New REHAU ECOAIR' Ground-Air Heat Exchange System Reduces Heating & Cooling Costs

The REHAU ECOAIR' system improves indoor air quality by bringing necessary fresh air into today's tighter building envelopes. Narrowing the gap between outdoor temperatures and comfortable indoor temperatures, it significantly reduces the amount of additional energy required for heating or cooling.

REHAU announced its recent partnership with Agion Technologies, the worldwide leader in natural silver-based antimicrobial solutions, to incorporate Agion's antimicrobial technology into the new REHAU ECOAIR' ground-air heat exchange system.

The REHAU ECOAIR system takes advantage of consistently moderate ground temperatures to pre-condition incoming fresh air, thus improving indoor air ventilation while also reducing heating and cooling costs. It is comprised of an air inlet, filtering and condensation management components, and rigid PVC pipe and fittings which are protected by Agion.

The system's smooth-walled PVC pipe features a unique inner layer developed by Agion that capitalizes on the naturally occurring properties of silver to inhibit microbial growth. Agion's silver antimicrobial has been tested and verified by SGS Institut Fresenius in Taunusstein, Germany to ASTM Standard E2180, and is also registered with the EPA for use as an antimicrobial in HVAC applications.

"Our partnership with REHAU has resulted in the launch of a state-of-the-art HVAC system that combines energy-efficient operation with natural antimicrobial protection," said Paul Ford, CEO of Agion Technologies. "With green building initiatives at the forefront of the industry, Agion has become the preferred antimicrobial of HVAC manufacturers."

"As a result of condensation during the cooling season, the typically moist environment in a ground-air heat exchange system's pipe can be conducive to microbial growth," said Scott Emery, business unit manager, civil engineering and infrastructure at REHAU. "Thus, in addition to allowing for condensate drainage and inlet-air filtration, we have partnered with Agion to incorporate a unique formula that includes silver particles, which are a natural inhibitor to such growth, into the inner layer of the REHAU ECOAIR pipe. Our work with Agion has fostered a unique solution in ground-air heat exchange that delivers controlled ventilation while providing notable HVAC system energy savings."

The REHAU ECOAIR system improves indoor air quality by bringing necessary fresh air into today's tighter, more energy-efficient residential and commercial building envelopes. By narrowing the gap between outdoor temperatures and comfortable indoor temperatures, a ground-air heat exchange system significantly reduces the amount of additional energy required to heat or cool a building. It is in fact possible for a ground-air heat exchange system to assist in raising intake air temperature by up to 16°F (9°C) during colder months, and reducing it by up to 29°F (16°C) in the summer.

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
