Project: HVAC Renovation
Start Date: 11/1/03 Completion Date: 3/1/04


The Automotive Industry is constantly changing vehicle design to better suit consumer needs. These changes require modern machinery and tooling centers in order to meet the overwhelming need for quality products at low operating cost.

TMI’s ability to take existing HVAC equipment and remanufacture it in the field to the latest specifications has been extremely successful. TMI was able to de-construct the existing equipment to a point which only left the sheet metal shell of the unit. TMI was then able to install the following equipment

Intake dampers and return air dampers
Torrit Filter System with controls
Face and bypass steam coils
Direct fired burner gas train and flame safty controls
Supply fan and motor on spring isolation
PLC controls temperature controls and Motor Controls
Exhaust fan start panels with interlock.

Upon completion of start-up and commissioning, the units were running more efficiently and TMI was able to maintain building temperature by only running half of the units refurbished. The cost savings will be recognized for years to come.
