Maxivent WTW Air Handling Units with Counterflow Heat Exchanger 4200 m³/h with Hot Water Coil and DX Cooling Horizontal Right - PHE 4200 H WDJR T 01
The Maxivent WTW air handling units with counterflow heat exchanger 4200 m³/h with hot water coil and DX cooling horizontal right - PHE 4200 H WDJR T 01 is a high-quality, robust, and advanced balanced ventilation unit with heat recovery, specifically designed for offices, practices, and medium to large commercial buildings. The air handling unit has a maximum air volume of 5180 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 for heating and a DX cooling coil for cooling the supply air. The air handling unit is designed for floor mounting and can be opened on the right side for maintenance.
Advantages and Features
- Hot Water Coil: Provides efficient and even 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: Cools the supply air directly via direct expansion, ensuring a comfortable indoor environment during warm periods without the need for an additional chilled water system.
- EC Fans: Direct-driven EC plug fans with high-efficiency electronic commutation (EC) offer an energy-efficient 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: Provides a high level of filtration of dust particles and pollutants 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 warming it 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 straightforward without additional control technology.
Applications and Usage
The Maxivent WTW air handling units with counterflow heat exchanger 4200 m³/h with hot water coil and DX cooling horizontal right - PHE 4200 H WDJR T 01 is developed for medium to large 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, hot water coil, and DX cooling, the unit provides complete and energy-efficient climate control, even in extreme 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.
