Rx (ERV) ModuleRx (ERV) Module

The energy recovery wheel inside the ERV unit transfers energy from the warmer to the cooler air stream through counter-flowing supply and exhaust air streams through the slowly rotating wheel (less than 60 revolutions per minute). The large energy transfer surface arranged to provide laminar air flow through the wheel causes the constant flow of recovered energy to represent up to 80% of the difference in total energy contained within the two air streams. The Rx (ERV) Series is designed to be mated to the TRE Series rooftop unit for maximum energy efficiency in a make-up air unit, up to 100% outside air.

  • Sizes 1000 through 10,000 CFM of outdoor air mixed with return air or up to 100% outside air
  • All of the features of the TRE Series PLUS energy recovery
  • 20+ (Combined) EER substantially reduces the cost of preconditioning outside air
  • Avoids using large gas makeup air units and complicated refrigeration controls to handle outside air
  • Simple operation facilitates ease of maintenance and troubleshooting
  • Allows the designer to provide water-source equipment for all HVAC needs
  • Decreases building equipment tonnage required, which reduces installation costs
  • Can cut loop costs up to 50% for ground loop (geothermal) applications by reducing equipment tonnage required
  • Uses AHRI-1060 rated wheel technology
  • Available with silica gel or molecular sieve wheel
  • Available in stand alone, curb mounted & integrated, or mounted to rooftop unit (TRE Accessory Module)
  • Finish matches TRE Series rooftop
  • Optional factory-installed pre-heater available
  • Hinged panels at all service entries
  • Centrifugal belt-driven forward-curved blowers with adjustable pulleys and isolation pads. High efficiency motors are thermally protected
  • Easy access controls with optional ERV
    fault indicators. A simple, quick connecting Molex connector ties ERV controls to TRE Series rooftop unit controls
  • 2" pleated pre-filters for outside air with 2" pleated filters on exhaust air help keep the wheel clean. Up to Merv 13 filter compatible
  • Heavy duty base rails for easy lifting and rigging
  • Hinged access doors with 1/4 turn g-loaded latches
  • Exhaust and supply air streams have back-draft dampers to prevent air penetration during
    off cycles
  • The energy recovery wheel transfers energy from the warmer to cooler air streams at a nominal up to 80% efficiency and is AHRI-1060 certified
  • Slide out wheel assembly makes cleaning and maintenance easy
