Maxivent WTW Air Handling Units with Counterflow Heat Exchanger 1300 m³/h with Left-Hand Hot Water Coil - PHE 1300 F WOJL
The Maxivent WTW air handling units with counterflow heat exchanger 1300 m³/h with left-hand hot water coil - PHE 1300 F WOJL are high-quality, robust, and advanced balanced ventilation units with heat recovery, specifically designed for offices, medical practices, and small to medium-sized commercial buildings. The air handling unit has a maximum airflow of 1450 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 mounting and can be opened from below for maintenance.
Advantages 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 84% of the thermal energy from the exhaust air without mixing the air streams.
- Panel Filter F7/M5: Ensures a high level of filtration of dust particles and contaminants from the outdoor air, contributing to a healthy and comfortable indoor environment and protecting internal components.
- Automatic Summer Bypass: Enables summer and night cooling by supplying cool outdoor air directly without warming it 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 technology.
Applications and Usage
The Maxivent WTW air handling units with counterflow heat exchanger 1300 m³/h with left-hand hot water coil - PHE 1300 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 the hot water coil, the unit delivers 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.
