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.
Treated Fresh Air Units (TFA) are also sometimes referred to in the industry as Fresh Air Handing Units FAHU, Fresh Air Units, Rooftop Units, Outdoor Air Handing Units OAHU, Energy Recovery Units or simply Air Handling Units.
The DRI TFA . . . . FlexAir Series comes from plant having over 10 years’ experience in making two stream systems.
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.
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.
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.
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.
The DRI TFA is manufactured in accordance with the best technology in casing manufacturing.
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.
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.
