Treated Fresh Air Units (Tfas)

The Treated Fresh Air Units (TFAs) 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.

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.

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