90% efficiency  of Holtop rotary heat exchanger

Rotary heat exchanger, also known as heat recovery wheel, thermal wheel and enthalpy wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of an air handling system, or in the exhaust gases of an industrial process, in order to recover the heat energy.

Specifications and dimensions of Holtop rotary heat exchanger

Working principle of Holtop rotary heat exchanger

Rotary heat exchanger is composed of alveolate heat wheel, case, drive system and sealing parts. The exhaust and outdoor air pass through half of the wheel separately, when the wheel rotates, the heat and moisture are exchanged between the exhaust and outdoor air. The energy recovery efficiency is up to 70% to 90%.

Product details  of Holtop rotary heat exchanger

Wheel materials

The sensible heat recovery wheel is made by aluminum foils of 0.05mm thickness. And the enthalpy recovery wheel is made by aluminum foils coated with 3A molecular sieve of 0.04mm.

Casing construction

Wheel Construction

The wheel of the rotary heat exchanger is made of alternating layers of flat and corrugated aluminum foil to form the alveolate

shape. Various height of corrugation is available. Flat surface ensures minimum leakage. Interior spokes are used to mechanically bond the rotor’s laminations. These are threaded at the hub and welded at the periphery.

Bearing and drive system

The hub of the wheel is equipped with life-time- lubricated ball bearing or roller bearing, and with covers at both sides. No maintenance is required under normal usage.

– V-belt with big interface. Long service life.

– Spring shock absorber insures steady operation.

– Integrated motor and speed reducer free from maintenance.

Installation types and motor position

The motor is installed at the corner of the rotary heat exchanger, the position of the corner is marked from no. 1 to 4, and the motor position is optional.
