Treated Fresh Air Unit Manufacturers in India
100% Outdoor fresh air treatment units featuring total enthalpy heat recovery wheels, multi-tier filtration, and deep cooling coils.
EUROCON Treated Fresh Air (TFA) Units are purpose-built to condition, dehumidify, and filter 100% outside ambient air for modern indoor air quality (IAQ) and fresh air ventilation performance. Designed with double-skin 25mm / 50mm injected PUF insulation and thermal-break aluminum extrusions, Eurocon TFAs incorporate rotary enthalpy heat recovery wheels (recovering up to 75% sensible and latent exhaust energy), multi-stage filtration tracks (EU4 Pre, EU7 Microvee, and optional H14 HEPA), and high-efficiency deep cooling coils for maximum efficiency and fresh air purity.

PRIMARY INDUSTRIAL & COMMERCIAL ENVIRONMENTS
Treated Fresh Air Unit Manufacturers in India – Eurocon Systems LLP
Eurocon Systems LLP is one of the specialised treated fresh air unit manufacturers in India, building TFA units that condition, dehumidify and filter 100% outdoor air for offices, hospitals, hotels, pharmaceutical plants and educational buildings. Each treated fresh air unit is designed and manufactured at our facility in Rohad, Bahadurgarh (Haryana), and sized to the ventilation and humidity load of the building it serves.
Modern buildings need a steady supply of clean fresh air to keep carbon dioxide, odours and airborne contaminants under control. Outdoor air in most Indian cities is hot, humid and dusty, so it cannot simply be blown indoors. A treated fresh air unit cools, dehumidifies and filters this air before it reaches the occupied space or the main air handling units, protecting both indoor air quality and the energy performance of the HVAC system.
Why Choose Eurocon as Your Treated Fresh Air Unit Manufacturer
As a treated fresh air unit manufacturer, Eurocon focuses on energy recovery and dehumidification. Our TFA units can integrate a rotary total enthalpy heat recovery wheel that transfers heat and moisture between exhaust and incoming air, reducing the cooling load on the chiller or DX plant. Deep 6-row or 8-row chilled water or DX coils then remove the remaining moisture for intensive dehumidification.
Casings use a thermal-break extruded aluminium profile with 25 mm or 50 mm injected PUF insulation at 40 kg/m³ density, preventing condensation and heat gain. Multi-stage filter tracks accept EU4 pre-filters, EU7/EU9 fine filters and optional carbon or HEPA stages for VOC and fine particle control. Direct-drive backward curved plug fans with variable speed EC motors keep running costs low, and acoustically lined casings hold sound levels below 54 dBA.
The standard range covers 1,000 to 50,000 CFM, external static pressure up to 1,800 Pa and cooling capacities from 4 TR to 140 TR.
Treated Fresh Air Unit Applications
Eurocon TFA units are used in commercial office complexes and IT parks to meet fresh air ventilation standards, in hospitals, surgical theatres and isolation wards, in pharmaceutical formulation areas and cleanrooms, in hotels, banquet halls and convention centres, and in educational campuses and auditoriums with high occupancy.
In each case the TFA unit handles the difficult job of treating humid outdoor air, allowing the main air handling units or fan coil units to work more efficiently on the internal load.
How Eurocon Manufactures Every Treated Fresh Air Unit
Quality is built into every stage of production at our Bahadurgarh facility. Incoming sheet steel, aluminium and stainless alloys are inspected before cutting, and components are cut on fibre laser tables and formed on CNC press brakes for accurate, interchangeable parts. Fan impellers are dynamically balanced on calibrated machines for quiet rotation and long bearing life, and finished fans are tested to measure airflow against static pressure, power draw and sound levels.
Custom TFA Units, Delivered Across India
Every treated fresh air unit is configured to order, with choices of energy recovery, coil depth, filtration stages, fan type and controls. Performance data is shared with the quotation so consultants can review the selection before manufacturing begins.
From our plant in Haryana we supply treated fresh air units across India, including Delhi, Mumbai, Bengaluru, Chennai, Hyderabad, Kolkata, Ahmedabad, Kerala, Assam and Jammu & Kashmir. If you are evaluating treated fresh air unit manufacturers in India, share your fresh air quantity and design conditions with Eurocon Systems LLP and our engineers will recommend the right TFA unit.
