Model Q2 - Rotating Heat Exchangers

Product Info

Model Q2

Segmented rotary heat exchanger in casing

Model Q2 is Heatex rotary heat exchanger Model V in a galvanized steel casing. One of the greatest advantages with Model Q2 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 Q2 vary from 1 250 Nm3/h / 770 CFM to approx. 240 000 Nm3/h / 150 000 CFM.

Model Q2 holds several certifications, for example Eurovent and AHRI.
