HRV 3 Q Plus - Enthalpy

Ultra energy efficient MVHR with Enthalpy Energy Recovery

For use in large dwellings

Suitable for larger dwellings, the HRV3 Q Plus continuously running whole-house ventilation unit with heat recovery gives cutting edge performance usually only associated with much larger and more costly products.

The combination of very low power consumption and a highly efficient heat exchanger is small enough to be easily incorporated into medium sized dwellings.

The counter flow enthalpy heat exchanger has a selectivepolymer membrane film to achieve low air leakage levelswhile providing moisture recovery from the exhaust air. These models are ideal for living areas with low humidity, avoiding frost build up at low temperatures, they also have an antimicrobial membrane and long life cycle.

The Eco versions offer a 100% airflow diverting SummerBypass. It also includes intelligent humidity options and can be fitted with the auralite® status indicator or the auramode®aurastat® or aura-tTM controllers.

Features & Benefits

  • Constant volume fans
  • Highly efficient enthalpy counter flow heat exchanger
  • Intelligent controller, quick and easy to commission
  • Fully adjustable boost overrun timer 0-60 minutes; can be used with non-latching (momentary) switches to prevent unit from being accidentally left in boost mode
  • Accepts 125mm or 150mm diameter ducting, no adaptors required
  • Independent fan adjustment
  • Intelligent automated control of summer bypass, frost protection and humidity functions
  • Setback facility to reduce ventilation where local regulations allow
  • Lightweight for easy handling
  • Volt free switching control
  • G3 filters as standard, G4 as an option
  • Re-usable plastic filter frame
  • Quick fix mounting bracket
  • Patented
  • Independent fan adjustment
  • Effective in reducing pollutants in the home and improving Indoor Air Quality (IAQ), therefore reducing the risk of Toxic Home Syndrome
