Heat Recovery Wheel Products > Heat Recovery Wheel

Operating on air to air principle of heat transfer, Heat Recovery Wheel provides a way of recovering air conditioning energy in hot and humid climates. Due to the utmost quality of our range, we are involved in the list of highly acclaimed Manufacturers, Exporters and Suppliers of Heat Recovery Wheels.

12 Reasons Why Ecofresh is Your Best Buy:

Hardened Edges: Wheel edges hardened to suit marine/coastal application needs.

Highly Polished Surface: Vertical run out less than 1mm per 1000mm resulting in extremely low leakage across the seals.

Selectivity: Molecular Sieve 3Å* (Ecosorb 300) coated/used on aluminum substrate. This is recommended where there is a need to limit the cross contamination to absolute minimum and ensure exclusion of contaminants in the air streams, while transferring water vapour molecules.

Structural Rigidity: State-of-the-art winding technology and adhesives give Ecofresh rotors a high structural strength.

High Diffusion Rates: Molecular Sieve 4Å (Ecosorb 400) coated/ used on aluminum substrate. This allows for higher diffusion rate and slightly improved latent recovery without substantially sacrificing cross contamination.

Innovative Manufacturing Design: Segmented and non-segmented options.

Inbuilt Purge Sector Eliminates Cross Contamination: Purge section provides strict separation of air flows, preventing carryover of bacteria, dust and pollutants from exhaust air to supply air. Purge section and labyrinth sealing system limit cross contamination to .04% of the exhaust air concentration by volume.

Fire Resistant: Neither combustible nor does it support combustion.

Non Contact Labrynth Seals: No wear and tear, effective sealing & long life.

Industry's Highest Recovery/ Performance: 78% nominal at 700 FPM (3.5 m/s) and 0.67" w.c. (170 Pa) pressure drop. Equal sensible and latent recovery.

Wide Range:

--Sensible as well as Enthalpy wheel
--Customised Flute height and Rotor depth options
--Cassette as well as Rotor options
--Standard and Customized options
--200 mm to 5000 mm (Dia.)

Retrofit: Easy retrofit options


Benefits of Ecofresh Heat Recovery Wheel:

Pre-conditions incoming fresh air.

Easily integrated/retrofitted into new/existing ventilation systems.

Delivers fresh air throughout the year at conditions very near inside conditions.

Helps to meet ventilation standard without raising energy cost.

Maintains humidity conditions at no additional cost.

Allows reduction in system capacity by 30 to 65%.


How does the Ecofresh Wheel Work?

In a typical installation, the wheel is positioned in a duct so that it is divided into two half moon sections.


Stale air is drawn through the other half in a counter flow pattern. At the same time, the wheel is rotated slowly. Sensible heat is transferred as the metallic substrate picks up and stores heat from the warmer air stream and gives it up to the cooler one.
