Factory Eurovent heat recovery wheel

Working Principle

Rotary heat exchanger is composed of alveolate heat wheel, case, drive system and sealing parts. The ex-
haust and outdoor air pass through half of the wheel separately, when the wheel rotates, the heat and mois-
ture are exchanged between the exhaust and outdoor air. The energy recovery efficiency is up to 70% to
90%.

Wheel Materials

The sensible heat wheel is made by aluminum foils
of 0.05mm thickness.
And the total heat wheel is made by aluminum foils
coated with 3A molecular sieve of 0.07mm thick-
ness.

Adhensive; aluminum foil;

moisture absorption coating

Silicon gel absorbs both moisture and odor by
capillarity.

Molecular sieve selectively absorbs moisture
and expels odor by molecular lattice.

Wheel Construction

1, The wheel of the rotary heat exchanger is made of alternating layers of
flat and corrugated aluminum foil to form the alveolate shape.

2, Various height of corrugation is available.

3, Flat surface ensures minimum leakage.

4, Interior spokes are used to mechanically bond the rotor’s laminations.
These are threaded at the hub and welded at the periphery.
