Application engineering note
A greenhouse fan layout should identify whether the equipment is circulating indoor air or exchanging air with the outside. Each task needs its own airflow path, fan positions and operating sequence.
Describe the intended air movement
For circulation, provide the crop layout, mounting height, obstructions and the direction of the intended air movement. For outside-air ventilation, include the inlet and outlet openings, screens, shutters and any connected ducts. State the required airflow and the resistance the fan must overcome.
LONGWELL’s LWAE family provides EC axial fan configurations. The selected assembly still needs its power supply, mounting arrangement and environmental requirements confirmed for the proposed location.
Coordinate control and installation
Identify the operating modes used by the greenhouse controller and the required fan speed-control interface. Include the expected temperature, humidity, condensation and cleaning exposure at the fan location.
Show fixing points, protection, wiring access and the route for servicing or replacing the fan. Agree how the installed airflow will be assessed across the intended growing area. Heating demand, humidity management and crop performance depend on the complete greenhouse design and operation, so the fan proposal should state the particular air-movement task it is intended to support.
