Available with us is the precisely made Energy Recovery Wheels. The Energy Recovery Wheels recovers total energy (sensible as well as latent), assists in meeting all the requirements of Indoor Air Quality (IAQ), humidity control and energy saving. DRI offers the Highest Recovery Enthalpy Wheels in the world (Aluminum substrate coated with a choice of desiccants). Incorporation of EcoFresh Heat Wheels into the air-conditioning system means more outdoor air at lower energy cost (reduced chiller load). Also Known As Energy Conservation WheelsEnergy Recovery WheelsEnthalpy WheelsSensible WheelsHygroscopic WheelsCondensation WheelsSorption Wheels How Does the EcoFresh Wheel Work? In a typical installation, the wheel is positioned in an Air Handling Unit so that it is divided into two half moon sections. Stale exhaust air is drawn through one half and outdoor air through the other in a counter flow pattern. At the same time, the wheel is rotated. 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. Latent heat is transferred as the desiccant coating on the metallic substrate adsorbs moisture from the air stream that has the higher humidity ratio and releases the moisture into the air stream that has the lower humidity ratio. Operating Principle Latent heat is transferred as the synthesized metallic substrate condenses moisture from the air stream that has the higher humidity ratio through adsorption by EcoSorb (with a simultaneous release of heat) and releases the moisture through evaporation (and heat pick-up) into the air stream that has the lower humidity ratio. Benefits of EcoFresh Energy Recovery Wheels Pre-conditions incoming fresh airEasily integrated/retrofitted into new/existing ventilation systemsDelivers fresh air throughout the year at conditions very near inside conditionsHelps to meet ventilation standard without raising energy costMaintains humidity conditions at no additional costAllows reduction in system capacity by 30 to 65% Why EcoFresh is your best buy? High Selectivity . . . Almost no cross contamination : EcoFresh Heat Wheels MS 270 use desiccant Molecular Sieve 3Å (EcoSorb 300) coated/used on aluminum substrate. This limits the cross contamination to absolute minimum and ensure exclusion of contaminants in the air streams, while transferring water vapor molecules.In-built 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. Structural Rigidity State-of-the-art winding technology and adhesives give EcoFresh rotors a high structural strengthEcoFresh is 270 mm deep, which also gives it a higher structural strength Highly Polished Surface Vertical run out less than 1 mm per 1000 mm resulting in extremely low leakage across the seals Innovative manufacturing design Segmented and non-segmented optionsSpoke structure also ensures easy removal of individual wheels sections for cleaning or repair/replacement (in case of segmented plus)Metallic construction, coupled with the robust spoke structure allows for projects to be specified for larger wheel diameters Industry’s Highest Recovery/Performance High Desiccant loading / coatingEqual sensible and latent recovery, thus, comparatively higher sensible and latent recoveryHigher performance, lower pressure drops : 78% nominal at 700 FPM (3.5 m/s) and 0.67" w.c. (170 Pa) pressure dropLaminar airflow due to thin aluminum substrate and uniform desiccant coatingSuperior airflow characteristics allow design for higher velocities and flow rates Non contact labyrinth seal No wear and tearEffective sealingLong lifeBrush seal as option also available Frost Protection Wheel rotation speed control helps to limit frost formation by keeping the exhaust air temperature above the dew point. Wide Range Total energy recovery (Enthalpy) as well as sensible wheelsCustomized Flute height and Rotor depth optionsCassette as well as Rotor optionsStandard and Customized options500 mm to 5000 mm (dia.)Easy retrofit options
