rotary heat exchangeralso called an energy wheel, or energy recovery wheeland the benefits of incorporat-ing such a device in an air handling unit. PRINCIPLES OF ENERGY RECOVERY Energy recovery involves a transfer of energy between an exhaust airstream and a supply airstream. Figure 1 illustrates the heat transfer process of an energy recov-
Heatex rotary heat exchangers provide very high sensible and latent efficiencies. Models with casing are fitted with seals for excellent airtightness and can be equipped with purge sectors to minimize the cross-contamination of exhaust air into the supply air. Heat Recovery Wheels - Achieve greater efficiency - SerckRotary-type heat exchangers have a wheel-like construction. This is why they are also known as heat wheels or simply rotors. The rotor, which is constructed like a wheel, consists of an aluminum honeycomb structure within a supporting frame. It rotates nonstop at a slow speed (20RPM) between the stream of hot air and the stream of cold air.
Principle of working for BryXchange Air to Air Rotary Heat Exchanger BryXchange rotor is installed between the high temperature exhaust air and supply air stream. As the rotor slowly rotates, sensible heat of temperature exhaust air is carried over by the rotor to the low temperature supply air. REM Rotary Heat Wheel Unit Armcor Air SolutionsThe REM series is the ultimate in High Efficiency Heat Recovery utilizing a rotary heat exchanger to recover the energy from the exhaust air and transfer it to the incoming fresh air. With efficiencies up to 87%, this unit configuration suits external rooftop or plant room applications and includes energy saving EC Plug Fans, in-built bag filters and an option of enthalpy or sensible rotary heat wheels.
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%. Entering the cold air half Rotary wheel heat exchanger - Eri Corporation S.r.lRotary wheel heat exchanger - Eri Corporation S.r.l. Rotary heat exchanger is regenerative type of air to air heat exchanger with diameter from 250 mm up to 5000 mm. Made with aluminum to reach above 85% efficiency. Certification. Technical drawing.

is important to install efficient energy recovery. Rotary heat exchangers offer high efficiency in a compact design and often provide the best return on investment. We offer two types of rotary heat exchangers:One for heating only; which we call a sensible wheel because it transfers only sensible energy and the other is for both heating and cooling. rotary wheel heat exchanger, rotary wheel heat exchanger The wheel transfers the energy (cold or heat) contained in exhaust air to the fresh air supplied to indoor. Working Principle Rotary heat exchanger is composed of alveolate heat wheel, case, drive system and sealing parts. Purge Sector Because of the structure of rotary heat exchanger, the outdoor air and exhaust air will mix.
Made of aluminum foils, the wheels feature countless small channels through which the air flows and transfers it´s heat to this storage mass. Aluminum is ideal for this process because of its high thermal conductivity. The storage mass of a rotary heat
