Benefits


  • Regenerative, non-hygroscopic, aluminium rotating heat exchanger located in the centre of the unit.
  • Low energy, high performance EC fans
  • Up to 86% heat recovery efficiency
  • Large surface Pollen Grade F7 filter (inlet and outlet) is the highest specification available for any residential ventilation system
  • Increases thermal comfort by heat recovery or night cooling recovery
  • Low sound level
  • Constructed in Galvanized and Aluzinc Steel
  • Insulated with 50mm dense mineral wool for quietness and facilitates use in any warm or cold space
  • No condensate drain required
  • Use of commercial smoothflow rigid ducting throughout. Low pressure loss means low energy use.  Higher heat efficiency. Quieter (due to low velocity). Ducting can be cleaned & maintained.  Resists crush damage during construction and thereafter. Lifetime installation.
  • Precision engineered fittings. Only precision fit metal and plastic fittings, ducting and silencers, along with Grade 1 duct installation are professionally installed throughout.

A key aspect of a well planned, low energy MVHR system is the ducting type, design and the quality of installation.

  • Best practice is to use larger diameter, 125mm diameter branch lines and up to 250mm diameter main lines, which can carry the necessary high volumes of air at low velocity (depending on size of system).
  • Rigid, large diameter ducting is the preferred choice to provide a smooth flow of air, causing less noise (from both fans and air turbulence) and costs less to run. Foil backed insulated ducting in a cold space is essential to retain high heat efficiency.
  • Carefully considering the design and choice of installation materials ensures your MVHR system delivers the correct ventilation rate and heat efficiency to your home.
  • Manufactured in high quality steel our modern Supply & Extract Valves are designed to not produce down draft, ensuring a comfortable indoor climate.
