One important factor in the longevity of UNITECH's custom-built, high quality HVAC equipment is our tough coating system . . . the finest on the market for commercial and industrial equipment. Following lengthy development and research, our coatings have been uniquely formulated to withstand years of exposure under the most adverse weather conditions without deterioration. They have been extensively tested under a wide variety of conditions to ensure that owners of UNITECH units receive the best value for their investment.

All UNITECH units - including air handlers and compressorized systems are designed for either indoor or outdoor installation - are coated with our outstanding powder coat finish.

The exterior panels are minimum 16 gauge galvanized steel sheets continuously hot dip-coated with a durable protective coating of zinc. Panels are then sprayed with a heated phosphoric acid to remove all oil and other impurities and treated with a specially formulated chrome rinse. This ensures that the finish coat adheres properly. A corrosion-resistant urethane primer is immediately applied on both the tip and reverse sides before any oxidation can occur.

The primary finish coat is applied in a color of the customers choice. It is applied on both sides and the entire coating system is baked on for even better adhesion.
