Ecofresh MS Series Wheels 270 & SG 200 mm deep are ARI certified in accordance with ARI Standard 1060-2005 (Rating Air-to-Air Energy Recovery Equipment).

HOW DOES THE ENTHALPY ROTOR WORK

• Preconditions the incoming fresh air thereby saving energy as well as operational costs.
• Delivers fresh air throughout the year at very near inside conditions.
• Helps to meet ventilation standards with no considerable increase in energy bills.
• Maintains humidity condition at no extra cost.
• Allows reduction in air conditioning tonnage by 30-65%.
• Retrofits/integrates into existing/ new ventilation systems.

ECOFRESH ARI CERTIFIED ENTHALPY ROTORS:

The EcoFresh new generation high performance, ARI certified enthalpy rotors/cassettes are best for high total recovery/efficiency. In a typical installation, the wheel is positioned in a duct so that it is divided into two half moon sections. Stale air from the conditioned space is exhausted through one half while outdoor air is drawn through the other half in a counter flow pattern. At the same time, the wheel is rotated slowly (approx, 20 ~ 25 rpm) between the two airstreams.

Sensible heat is transferred as the metallic substrate rotates, picking up the sensible load from one air stream and releasing it to the other. Similarly the latent heat is transferred as the desiccant picks up moisture from the moist air stream and releases to the drier air steam.

OPERATING PRINCIPLE

Over A Dozen + Reasons . . .

Ecofresh energy recovery rotors and cassettes are engineered to provide for all season ventilation, providing acceptable IAQ year-round, normally without the expense of additional HVAC- direct expansion capacity and with minimal extra energy costs.

Advantage Ecofresh

1. ARI CERTIFIED
   Ecofresh Heat wheels MS Series, 270 & SG 200 mm deep are ARI certified. The ARI Certification confirm the high quality and performance standards to which DRI is committed.
2. HIGH PERFORMANCE
   The Ecofresh SG series energy recovery rotors/cassettes are coated with Ecosorb 100 special grade desiccant on aluminum foil substrate for assured high performance. They are ideal where there is a need for high total (Latent & Sensible) recovery.
3. STRUCTURAL RIGIDITY
   State-of-the-art winding technology and adhesives give EcoFresh rotors a high structural strength.
4. HIGHLY POLISHED SURFACE
   Vertical run out less than 1 mm per 1000 mm resulting in extremely low leakage across the seals.
5. HARDENED EDGES
   Wheel edges hardened to suit marine/ coastal application needs.
6. FIRE RESISTANT
   Niether combustible nor supports combustion.
7. INDUSTRY'S HIGHEST RECOVERY PERFORMANCE
   76% nominal at 600 FPM (3.0 m/s) and 0.76" w.c. (193 Pa) pressure drop. Nearly equal sensible and limits recovery.
8. BUILT-IN PURGE LIMITS 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.

   
   
9. NON CONTACT LABRYNTH BRUSH SEAL
   
   

   • No wear and tear • Effective sealing • Long life • Brush seal as option also available.

10. INNOVATIVE MANUFACTURING DESIGN
    • Segmented and non-segmented options.
11. RETROFIT
    • Easy retrofit options.
12. FROST PROTECTION
    • Wheel rotation speed control helps to limit frost formation by keeping the exhaust air temperature above the dew point.
13. WIDE RANGE
    • Sensible as well as Enthalpy wheels
    • Customized Flute height and Rotor depth options
    • Cassette as well as Rotor options
    • Standard and Customized options
    • 19" (485 mm) to 196.9" (5000 mm).
