Maxivent WTW Air Handling Units with Counterflow Heat Exchanger 3500 m3/h with Right-Hand Hot Water Coil - PHE 3500 F WOJR
The Maxivent WTW air handling units with counterflow heat exchanger 3500 m3/h with right-hand hot water coil - PHE 3500 F WOJR is a high-quality, robust, and advanced balanced ventilation system with heat recovery, specifically designed for offices, medical practices, and small to medium-sized commercial buildings. The air handling unit offers a maximum airflow of 4115 m³/h and a thermal efficiency of 84%. It operates with a counterflow heat exchanger and EC fans, and includes a hot water coil that heats the supply air to the desired temperature while helping to prevent frost formation in the heat exchanger. The unit is designed for ceiling installation and can be accessed from the bottom for maintenance.
Benefits and Features
- Hot water coil: Ensures 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 featuring high-efficiency electronic commutation (EC) provide an energy-saving and quiet solution with low electricity consumption.
- Counterflow heat exchanger: The integrated, efficient counterflow heat exchanger recovers 84% of the thermal energy from the exhaust air without mixing air streams.
- F7/M5 panel filter: 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 supplying cool outside air directly without preheating in the heat exchanger.
- Plug-and-play control: The air handling unit is delivered complete with built-in control for all functions, allowing for quick and easy installation and commissioning without additional control equipment.
Applications and Usage
The Maxivent WTW air handling units with counterflow heat exchanger 3500 m3/h with right-hand hot water coil - PHE 3500 F WOJR have been developed for small to medium-sized commercial spaces such as offices, meeting rooms, clinics, retail stores, and educational or healthcare environments. Thanks to the combination of heat recovery, EC fans, and the hot water coil, the unit delivers 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.
