Maxivent WTW Air Handling Units with Counterflow Heat Exchanger 2500 m³/h with Left-Hand Hydronic Coil - PHE 2500 F WOJL
The Maxivent WTW air handling units with counterflow heat exchanger 2500 m³/h and left-hand hydronic coil - PHE 2500 F WOJL is a high-quality, robust, and advanced balanced ventilation unit with heat recovery, specifically designed for offices, clinics, and small to medium-sized commercial buildings. The air handling unit features a maximum airflow of 2975 m³/h and a thermal efficiency of 83%. The unit operates with a counterflow heat exchanger and EC fans and is equipped with a hydronic coil that heats the supply air to the desired temperature while helping to prevent frost formation in the heat exchanger. The air handling unit is designed for ceiling mounting and can be accessed from the bottom for maintenance.
Advantages and Features
- Hydronic Coil: Provides efficient and even heating of the supply air using hot water from a central heating system or heat pump, resulting in a comfortable indoor climate and energy-efficient heat transfer.
- EC Fans: Direct-driven EC plug fans with high-efficiency electronic commutation (EC) offer an energy-efficient and quiet solution with low power consumption.
- Counterflow Heat Exchanger: The integrated, efficient counterflow heat exchanger recovers 83% of the thermal energy from the exhaust air without mixing air streams.
- Panel Filter F7/M5: Ensures a high level of filtration for dust particles and contaminants from outside air, contributing to a healthy and comfortable indoor environment while protecting internal components.
- Automatic Summer Bypass: Enables summer and night cooling by supplying cool outside air directly without warming through the heat exchanger.
- Plug-and-Play Control: The air handling unit is delivered complete with built-in controls for all functions, allowing quick and easy installation and commissioning without additional control systems.
Applications and Usage
The Maxivent WTW air handling units with counterflow heat exchanger 2500 m³/h with left-hand hydronic coil - PHE 2500 F WOJL is designed for small to medium-sized commercial spaces such as offices, meeting rooms, clinics, retail, and educational or healthcare facilities. Thanks to the combination of heat recovery, EC fans, and the hydronic coil, the unit provides stable and energy-efficient ventilation, even at low outdoor temperatures. The integrated control and summer bypass ensure the indoor climate remains comfortable year-round, both during winter and warm periods.
