Product USP’s
Compact, Eco-Smart & Built for High-Performance Ventilation
At the heart of the TFA unit is a sensible or enthalpy heat recovery wheel that captures up to 85% of energy from exhaust air. This significantly reduces the heating or cooling load on incoming fresh air, ensuring year-round energy savings and enhanced HVAC performance.
Multi-stage filtration with G4 and F7–F9 filters ensures particulate-free, high-quality air. Optional upgrades like HEPA or carbon filters make it suitable for sensitive environments like healthcare, laboratories, and food-processing zones, enhancing both air purity and regulatory compliance.
The heat recovery wheel is made from epoxy-coated or aluminum media to resist corrosion and moisture damage. Combined with a powder-coated or stainless-steel casing, the unit withstands harsh operating conditions, delivering long-lasting, reliable performance.
EC or plug fans with VFD compatibility ensure dynamic airflow control and reduced power consumption. Paired with IE3 or IE5 motors, this configuration guarantees high efficiency, low noise, and smooth operation across diverse load conditions.
CO₂ sensors, UV-C lamps, and differential pressure gauges come as optional accessories to promote cleaner air and real-time monitoring. These smart tools help enhance safety, reduce contamination risk, and offer valuable data for proactive maintenance and performance tuning.
With airflow capacities ranging from 1,000 to 60,000+ CFM, the TFA unit is scalable for use in small classrooms to large industrial zones. Modular design and customization options make it adaptable to varied architectural layouts and HVAC systems.
Key Highlights
“Optimized Fresh Air Delivery with Heat Recovery Precision”
The TFA Unit with Heat Recovery Wheel is a cutting-edge solution for facilities that demand both superior air quality and energy efficiency. With a high-performance rotary wheel that recovers 70–85% of energy from the exhaust stream, this unit sharply cuts down on the energy required to condition incoming fresh air. Whether operating in cold or hot climates, it ensures year-round climate control while keeping operational costs in check.
The system comes equipped with EC or centrifugal fans driven by IE3/IE5 motors, ensuring quiet, efficient operation. A robust filtration system (G4 to F9, with optional HEPA) removes airborne contaminants and supports IAQ compliance. The heat recovery wheel, made from aluminum or epoxy-coated media, is corrosion-resistant and designed to endure moisture and pollutants for years.
Constructed using modular panels with high-density insulation, the TFA unit excels in both thermal and acoustic performance. Built-in UV-C lamps and sensor kits can be integrated to meet enhanced hygiene standards. Its compatibility with standard BMS protocols ensures centralized monitoring and control. Certified by Eurovent, AHRI, ISO, and CE, this unit meets global standards in safety, efficiency, and reliability.
