Material characteristics

Aluminium (AL)

The condensation wheel allows moisture transfer when, in winter conditions, the extract air falls below its dew temperature. It's the most economically advantageous solution to recover heat in most applications.

Hybrid (AT)

The hybrid enthalpic wheel allows the sensible and latent recovery due its hygroscopic matrix, that allows the moisture exchange between the supply and exhaust side.

Sorption (AR, AZ)

The adsorbent silica gel treatment (AR) which is applied to the aluminium layer, this allows the recvoery of the sensible and latent heat, reaching very high efficiency values, ensuring considerable energy savings. Also available in the version with hygroscopic coating based on molecular sieve 3Å (AZ), highly performing

Epoxy anticorrosion (AC)

In enviroments with aggressive atmosphere, it is recommended that the aluminium is protected by a paint coating non-toxic based and epoxy corrosion resistant (AC version - GOLD).

TREATMENT	AL Condensation The condensing wheel allows the transfer of moisture when, in winter conditions, the ejection current falls below its dew point. It is the most cost-effective solution for recovering heat in most applications.
	AT Hybrid The hybrid enthalpy wheel allows thermal recovery both latent and sensitive thanks to the hygroscopic matrix that allows the exchange of humidity between the expulsion current and the renewal one.
	AZ Sorption - Molecular sieve 3Å The adsorbent treatment, also available in the version with hygroscopic coating based on molecular sieve 3Ä (AZ), highly performing.
