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 a slow rotating wheel. 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 as a stand-alone unit for use in applications requiring maximum energy efficiency in a make-up air unit, up to 100% outside air.
- Sizes 300 – 12,000 CFM of outdoor air mixed with return air or up to 100% 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
- 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
- AirXchange ARI 1060 certified energy recovery wheels are used and carry a 5 year limited warranty
- The wheel desiccant material is permanently integrated into the media of the wheel
- The energy recover cassette is a UL® recognized component for electrical and fire safety
- Available with enthalpy or sensible only wheel for a variety of applications
- Available in downflow, over/under and side-by-side configurations
- Epoxy powder paint finish to withstand outdoor environments
- Centrifugal belt-driven forward-curved blowers with adjustable pulleys and isolation pads
- High efficiency motors are thermally protected
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
- All wheels are designed to easily slide in and out of the ERV for servicing
- Continuous operation down to 10°F (-12°C) without defrost at indoor relative humidity up to 40%
- For temperatures below 10°F (-12°C), Optional Low Ambient Control Kit is required.
