HOW IT WORKS ?

An earth-air heat exchanger (EAHX) is a surface geothermic solution for buildings, made by a buried pipe system circulating fresh air. It aims at warming up fresh air in buildings in winter and cooling it down in summer. Based on thermal air-ground exchanges, it is a passive solution. Where installed, the earth-air heat exchanger takes an active part in the thermal comfort within the building. ELIXAIR®by PAM is a comprehensive offer, designed to build earth-air EAHX combining safety and efficiency with ductile iron products.

MAJOR BENEFITS

- System under French Technical Approval 14/14-2056 CSTB

- Energy-savings thanks to the complete system and the high thermal conductivity of ductile iron

- Resistance to grounds and traffic loads : ductile iron pipe systems can be buried deep without damage, also under driven areas or parking lots

- Withstand rustic laying conditions allowing backfill with the extracted materials

- Excellent air tightness due to Express or Standard couplings working under compression

- Durability: as for all buried systems, strength and long lasting properties are key factors to avoid premature replacements.
