E-Z vent residential air-to-air heat exchanger system consists of one supply fan, one exhaust fan and a Z-Duct plate type heat exchanger module all contained in a corrosion resistant galvanized metal housing.
The heat exchanger consists of a continuous, die formed embossed and folded sheet of 1100-0 aluminum to form two separate flow passages on both sides of the aluminum sheet metal. This construction method permits the two air streams to be in close proximity, separated only by the aluminum sheet metal. Efficiency is between 78 to 92%. I believe this unit is more efficient than my replacement unit which uses plastic instead of aluminum in the exchanger core.
This unit was taken out of service only because the bottom was rusting through. It can be repaired by spraying a rubberized material to inside/outside or replacing bottom of unit with galvanized metal or aluminum. I upgraded to new unit--not sure if it was an upgrade or downgrade. My new unit is programmable.
I have instruction and service manual. I had this unit on a timer which worked very well. Replaced bearings in both motors over the years plus have one set of bearing for one motor when needed. Also comes with copper plumbing for condensate drain and hanger materials.
Unit should give many more years of service when repaired or use as is. Bottom leaks condensate.
Will repair for additional money.
