Product Overview, Models and Capacities

Product Overview

This unit brings in fresh, outdoor air and removes stale exhaust air from the building. The intake and exhaust airstreams move through the unit in opposite directions in separate passages, and each airstream passes through an energy wheel. In cooling mode, the energy wheel removes both heat and moisture from the incoming airstream and rejects it into the exhaust airstream. In heating mode, the energy wheel removes heat and humidity from the exhaust air and rejects

it into the intake air, thus reclaiming energy already expended to heat the building air.

In addition to the energy wheel, this unit incorporates a packaged water source heat pump The heat pump system comes from the factory fully-charged with refrigerant and is ready for connection to a water source upon arrival.

For purposes of providing temporary emergency heat, an optional secondary heating source such as indirect gas furnace or electric heaters may also be installed.

The smaller tonnage units (4-6 tons) contain a single compressor, allowing for one stage of cooling. Larger units (8-30 tons) come standard with two compressors and a split airside coil. This allows for staging of compressors to meet a wider range of outdoor air loads while reducing the amount of cycles per compressor.

Simply put, this unit preconditions the outdoor air to save money on heating and cooling costs and then provides supplemental heating and cooling by means of a highly efficient heat pump.

Models and Capacities

This unit is manufactured in four different platform sizes; 20, 45, 55 and 90. Each platform has multiple options for heating and cooling capacities.

All 4, 5 and 6 ton capacity units have a single scroll type compressor and all other units have two scroll type compressors and use a split airside heat pump coil.
