  • Unique design temperature controlled summer bypass in conjunction with Summerboost will increase the fresh air supply and extraction rates up to 40% more than the set boost rate.
  • G4 filters as standard. Low cost filter refills available, saving waste and cost.
  • Intelligent frost protection - built-in to prevent freezing.
  • Internally insulated in high density Expandable Polypropylene (EPP) - allows unit to be installed in any location within the home where temperature ranges from -5 to +40oC.
  • Manufactured in durable Zintec® steel complete with high gloss baked resin finish for long life.

Best Practice MVHR Installation 

All systems are designed in-house by our experienced technical team and installed by our own team of BPEC registered engineers.

Our Mechanical Ventilation with Heat Recovery (MVHR) systems are installed with smoothflow rigid ducting throughout, providing higher heat efficiency. The resulting low pressure loss will mean a lower energy use and the system will be quieter due to efficient low velocity.

This solid ducting is resistant to crush damage during construction and thereafter can be cleaned and maintained if required.

We only use precision engineered metal and plastic fittings, ducting and silencers mechanically fastened and sealed at every joint.

MVHR Ducting Installation should take place as follows:

If the house is of concrete slab construction

  • When roof is complete (building watertight)
  • Before any other services are installed below the concrete slab
  • A void space of 200mm below the concrete slab will allow insulated duct to be used
  • A void space of 100mm will mean you will have to convert to 204/60mm flat channel ducting

If the house is of timber-frame construction

  •  When roof is complete (building watertight)
  • Before any other services are installed
  • Timber partition walls and floors are in place

Should you decide to install a MVHR system from Beam on a DIY basis, we can provide design layout and commissioning. However, it is crucial that best practice is adhered to at all times to ensure system efficiency.

Aura-T®

Aura-T® is a simple touchscreen controller for programming, set-up and occupancy control from the Beam Axco C130 & C170. Connected to the MVHR System via a wired connection, typically located in a central location, it allows straightforward operation of ventilation speeds at the touch of a screen. 

  • Digital 4 speed switch
  • 7 day programmable timer
  • Filter change indicator
  • Internal MVHR humidity sensor
  • Boost inhibit function
  • Kitchen and wet rooms overrun timer
  • Real time status and operating mode 

Auralite®

Auralite® is a low voltage hard wired remote LED ventilation system status indicator, designed to fit a standard UK patress or recessed backbox.  The indicator is for use with Axco C Range models C50, C75 and C100 and displays:

  • Normal Running - the system is running at continous speed (normal mode) or the unit is running at setback speed if this light is flashing 
  • Frost Protection - the unit is in automatic frost protection mode
  • Filter Change - the filters require changing 
  • Boost Speed - the system is running in boost speed if this light is flashing 
  • Summer - the is in summer bypass mode
  • Fault - there is a fault with the system and the installer should be contacted 
 

Features and Benefits

  • Meets guidlines for owner accessability 
  • Increase owner awareness of system operation 
  • Can be sited remotely from unit in an easy to access location 
  • Discreet design 
  • Fits a standard UK patress box 
  • Compatible with Titon HRV units  

One of the most important aspects of a well planned, low energy MVHR system is the ducting type, design and the quality of installation.

The 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.

Careful consideration to the design and choice of installation materials ensures your MVHR system delivers the correct ventilation rate and heat efficiency to your home.

Our modern Supply & Extract Valves are manufacture in high quality steel and are designed to not produce down draft, ensuring a comfortable indoor climate.
