Maxivent WTW Air Handling Units with Counterflow Heat Exchanger 4200 m³/h with Horizontal Right Hot Water Coil - PHE 4200 H WOJR T 01
The Maxivent WTW air handling units with counterflow heat exchanger 4200 m³/h with horizontal right hot water coil - PHE 4200 H WOJR T 01 is a high-quality, robust, and advanced balanced ventilation unit with heat recovery, specifically designed for offices, medical practices, and medium to large commercial buildings. The air handling unit has a maximum airflow of 5430 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 right side for maintenance.
Advantages and Features
- Hot Water Coil: Provides 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 electronically commutated (EC) motors offer an energy-saving and quiet solution with low electricity consumption.
- Counterflow Heat Exchanger: The integrated, efficient counterflow heat exchanger recovers 82% of the thermal energy from the exhaust 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 climate and protecting internal components.
- Automatic Summer Bypass: Enables summer and night cooling by supplying cool outside air directly without warming in the heat exchanger.
- Plug-and-Play Control: The air handling unit is delivered complete with built-in controls for all functions, making installation and commissioning quick and straightforward without additional control technology.
Applications and Use
The Maxivent WTW air handling units with counterflow heat exchanger 4200 m³/h with horizontal right hot water coil - PHE 4200 H WOJR T 01 have been developed for medium to large 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 outdoor temperatures. The integrated control and summer bypass ensure the indoor climate remains comfortable all year round, both in winter and during warm spells.
