How It Works

MSP®Technology Patented Dehumidification Technology

  1. Warm, humid incoming air flows through the first pass of the plate type air-to-air heat exchangers for pre-cooling and initial dehumidification. This is accomplished by regenerative thermal exchange with the cooler air that is leaving the heat exchanger. (see step 3)
    Advantage: Pre-cooling and dehumidification by regenerative thermal exchange are “free” and involve no additional equipment.
  2. Pre-cooled air then passes twice over conventional cooling coils for final cooling and dehumidification.
    Advantage: Pre-cooled and pre-dehumidified air can be treated much more efficiently, using smaller compressors that require as little as one-half the power.
  3. The cool, dehumidified air is then drawn back through the opposite side of the heat exchanger where it absorbs some heat from incoming air (see step 1) and continues on to the building’s HVAC system.
    Advantage: No heating coil—and no energy penalty—needed to reheat the dehumidified air before it enters the conditioned environment.
