causing the building heating system to have to work much harder and consume more energy to warm that new cold permeating air. 

Our system works with that principle.  We draw in outside ambient air; heat it up with your current unwanted warm/hot liquid stream that may currently be targeted for a cooling tower, chiller or any other heat dissipating method.  At first blush, this may seem counter intuitive.  However, by taking outside air, warming it with waste heat the facility has already paid for and is seeking to rid itself of, we are now introducing into the facility a warmer positive pressure that the current heating system will not have to work so hard to overcome.  The overall goal is to inject the facility with warmer air than what is currently trying to permeate the building.  The plant winter heat load can be substantially lowered which results in a significant cost savings. 

In summary, in addition to the heated air forced back into the building, the building air balance is raised lowering the rate of cold winter air infiltration.  And third, this process will also then reduce the current work load on the process cooling system due to the extraction of the BTU's from the process fluid.  All of these measures add up in saving your site considerable energy dollars.
