Greenhouse Farming AHU

Air Handling Unit (AHU) for greenhouse farming is far more than a standard ventilation fan. It is a precision climate system designed to manage temperature, humidity, CO2 levels, and air circulation simultaneously to optimize plant growth and energy efficiency.

Unlike standard HVAC units, greenhouse AHUs are engineered to handle high humidity, resist corrosion from fertilizers, and distribute air evenly across wide growing areas without damaging crops.

Heating & Cooling Coils (Hydronic): Most systems use hot/cold water from central boilers or chillers passed through coils to condition the air blown into the greenhouse.

Variable Airflow Fans: High-efficiency axial or radial fans allow for stepless speed control, adjusting airflow volume to match real-time climate needs while saving energy.

Filtration Modules: Advanced units filter incoming air to remove insects, pollen, mold spores, and bacteria, ensuring a clean growing environment.

Heat Recovery (Enthalpy): Many modern AHUs use heat exchangers to transfer heat and moisture between outgoing stale air and incoming fresh air, reducing energy loss by up to 83%.

Dehumidification: By mixing and circulating air, AHUs prevent condensation on leaves and fruits, reducing the risk of Botrytis and other fungal diseases.

Semi-Closed Greenhouses: AHUs are the key component in "Next Generation Growing," allowing growers to slightly pressurize the greenhouse with conditioned air, keeping pests out and maintaining a stable CO2 level without opening vents.

Energy Savings: By recovering heat from lighting or the building structure, AHUs can significantly reduce heating bills. One study showed an 8-23% energy saving compared to standard ventilation methods.
