Maxivent WTW Air Handling Units with Counterflow Heat Exchanger 5000 m³/h Featuring Hot Water Coil and DX Cooling Horizontal Left - PHE 5000 H WDJL T 01
The Maxivent WTW air handling units with counterflow heat exchanger 5000 m³/h, equipped with a hot water coil and DX cooling horizontal left - PHE 5000 H WDJL T 01, are high-quality, robust, and advanced balanced ventilation units with heat recovery, specifically designed for offices, practices, and medium to large commercial buildings. The AHU delivers a maximum airflow of 7120 m³/h and a thermal efficiency of 82%. The unit operates with a counterflow heat exchanger and EC fans and includes a hot water coil for heating and a DX cooling coil for supply air cooling. Designed for floor mounting, the unit can be opened from the left side for maintenance.
Advantages 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.
- DX Cooling Coil: Directly cools the supply air via direct expansion, ensuring indoor comfort during warm periods without the need for an additional chilled water system.
- EC Fans: Direct-driven EC plug fans with high-efficiency electronic commutation offer an energy-saving and quiet solution with low power 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 high filtration efficiency of dust particles and pollutants from outdoor air, contributing to a healthy and comfortable indoor environment while protecting internal components.
- Automatic Summer Bypass: Enables summer and night cooling by supplying cool outside air directly without warming through the heat exchanger.
- Plug-and-Play Control: The air handling unit comes complete with built-in control for all functions, allowing for quick and easy installation and commissioning without additional control systems.
Applications and Use
The Maxivent WTW air handling units with counterflow heat exchanger 5000 m³/h, hot water coil, and DX cooling horizontal left - PHE 5000 H WDJL T 01 are 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, hot water coil, and DX cooling, the unit provides comprehensive and energy-efficient climate control even under extreme outdoor temperatures. The integrated control and summer bypass ensure a comfortable indoor climate year-round, both in winter and during warm periods.
