Treated Fresh Air Unit Manufacturers in Kolkata
Efficient TFA Units for Fresh Air Management
Treated Fresh Air Units are designed to circumvent, dehumidify, filter out, and deliver 100% outdoor air into industrial and commercial buildings. Treated Fresh Air Unit Manufacturers in Kolkata can offer committed outdoor air systems with total enthalpy heat recovery, multi-level filtration, and deep cooling coils. EUROCON TFA units are available with airflow from 1,000 to 50,000 CFM, static pressure up to 1,800 Pa, and cooling or thermal duty from 4.0 to 140 TR. The systems are designed to improve clean-air ventilation while improving strength from exhaust air.
TFA (Treated Fresh Air Unit) — 100% Fresh Air & Energy Recovery DOAS
Each TFA (Treated Fresh Air Unit) is manufactured at Eurocon's state-of-the-art facility using CNC laser cutting, automated lock-forming, and precision structural engineering to ensure minimal casing leakage and maximum lifecycle reliability.
What Is a Treated Fresh Air Unit?
A TFA unit is a dedicated outdoor air device that treats incoming ambient air before providing it to the occupied or processed place. It can perform filtration, cooling, dehumidification, and energy recovery depending on the selected configuration. A rotary total enthalpy wheel can recover up to 75% of sensible and latent exhaust energy.
For business and business ventilation projects, a Treated Fresh Air Unit Manufacturer in Kolkata can configure the unit with chilled-water or DX cooling coils, multi-level filters, EC plug fans, or V-belt centrifugal fans. The machine also can consist of hot-water coils or electric heater banks where heating is required.
Construction & Insulation
EUROCON TFA devices are constructed in single- or double-skin casing with 25 mm or 50 mm injected PUF insulation at a density of 40 kg/m³. Thermal-break aluminum profiles help lessen undesirable thermal transfer through the casing. Heavy-gauge anti-corrosive construction also can be particular for pressureful environments.
For projects requiring customized fresh-air system, Treated Fresh Air Unit Manufacturers, Kolkata can configure casing thickness, motor class, coil rows, filtration banks, and different parameters according to the MEP specification. Units are synthetic, using CNC laser cutting, automatic lock-forming, and precision structural engineering, observed through pre-dispatch inspection.

Energy Recovery, Fan & Filtration Options
The TFA range can use a rotary total enthalpy wheel, sensible heat wheel, or run-round coil loop for energy recovery. Filtration can consist of EU4 pre-filtration, EU7/EU9 fine filtration, chemical gas-phase carbon, and terminal HEPA options. The fan segment can use a direct-drive EC plug fan or V-belt centrifugal fan.
For unique construction and process requirements, Treated Fresh Air Unit Suppliers in Kolkata can offer motor capacities from 2.2 to 75 kW with IE3, IE4, IE5, or EC high-efficiency configurations. 6-row or 8-row copper-tube coils with hydrophilic fins are available for deep cooling applications.
