Look at the direction of airflow supplied to indoor, it’s left type if water pipes are located on the left side of the unit;
otherwise, it’s a right type. For standard AHU, service door, wiring port and water pipe locate on the same side.

● Up-down layer construction, concise, compact.
● Rotary heat exchanger(RHE) as a basic part. Humidifying section, coil section etc. selectable as per requirements.

Combination ：RHE + coarse/medium filter + mix air + cooling/heating coil + fans

1. Rotary heat exchanger is composed of heat rotor(wheel), frame, drive system, double purge sector and sealing
parts etc..
2. Supply air(SA) passes through half of the wheel, exhaust air(EA) passes through reversely the rest half of the
wheel, meanwhile the wheel is rotating driven be the drive system. Thus, the wheel can be self-cleaning.
3. Drain pan is equipped under the wheel, in case condensed water occurs from fresh air in summer or return air in
winter when their temperature is decreasing. Meanwhile, make sure the drainpipe is expedite and waterseal is
installed.
4. Ice jam might occur on the exhaust side when operating in very cold area, if so, rotary speed reduction or turn-on
of bypass is required to ensure safe operation of the wheel.
5. On some occasions with strict cleanness requirement, to minimize the carryover from return air to supply air,
exhaust fan shall be placed in the leaving section of the exhaust side to create passive pressure, and the pressure
shall be lower than that of supply side, so that the double purge sector can perform more effectively.
6. For easy transportation or easy installation in limit space, the wheel can be cut into segments.

We offer different types of fans such as direct driven centrifugal fan, belt driven DIDW forward centrifugal fan, and
belt driven DIDW backward centrifugal fan etc..
