Maxivent WTW Air Handling Units with Counterflow Heat Exchanger 3500 m³/h with Left-Hand Hot Water Coil - PHE 3500 F WOJL
The Maxivent WTW air handling units with counterflow heat exchanger 3500 m³/h with left-hand hot water coil - PHE 3500 F WOJL are high-quality, robust, and advanced balanced ventilation units with heat recovery, specifically designed for offices, medical practices, and small to medium-sized commercial buildings. The air handling unit has a maximum airflow capacity of 4115 m³/h and a thermal efficiency of 84%. The unit operates with a counterflow heat exchanger and EC fans and is equipped with a hot water 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 opened from below for maintenance.
Benefits and Features
- Hot Water Coil: Ensures efficient and uniform 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) provide an energy-saving and quiet solution with low power consumption.
- Counterflow Heat Exchanger: The integrated, efficient counterflow heat exchanger recovers 84% of the thermal energy from the exhaust air without mixing air streams.
- Panel Filter F7/M5: Provides a high level of filtration for dust particles and contaminants from outdoor air, contributing to a healthy and comfortable indoor environment and 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 comes complete with built-in control for all functions, allowing quick and easy installation and commissioning without additional control technology.
Applications and Usage
The Maxivent WTW air handling units with counterflow heat exchanger 3500 m³/h with left-hand hot water coil - PHE 3500 F WOJL are developed for small to medium-sized commercial spaces such as offices, meeting rooms, medical practices, retail stores, and educational or healthcare environments. Thanks to the combination of heat recovery, EC fans, and the hot water coil, the unit provides stable and energy-efficient ventilation, even at low outside temperatures. The integrated control and summer bypass ensure the indoor climate remains comfortable throughout the year, both in winter and during warmer periods.
