ZQYRA installation


The hybrid Model ZQYRA unit is specifically designed to deliver demand ventilation air in commercial / industrial building applications such as:

  • schools
  • fitness centers
  • churches
  • retail outlets
  • offices
  • theaters and more

The unit uses its unique heat pump technology and enthalpy wheel combination to condition the fresh air by capturing energy from the exhaust air stream. This methodology results in significant less energy usage for building ventilation. In addition, the unit's demand based ventilation control system with setup, test routines and fan speed control reduces the complexity normally associated with applying ventilation air systems to buildings.
