TREATED FRESH AIR UNITS (TFAs)

   






The DRI Treated Fresh Air Units provide a complete 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.


Advantages with new series DRI TFA

Time tested Reliability
The DRI TFA . . . . FlexAir Series comes from plant having over 10 years' experience in making two stream systems.

Casing Air Leakage
The casing air leakage is of prime importance in two tier systems i.e. systems with two streams with high latent difference between both. The FlexAir Series TFA from DRI is designed in accordance with European Standard for leakage Class B.

Maintenance-free Reliable Operation:
Assured problem free operations even under tough circumstances as a result of solid construction with tight sealing between supply and exhaust air ensures minimal leakage.

Very Low Pressure drops
All functions like coils, heat exchangers etc. are optimised to give lowest possible pressure drop in proportion to highest possible efficiency resulting in very low LCC.

Easy to Maintain Fan Assembly

  • Fan assembly slides out for servicing. Saves time and money !
  • Reliable solid transmission construction saves belts and bearing.

High Quality Standardised filters

  • Deep folded bag filters with big filter areas and good sealing.
  • The good tightness ensures clean air supply to the room is of high quality.

Uniquely Designed Connection system
The unique design makes it possible for the assembler to choose from two different ways of connection when he assembles the unit in the machine room.

Best Technology in Casing Manufacturing
The DRI TFA is manufactured in accordance with the best technology in casing manufacturing.

New Modular Design . . . More Model Options
The new design allows for several functions to be placed in the same casing. The FlexAir series has a wider range to cover the flow range better making it possible for you to easily select the right unit with the lowest LCC.

Molecular sieve coated Heat Wheels

  • 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 ensure 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).

The DRI Treated Fresh Air Units ensures good IEQ in Hotels, Auditoriums, Multiplexes and other large Air-conditioned spaces !

Also Ideal for Healthcare and Pharmaceutical industry !
The requirement of fresh and clean air is very high in Healthcare and Pharmaceutical installations. The expression 'Air handling unit in hygienic design' means that it must be possible in an easy and effective way to clean these units' exterior and interior parts. It should be designed in a way that prevents growing of bacteria. It is also very important to design the complete unit to make it possible to inspect and clean between the different section parts like coils and heat exchangers.

The DRI Treated Fresh Air Units . . . FlexAir series meets all the criteria as it is designed and manufactured using selection of materials to comply to Hygiene needs!
