Treated Fresh Air Units

April 28, 2011

 

Content:  Fresh air handling units are used for supplying fresh air at a desired temperature inside the building. Treated Fresh Air Units are designed to serve as a solution for IEQ and Energy Saving in a single modular unit with option to add modules for cooling, heating, humidification, high efficiency filtration, mixing, sound attenuation, etc.

Treated Fresh Air Units (TFA) are also sometimes referred to in the industry as Fresh Air Handing Untis FAHU, Fresh Air Units, Rooftop Units, Outdoor Air Handing Units OAHU, Energy Recovery Units or simply Air Handling Units.

DRI Treated Fresh Air (TFA) Unit is designed to be not only energy efficient but to save energy and control humidity as well. It adds to your bottom line with the best life cycle cost (LCC) in the industry.

Why DRI TFA ?

  • Ensures great Building Indoor Air Quality (IAQ)
  • Reduced Aircon and thus, Energy Costs
  • Helps qualify for LEED Certification

 

How does the DRI Treated Freah Air Unit work ?

The heart of the FlexAir Treated Fresh Air Unit is the EcoFresh desiccant coated energy recovery wheel, which slowly rotates between its two sections. In one section, the stale, conditioned air is passed through the wheel, and exhausted in the atmosphere.

During this process, the wheel absorbs sensible and latent energy from the conditioned air, which is used to condition (cool / heat) the incoming fresh Air in the other section, during the second half of its rotation cycle. Thus, you can have more fresh Air at lower humidity levels and energy costs inside your conditioned space.

 

Ideal for :

  • Hospitality – Hotels, Restaurants, Pubs, Bars, Discotheques . . .
  • Healthcare – Hospitals, Nursing Homes, Operation Theatres, Nurseries, Burn Wards . . .
  • Commercial Areas – Supermarkets, Departmental Stores, Office Buildings, Conference Facility . . .
  • Educational and Recreational Areas – Schools, Auditoriums, Bowling alleys . . .

All other conditioned spaces . . .

 

Advantages :-

  • Time Tested Reliability
  • Casing Air Leakage
  • Maintenance-Free Reliable Operation
  • Very Low Pressure Drops
  • Easy to Maintain Fan Assembly
  • High Quality Standardized Filters
  • Uniquely Designed Connection System
  • Best Technology in Casing Manufacturing
  • New Modular Design – More Model Options
  • Molecular Sieve Coated Heat Wheels

 

Features :-

  • Almost no cross contamination.
  • Over 80% energy recovery, both latent and sensible. Ideal for tropical climates where latent loads are 2-3 times the sensible load.
  • Total energy recovery, recovers both latent and sensible energy.
  • Specially, adjustable purge section rules out cross contamination of air stream (less than 0.04%).
  • Special labyrinth sealing arrangement ensures no cross leakage of air stream between the supply and exhaust section.
  • Most advanced technology.
  • Certified/ Tested in international labs.
  • Wheels edges hardened to suit marine/ coastal application needs.
  • Best LCC (Life Cycle Cost).
