Energy Recovery

Rotary heat exchanger as built by Heatex (1) allows for high efficiencies both sensible and latent and provides a fast return on investment. The airflows can be oriented side by side or top/bottom and the complete exchanger can be put in a vertical as well as in a horizontal position. Wheels available from small to large applications. Selections with performance are available upon request. Air leakage between wheel and casing is minimized by a brush sealant. For even better wear resistance and tightness, a special polymer sealing solution is available as option. The unit is available with a purge sector to minimize the cross contamination of exhaust air into the fresh air.

Air to Air Crossflow heatexchangers as built by Heatex (1) are available as standard with Aluminum and aluminum with epoxy coating. Plate frame heatexchangers offer low to no maintenance with similar efficiencies as other technologies. Special coatings are available and leakage rates are very low compared to most technologies.

Heat Pipe Technology products are a completely Passive Energy Recovery Solution with No Moving Parts, No Compressors, Pumps, Pulleys, Belts or Motors.

Heat Pipes offer a Zero Cross Contamination Energy Recovery Solution between the Exhaust and Supply Air Streams.

Heat Pipes are a maintenance free and worry-free solution that will last for the entire life of your Air Handling Unit from Unitech.

Heat Pipes are up to 55% effective and can fit into any size custom air handler with fin lengths up to 20 feet and fin heights that can be as tall as you need them to be, as they are stackable.

Evaporative cooling modules can be factory installed upstream of the exhaust air heat recovery media. The evaporative cooling module does not come in direct contact with the recovery media thus not deteriorating the recovery media. This allows for far greater efficiencies as compared to the same recovery media without the pre evaporative cooling module.

Unitech specializes in designing and building custom commercial Evaporative cooling modules. Unitech standard product is built with Munters (3) media. Unitech designs and builds a complete system including re-circulation pumps, washdown systems and sumps with drains. The Evaporative section sump and casing is built of stainless steel construction and copper piping.
