PROJECT HISTORY

In June of 1998, a THERMO-CYCLER® Gas Fired Heating System consisting of one (1) Thermo-Cycler GTC-400 heating unit was chosen as the preferred heating system for the new machine shop facility. This facility also utilizes recirculating air cleaning equipment to control welding smoke. In addition to greatly improved employee comfort, the new facility has over double the area, triple the volume, but cost approximately 25% less to heat than the old facility despite a gas price increase of 7.2%. Based on fuel cost adjusted square footage, the new pre-engineered building using a Thermo-Cycler was heated for approximately 1/3 the cost of the old facility that was heated with ceiling mounted unit heaters.
