We are one of the prime organizations engaged in manufacturing, supplying and exporting Rotary Heat Exchanger Wheels. These wheels are engineered at our unit with the aid of our skilled professionals using premium aluminum foil that is obtained from our trusted sources. Our offered product is available with us in honey comb shape with perfect dimensional accuracy. These Rotary Heat Exchanger Wheels are heat to heat exchanger, which provide recovery of heat and humidity for various applications such as modular Air-conditioning units and Air Handling units.
Heat Recovery Wheels (HRW)/ Rotary Heat Exchanger Wheels (HEW) (Cassettes)
Heat Exchanger Wheel (HEW) / Rotor is for heat and humidity recovery for Indoor Air Quality (IAQ), Air Handling units, modular Air-conditioning units and many Industrial and civil air-conditioning system by saving energy. The Rotor / Wheel matrix is made of Aluminum foil formed in honey comb shape.
Sensible Rotor/Condensation Rotor:
In this model, Aluminum foil is coated with corrosion resistance material. It is used for sensible / heat energy recovery application only.
Enthalpy Rotor / Sorption Rotor:
The Rotor matrix made of Aluminum foil coated with 3Ao / 4Ao molecular sieve. It will recovery Total Energy (Sensible and Latent). It is widely used models for most of air-conditioning
Devfresh Heat Exchanger Wheel (HEW)
High performance, high efficiency heat and humidity recovery.
Brush seal with low pressure drop.
Polished and hardened surface.
Build in purge section.
Standard size range from HEW-500 to HEW-5000 models with Rotor depth 200mm, 250mm & 270mm. Customised Non Standard models can be doen also on request.
Heat Exchanger Wheel
DevFresh Heat Exchanger Wheel -HEW is for heat and humidity recovery for Indoor Air Quality -IAQ, Air Handling Units, modular Air-Conditioning units civil air-conditioning system and much more industrial purposes. Our Heat exchanger wheels which are also called as Energy recovery wheel are made of Aluminium base and on the surface are coated with Hygroscopic.
About the Product
DevFresh Heat Exchanger Wheel-HEW is a benefit for facility operators with regards to getting fresh Air and saving recurring expenses. Our Heat Wheels in the air-conditioning system means more outdoor air at lower energy cost reduced chiller load
Energy Conservation Wheels, Energy Recovery Wheels, Enthalpy Wheels, Sensible Wheels, Hygroscopic Wheels, Condensation Wheels or Sorption Wheels.
Devatech as a Company wants to meet the Users requirement as exact and as precise as possible. Every National government regulation to preserve and proper utilisation of energy has resulted in increasing the use of energy recovery equipment.
We strictly go with engineerÃÆÃ¢Ã¢Ã¢â¬Å¡Ã¬Ã¢Ã¢â¬Å¾Ã¢s suggestions which is otherwise called as perfect technical utility and end user awareness as the Investment in energy recovery equipment significantly reduce the energy costs associated with conditioning ventilation air, and lowers the investment initial cost in lowering stream heating, cooling and humidification equipment.
Devatech`s Aluminium made hygroscopic coating of the storage combination pulls the additional advantage of recovering moisture. Summer operation is dehumidification of warm and humid supply air to reduce the energy consumption of the down stream cooling equipment. During Winter this feature recovers moisture from the exhaust air to reduce the humidification load.
Energy Recovery from Devatech provides sound economic payback.
Energy Conservation Wheels are easily integrated and retrofitted in new ventilation systems. It can be easily installed into existing systems also. Delivers fresh air throughout the year at all conditions and Helps to meet ventilation standard without raising energy cost. As it Pre-conditions incoming fresh air maintains humidity conditions at no additional cost.
The Authority for Standard
The HVAC industry has responded to this indoor air quality (IAQ) concerns through its professional organization The American Society of Heating and Refrigerating and Air Conditioning Engineers which is Popularly known as ASHRAE
ASHRAE have issued IAQ Standard 62, entitled "Ventilation for Acceptable Indoor Air Quality". This standard specifies and stress on the need for continuous outdoor air ventilation as well as the importance of maintaining indoor humidity levels.
How to Recover Heat?
The combination of heat and humidity recovery of rotary heat exchangers is a highly efficient energy-saving. This is not a formula but is a Technology.
In the most of installation, the wheel is mounted in air handling unit AHU. It is positioned Supply and exhaust air each pass through half of the wheel in counter flow directions. The rotor media is a rotating transfer media.
In air-conditioning area, the cold air from air-condition room will pass through the half section of rotating honey comb cooling the metallic media which is Aluminium or other metal foil. This continuous rotating cooled media, after coming in other half section of frame, will cool the hot air coming from outside in the air-conditioned area.
It temporarily takes up the heat from the warm air stream and releases it in the colder air stream.
DevFresh Heat Exchanger Wheel (HEW) exchanger recovers both sensible (temperature) and latent (moisture) energy, and does effective job on Recovering the Heat and Humidity.
