Polynum Ultra

A patented multi pure aluminium foils incorporated onto double 8mm thermo cellular (Fire Retardant) polyethylene bubbles, with a unique internal reflection mechanism in each bubbles structure, with high performance copper aluminium foil on top side, and silver aluminium foil on bottom side. Optional: 18 microns aluminium and reinforced net.

Both, external and internal aluminium surfaces with and without copper antiglare, reflecting 95% and 97% of radiant heat respectively. PolynumTM Ultra products are made of a unique Foil-bubbles-Foil-bubbles-Foil structure providing a built-in HIR (High Internal Reflection) with the aim to minimizing Radiation, Conduction and Convection heat transfer. PolynumTM products are easy to transport, store, handle and install. PolynumTM superb thermal performances against heat flow provide excellent energy efficient solutions. PolynumTM comply with mandatory Australian Standards and Building CodeofAustraliacertificationbenchmarks.PolynumTM productshavebeen certified by Ecospecifier and are engineered to comply with the ABGR and Green Star Rating Scheme.

Comfort & protection for your home

The AiroMatic is Edmonds latest powered roof top ventilator, developed to meet the cooling and drying needs of residential homes. It is a dual purpose ventilator, which can be used to cool a roof space on hot days via its new temperature sensing inverter speed control technology, or it can be set for constant ventilation rates to help reduce condensation build up in the roof space.

The AiroMatic is the first of Edmonds range of ventilators developed using advanced CFD (Computational Fluid Dynamics) software. It has allowed Edmonds to produce a ventilator with a higher flow rate and efficiency than other ventilators while reducing its overall noise level and physical size. The innovative German motor that powers the AiroMatic, incorporates new blade tip winglet technology, and electronic commutating motor technology to further improve ef ciency and reduce noise.

The unique Edmonds design speed controller allows the selection of three fixed speeds of low, medium and high. This allows just the right amount of ow to be set to suit the severity of the conditions.

Benefits:

• Cooler in Summer
• Reduces risk of condensation
• Improves energy efficiency of ducted air conditioning
• Automatic flow adjustment to your homes’ needs
• Easy and safe to install - No electrician required
• Inverter variable speed technology Quiet operation
• Clear dome adding light to attics
• Comes in 4 colours but can be easily painted to suit your roof colour

How does AiroMatic work?

Temperature Control - Cooling mode

Set to automatic the unit senses temperature and switches on at low speed when the roof space temperature reaches 30°C. As the temperature rises, the inverter technology used in the AiroMatic, proportionally increases speed until the maximum speed is reached at 45°C. This means that the fan is only drawing as much power as needed to keep the roof space cool.

One of the benefits of reducing roof space temperature is improving air conditioning ef ciency and reducing the cost of running them.

Condensation Control - Drying mode

Condensation can potentially cause mould, mildew and building damage. Using any of the three speed manual control settings, the AiroMatic can effectively draw fresh and dry air into the roof cavity, removing moisture and helping to protect your home and the health of your family.

Features:

• Manufactured from tough, injection moulded UV stable polymers, designed for Australia’s harsh conditions. Malleable ashing will suit all roof types.
• 24VDC high ef ciency electronic commutating German motor. Operating power consumption as low a 4W (low speed setting)
• High ow rates up to 650m3/h (high speed setting)
• Automatic temperature sensor control with manual flow rate settings for condensation control
• Operating noise levels as low as 35 dB(A).
