Model EQ - Rotating Heat Exchangers

Product Info

Model EQ

Segmented rotary heat exchanger in casing

Model EQ is Heatex rotary heat exchanger Model EV in a galvanized steel casing. One of the greatest advantages with Model EQ is the ability of onsite assembly. This provides for lower transportation costs and facilitates onsite handling.

The casing comes standard with sides, top and bottom open. A fully covered casing is available as option. The unit can be delivered with a purge sector.

It is possible to make variably adjustments to the position of the shaft in all directions to a perfectly balanced fit in the air handling unit.

Air leakage between wheel and casing is minimized with a brush sealant allowing easy adjustment, longer lifetime and low friction. Also the two airstreams are separated by adjustable brush sealants.

Typical airflows for Model EQ vary from 2 000 Nm3/h / 1 170 CFM to approx. 190 000 Nm3/h / 110 000 CFM.
