Rotary heat exchangers have a wheel-like construction. which is why they are also known as heat wheels or simply rotors. Made of aluminum foils, the wheels feature countless small channels through which the air flows and transfers it´s heat to this storage mass.
Heat recovery on cooling If outdoor air temperature exceeds the exhaust air tem-perature, the rotary heat exchanger can be runned at maximum speed and a cooling effect is achieved on the incoming air. Description The electronic speed controller is constructed specially for rotary heat exchangers. The equipment consists of an

When it comes to recovering thermal energy in air-conditioning systems, nothing beats a rotary heat exchanger. No other energy-recovery system can rival its performance with large air …
A regenerative heat exchanger, or more commonly a regenerator, is a type of heat exchanger where heat from the hot fluid is intermittently stored in a thermal storage medium before it is transferred to the cold fluid. To accomplish this the hot fluid is brought into contact with the heat storage medium, then the fluid is displaced with the cold fluid, which absorbs the heat.
The Functional Principle of Rotary Heat Exchangers The combination of heat and humidity recovery of rotary heat exchangers is a highly efficient energy-saving technology. It is equally successful when used for comfort climate range, industrial plants or marine applications. It is common to have energy recovery rates between 70-90%.
Klingenburg Energy Recovery, Rotors for Heating, Ventilation and Air Conditioning Systems (HVAC), Save energy in the office, factory, at home and at sea.
A rotary heat exchanger may be mounted at either the hub or the rim. In either case, the mounting system must be capable of thousands of hours of operation, unlubricated, and in a highly oxidizing environment at temperatures in excess of 250°C (482°F).
ROTARY HEAT EXCHANGER WORKING PRINCIPLE. Cooling down and warming up the foil arising by air that flows between these two layers and during rotating process of heat exchanger part, the rotary heat exchanger mass is heated or cooled by air. Heating or cooling process will take place when channels replacing and when the opposite side is entering.
When it comes to recovering thermal energy in air-conditioning systems, nothing beats a rotary heat exchanger. No other energy-recovery system can rival its performance with large air volumes in …
Rotary heat exchangers can include a ride-along compressor, at least a portion of which can be rotated along with the heat exchanger. By rotating at least a portion of the compressor along with the heat exchanger, a sealed fluid circuit containing a two-phase working fluid can be provided.

A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, or heat recovery 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. Other variants include enthalpy wheels and desiccant wheels.
The transfer of heat can be between steam and water, water and steam, refrigerant and water, refrigerant and air, water and water. Now let's take a look as to what are the different types of heat exchangers. Types of Heat Exchangers – Rotary Wheel. A rotary wheel type heat exchanger has a large surface cylinder which is attached to the shaft.
rating 10-500 rpm, for maximum usage of the heat exchanger rotor. To prevent involuntary heat recovery, holding torque can be activated in the motor to hold a rotor still. aSpecially designed for driving rotary heat exchangers aBased on the EC and PM motor technology, a technology more efficient than both asynchronous motor and stepper motor
Rotary screw compressors from the SM series (from 5.5 kW) upwards can be equipped with PTG systems. Depending on the size of the compressor system, the PTG heat exchanger is either integrated within the unit or is installed externally.
Rotary, crossflow, counterflow plate heat exchanger calculation implemented by Eri Corporation S.r.l. The software gives the possibility to make choice of heat exchanging according to your individual demands. With Eri Corporation this process become understandable and simple.
The cleaning control system enables the automatic, electronic cleaning of the contaminated thermal mass of a rotary heat exchanger. Standby indicates readiness for operation. A start signal from an external contact, the start button or an optional time switch activates the cleaning procedure.

Rotary heat exchangers can be used in most types of applications. The three principal areas are comfort ventilation (e.g. homes, offices, hotels and airports); industrial ventilation (e.g. automotive industry) and marine ventilation (cruise liners and coastal environments).
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
