ASSA ABLOY RP150 High-speed door for oxygen reduction systems
Controlled solution
Oxygen reductions systems (ORS) are being increasingly used as active fire protection, as opposed to the more traditional, passive solutions such as sprinkler systems. To maintain integrity, ORS require an effective barrier to support active fire prevention. For such systems in automated warehouses and material handling facilities, the ASSA ABLOY RP150 is an ideal solution.
This compact, airtight high-speed door is specifically designed to meet ORS requirements. With fast speed and short cycle times to increase product flow and process productivity, it delivers on the performance, efficiency and reliability you expect from ASSA ABLOY
Key features at a glance:
- Rapid opening and closing with cycle times up to 4 per minute
- High reliability even after extensive use
- Safety limit switches rated Category 4 PL e (EN ISO 13849-1)
- Compliant with EN ISO 12100 for machine safety
- Excellent airtightness in accordance with EN 16750/17
- Side frame light curtain or dual photocells for improved safety
- Frames and covers available in galvanised or stainless steel
- Control system with frequency converter (DCC 50) for smooth operation
Purpose-built for oxygen reduction systems
The ASSA ABLOY RP150 high-speed door is designed specifically to support oxygen reduction systems (ORS), which lower fire risk by reducing oxygen levels and limiting the potential for ignition. This door ensures a highly airtight seal, minimising air exchange to maintain controlled atmospheres essential in ORS-protected environments. Suitable for vertical installation, the RP150 offers dimensions from 500 mm up to 2,200 mm in width and 500 mm to 2,800 mm in height, with a maximum door area of 6.2 m². Its robust construction and airtight design help safeguard machinery, products and facilities by reducing the chance of fire spread.
Safety, control, and installation features
Safety is integral to the RP150’s design. For door heights above 1,370 mm, an integrated light curtain within the side frames protects the entire doorway. For smaller doors, two pairs of photocells monitor key heights, stopping and reversing the door if an obstruction is detected. The door’s bottom profile includes a weighted steel bar to assist in sealing and reduce curtain deflection under pressure. The powerful DCC 50 control unit allows flexible programming and connects to machinery via potential-free relay outputs indicating door status and faults. The door’s frame and covers are galvanised steel, with options for stainless steel or painted finishes. Installation is straightforward, with optional support frames and hand-operated crank controls available for manual override.
Meeting the challenges of oxygen reduction systems (ORS)
ORS operate by lowering the oxygen content in the air to prevent a fire from igniting and spreading within an enclosed area. This means that unregulated air flow, humidity, pressure, and room temperature can all increase fire risk. In turn, this jeopardises safety of machinery, products and equipment.
Because this high-speed door is airtight, it forms an essential component that meets and exceeds the stringent requirements of ORS, completely sealing off oxygen-reduced areas, reducing air exchange to a minimum.
