Air curtains, distinguished by their unique aerodynamic design, offer a highly efficient solution for separating two temperature zones or two environments. This unique design not only provides effective separation but also contributes significantly to energy conservation, making it a cost-effective choice.

When faced with challenges of natural heat exchange through open doors, air curtains step in as a practical solution. These curtains effectively separate two areas or environments, halting the natural heat transport and thereby playing a crucial role in energy conservation.

In principle, an air curtain is a device equipped with a fan and a heat exchanger (water or electrical). It operates by pushing air to the floor in a smooth, laminar flow, creating a 90% air seal. This seal, akin to an invisible waterfall, effectively stops heat transfer, dust, and flying insects, thereby maintaining a controlled indoor environment.

Function

• Four product models equipped with integrated controls eliminate the need for additional controls on the walls and allow for a clean, streamlined design.​
• Adjustable blowing speeds and an inbuilt schedule function for efficient management.
• Includes programmatic freeze protection and a Master-Slave function for synchronized operation.
• ​Integrated control valves and actuators, along with energy measurement, air bubble detection, and pressure measurement of the heating network.​
• Featuring a counter for door openings, enhancing overall functionality.
• Supporting ECM engines and allows optimized operation for each building.
• Ready-to-implement graphic images simplify design processes.
• Functional changes to easily adapt to specific needs.

Structure

• Available in four different widths: 1000 mm, 1500 mm, 2000 mm, and 2500 mm.

Material

• The frame is painted with light grey RAL 7035 and the grill with graphite grey RAL 7024.
• ​The heating radiator system features 3/8" copper pipes with aluminium strips for enhanced heat dissipation and a G1" internal thread for secure connections. Designed to operate at a maximum pressure of 6 bar and a temperature of up to 100°C.
• The electrical connections include a 2 m power supply with safety grounding, a spark plug, and additional interfaces like an M12 connector, Ethernet, and USB.​
• The fan is equipped with centrifugal blades and ball bearings for efficient and reliable operation.
• The system includes a 2-way heating valve, a heat energy meter, a G4 filter, adjustable blow impulse, and supports Modbus TCP, BacNet TCP, Modbus RTU, BacNet MSTP, and an I/O interface for connectivity.

Integrated controller

• The automation system of the door curtain unit provides significant advantages by ensuring all components are pre-tested and the control system operates as intended.
• The pre-tested control system adapts quickly to changing conditions, optimizing performance and energy efficiency in real time.
• This advanced controller integrates seamlessly with building automation systems via Modbus or BACnet interfaces. Network topology options include TCP/IP or RS-485, ensuring flexible and robust communication.
• ​It contains various integrated sensors for measuring air temperature, water-side energy meter, water pressure and freeze protection. Apart from these, external sensors can be connected.
• The controller can be integrated into the BMS, allowing all control signals to be managed directly through the BMS, except for the freeze protection function, which cannot be bypassed.
