While a plate unit can come close to matching the sensible energy recovery performance of a rotary heat exchanger, nothing can come close to the latent performance of an enthalpy rotor. In applications where humidity control (summer or winter) is important, the energy savings of an enthalpy rotary recovery device is the best.

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 …

A mechanical ventilation system with an air-to-air heat exchanger unit provides the air supply to the first floor. This unit is a rotary energy recovery system, which recovers both heat (sensible energy) and humidity (latent energy). Fig.2. illustrates the heat exchanger system installed on the first floor.

A heat-exchanger of the kind having a rotary disc-type matrix that comprises a foraminous core of ceramic material arranged to effect heat transference between segregated streams of gaseous heat-exchanging fluids; has an annular gap between the periphery of the ceramic disc of the rotary matrix and a surrounding coaxial metallic drive-ring; the annular gap containing radially-disposed ...

systems, the rotary heat exchangers ensure the best efficiency, ranging from 60% to 90%, depending upon operating conditions. This because of their very large exchange surface in proportion to their volume. The installed power of a plant is considerably reduced with the high efficiency of the rotary heat exchangers and with the possibility of ...

PTG plate-type heat exchanger system Rotary screw compressors from the SM series (from 5.5 kW) and upwards can be equipped with PTG systems. De-pending on the size of the system, the PTG heat exchang-er can either be integrated into the compressor or installed externally. Possible areas of application: Supplying heat for
