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.
RECOMMENDED USE
Public buildings
Commercial and industrial buildings
Farm buildings
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.
