Air curtain HUMMER E
The HUMMER air curtain has been designed to reduce heat loss in winter and protect interiors against hot air inflow, dust and insects in summer. It is intended for industrial doors and gates in buildings such as warehouses, workshops and production halls. The unit is equipped with a two-stage PTC heater (400V).
About the product
The HUMMER air curtain with a PTC heater is designed for industrial doors and gates in warehouses, workshops and production halls. In winter, it reduces heat loss, while in summer it protects the interior against the inflow of hot air, dust and insects.
The three-phase PTC heater, powered by 400 V, operates in two power stages: 7/14 kW or 10,5/21 kW depending on the model. This allows the heating intensity to be matched to the outdoor temperature and the frequency of door openings. Airflow from 4 200 to 9 500 m³/h and a reach of up to 7 m make the unit particularly effective in loading zones and at intensively used doorways.
The powder-coated galvanised steel housing provides resistance to corrosion and mechanical damage, and the 3-stage AC induction motor has IP54 protection. The included mounting kit allows horizontal or vertical installation, and for wide gates several units can be connected into a single modular system. The electric power supply does not require a connection to the building’s heating system, which simplifies installation in facilities without access to hot water.
