The Solution
lets you enjoy the fresh-air feel of
an open window, with v irtual ly
little or no heat or energy loss. È Replace stale, pol luted indoor air with
fresher, healthier and oxygen rich outside air.
È Ideal for tightly sealed new commercial
buildings and modern homes.
È Compact unit size allows it to be retro-
fitted with your existing air-conditioning
system to enhance the indoor air quality.
How does it work ? The heart of the Energy Recovery Ventilator
is the EcoFresh des iccant coated energy
r ecove ry whee l , wh i ch s l o w l y r o t a t e s
between its two sections. In one section,
the stale, conditioned air is passed through
t h e w h e e l , a n d e x h a u s t e d t o t h e
a t m o s p h e r e . D u r i n g t h i s p r o c e s s , t h e
wheel absorbs sensib le and latent energy
f rom the cond i t i oned a i r , wh ich i s used
to pre-condit ion the incoming Fresh Air in
the other section, during the second half
of i ts rotat ion cycle. Thus, you can have
more Fresh Air at lower energy costs inside
your conditioned space.
