Maxivent WTW Air Handling Units with Counterflow Heat Exchanger 1300 m³/h with Horizontal Left Hot Water Coil - PHE 1300 H WOJL
The Maxivent WTW air handling units with counterflow heat exchanger 1300 m³/h with horizontal left hot water coil - PHE 1300 H WOJL is a high-quality, robust, and advanced balanced ventilation unit with heat recovery, specially designed for offices, medical practices, and small to medium-sized commercial buildings. The air handling unit has a maximum airflow of 1625 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 while helping to prevent frost formation in the heat exchanger. The AHU is designed for floor mounting and can be opened on the left side for maintenance.
Benefits and Features
- Hot Water Coil: Provides efficient and uniform 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) 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 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 heating through the heat exchanger.
- Plug-and-Play Control: The air handling unit is delivered complete with built-in control for all functions, allowing quick and easy installation and commissioning without additional control equipment.
Applications and Use
The Maxivent WTW air handling units with counterflow heat exchanger 1300 m³/h with horizontal left hot water coil - PHE 1300 H WOJL are designed for small to medium commercial spaces such as offices, meeting rooms, medical practices, retail outlets, and educational or healthcare environments. Thanks to the combination of heat recovery, EC fans, and 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.
