Maxivent WTW Air Handling Units with Counterflow Heat Exchanger 2500 m³/h with Electric Heater Right - PHE 2500 F EOJR
The Maxivent WTW air handling units with counterflow heat exchanger 2500 m³/h with electric heater right - PHE 2500 F EOJR is a high-quality, robust, and advanced balanced ventilation unit with heat recovery, specifically designed for offices, practices, and small to medium-sized commercial buildings. The air handling unit has 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 an electric heater that ensures a stable and constant supply air temperature while preventing frost formation in the heat exchanger. The air handling unit is designed for ceiling installation and can be opened from the underside for maintenance.
Advantages and Features
- Electric Heater: Integrated electric post-heating prevents cold drafts and ensures a comfortable and stable supply air temperature, without the need for a hot water connection.
- EC Fans: Direct-driven EC plug fans with high-efficiency electronic commutation (EC) provide an energy-efficient and quiet solution with low electricity 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 degree of filtration of dust particles and contaminants from outdoor air, contributing to a healthy and comfortable indoor climate and protecting internal components.
- Automatic Summer Bypass: Enables summer and night cooling by supplying cool outdoor 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 easy without additional control technology.
Applications and Use
The Maxivent WTW air handling units with counterflow heat exchanger 2500 m³/h with electric heater right - PHE 2500 F EOJR have been developed for small to medium-sized commercial spaces such as offices, meeting rooms, practices, shops, and education or healthcare environments. Thanks to the combination of heat recovery, EC fans, and electric heating, the unit provides stable and energy-efficient ventilation even at low outdoor temperatures. The integrated control and summer bypass ensure that the indoor climate remains comfortable throughout the year, both in winter and during warm periods.
