TFKC A4 Series Energy Recovery Ventilator | 800–1000 m³/h ERV with HEPA & Enthalpy Core
Product Introduction
- Engineered for cold climate buildings, this side-access ERV delivers 85% heat recovery efficiency with automatic freeze protection that activates before ice formation can damage the core or disrupt airflow. The DC motor adjusts fan speed in real time based on internal CO2, RH, and temperature sensor data, maintaining fresh air delivery precisely matched to occupancy demand -- no wasted energy, no cold drafts, no manual adjustment required.
- The DC motor consumes up to 40% less energy than conventional AC motor equivalents, while 85% heat recovery efficiency reduces the thermal load placed on heating systems throughout winter. CE certified and compliant with ErP energy efficiency directives, this ERV qualifies for green building credits and helps contractors meet increasingly strict cold-climate building energy codes without additional HVAC investment.
- The side-access panel design gives maintenance teams full access to filters, heat exchange core, and sensors without disconnecting ductwork -- critical for reducing service time and labor cost in occupied buildings. Compatible with standard duct connections and wall or ceiling mounting, the unit integrates directly into new construction or retrofit projects. Pre-wired sensor outputs support BMS connectivity for commercial building management.
- Three built-in sensors -- CO2, relative humidity, and temperature -- feed continuous data to the smart controller, which automatically adjusts ventilation rate and activates PM2.5 filtration when air quality thresholds are exceeded. Freeze protection engages autonomously when outdoor temperatures drop, protecting both the unit and building occupants without any manual input. The result is healthy indoor air maintained around the clock with zero user intervention.

Product Details
As we know, ERV can be used with various heat pump air conditioning systems. It plays an important role in energy recovery ventilation by recovering energy, ventilating and purifying the air entering the room, and providing people with a more comfortable indoor living experience.
Moreover, for engineering projects, we can customize large-screen display, multi-machine linkage control display and other programs.

• Efficient cross-flow heat exchanger
Using polymer membrane material, this heat exchanger is designed for high-performance energy recovery ventilation, with heat recovery efficiency of up to 85% and enthalpy efficiency of up to 76%. The effective air exchange rate exceeds 98%, ensuring excellent energy recovery ventilation performance. It is flame-retardant, features long-term antibacterial and mildew-resistant properties, is washable, and offers a service life of up to 3–10 years.
• High-efficiency Energy/Heat Recovery Ventilation Technology
In the hot season, the energy recovery ventilation system precools and dehumidifies the fresh air. In the cold season, it humidifies and preheats the incoming fresh air.
• Double Purification Protection
Primary filter + high-efficiency filter can filter 0.3 μm particles, and the filtration efficiency is as high as 99.9%.
• PTC electric thermal function（Optional ）：cold winter can also have warm fresh air
• The purification efficiency of PM2.5 particles is as high as 99.9%
