Maxivent WTW Air Handling Units with Counterflow Heat Exchanger 700 m³/h with Left-Hand Hot Water Coil - PHE 700 F WOJL
The Maxivent WTW air handling units with counterflow heat exchanger 700 m³/h with left-hand hot water coil - PHE 700 F WOJL is a high-quality, robust, and advanced balanced ventilation unit featuring heat recovery, specifically designed for offices, medical practices, and small to medium-sized commercial buildings. The air handling unit delivers a maximum airflow of 870 m³/h and achieves a thermal efficiency of 82%. Equipped with a counterflow heat exchanger and EC fans, it includes a hot water coil that heats the supply air to the desired temperature and helps prevent frost formation in the heat exchanger. The unit is designed for ceiling mounting and can be accessed from below for maintenance.
Benefits and Features
- Hot Water Coil: Provides efficient and even heating of the supply air by 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-saving and quiet solution with low electrical consumption.
- Counterflow Heat Exchanger: The integrated, efficient counterflow heat exchanger recovers 82% of thermal energy from the extract air without mixing air streams.
- Panel Filter F7/M5: Ensures a high level of filtration of dust particles and contaminants from outside air, contributing to a healthy and comfortable indoor environment while protecting the 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 integrated control for all functions, allowing for quick and straightforward installation and commissioning without additional control systems.
Applications and Usage
The Maxivent WTW air handling units with counterflow heat exchanger 700 m³/h with left-hand hot water coil - PHE 700 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 hot water coil, the unit provides stable and energy-efficient ventilation even at low outside temperatures. The integrated control and summer bypass ensure that the indoor climate remains comfortable all year round, both in winter and during warm periods.
