Maxivent WTW Air Handling Units with Counterflow Heat Exchanger 700 m³/h with Horizontal Left Hot Water Coil - PHE 700 H WOJL
The Maxivent WTW air handling units with counterflow heat exchanger 700 m³/h with horizontal left hot water coil - PHE 700 H 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 has a maximum airflow of 870 m³/h and a thermal efficiency of 82%. 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 and helps prevent frost formation in the heat exchanger. The air handling unit is designed for floor mounting and can be opened on the left side for maintenance.
Benefits and Features
- Hot Water Coil: Ensures efficient and even heating of the supply air by utilising 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 electrical consumption.
- Counterflow Heat Exchanger: The integrated, efficient counterflow heat exchanger recovers 82% of the thermal energy from the exhaust air without mixing the air streams.
- Panel Filter F7/M5: Provides a high level of filtration of dust particles and contaminants from the outside air, contributing to a healthy and comfortable indoor climate and protecting internal components.
- Automatic Summer Bypass: Enables summer and night cooling by allowing cool outside air to be supplied directly without warming in the heat exchanger.
- Plug-and-Play Control: The air handling unit is delivered complete with built-in control for all functions, ensuring quick and easy installation and commissioning without the need for additional controls.
Applications and Usage
The Maxivent WTW air handling units with counterflow heat exchanger 700 m³/h with horizontal left hot water coil - PHE 700 H WOJL are developed for small to medium-sized commercial spaces such as offices, meeting rooms, clinics, shops, 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 outdoor temperatures. The integrated control and summer bypass ensure a comfortable indoor climate throughout the year, both in winter and during warm periods.
