Low-leakage Steel Door | ST-R/Z15 | Air Regulator

Low-leakage Steel Door | ST-R/Z15 | Air Regulator

Rectangular single leaf or double leaf doors that are robust and ensure only minimal leakage even in case of large differential pressures

• Maximum width of 1100 mm, maximum height of 2115 mm
• Maximum pressure loading of 1000 Pa, in closing direction; reinforced construction for up to 2000 Pa
• Air leakage rate of approx. 0.6 l/s or 2 m³/h at 1000 Pa (for each door leaf)
• Double skin door leaf made of galvanised sheet steel and with mineral wool infill
• Door frame made of angle sections or U-channel sections
• Two double lever locking devices, can be operated from both sides
• APT rubber seal, temperature resistant up to 90 °C
• Available in standard sizes and many intermediate sizes

Optional equipment and accessories

• Sound insulating lining
• Reinforced construction
• Any combination of cylinder rim lock, mortice lock, pressure relief valve, inspection window and removable exterior locking levers
• Powder-coated for outdoor installation

Application

• Low-leakage steel doors of Type ST are used as separating elements for walk-in plant rooms, storage rooms, air handling units, filter chambers, or enclosures for machinery or electrical equipment.
• Robust construction with very low air leakage rate even in case of large differential pressures
• Powder-coated construction with increased corrosion resistance
• Maximum pressure on the opening side is 1000 Pa (2000 Pa for reinforced construction)

Special characteristics

• Variants with additional sound insulating lining (X construction variants) provide good sound absorption
• U-value: 1.02 W/(m²K) at 8 W/(m²K) for internal spaces (air not in motion) and 25 W/(m²K) for outside (air in motion)
• Optional door frame without fixing tabs (-21) but with flange holes

Nominal sizes

• ST (single leaf)
  • B: 500, 600, 800 and 940 mm (intermediate sizes 400 – 1100 mm in increments of 1 mm)
  • H: 1500, 1600, 1800 and 1940 mm (intermediate sizes 800 – 2115 mm in increments of 1 mm)
  • Any combination of B × H
• ST-D (double leaf)
  • B: 1080, 1280, 1680 and 1960 mm (intermediate sizes 1080 – 2280 mm in increments of 1 mm)
  • H: 1500, 1600, 1800 and 1940 mm (intermediate sizes 800 – 2115 mm in increments of 1 mm)
• Any combination of B × H

Parts and characteristics

• Door with perimeter seal
• Double lever locking devices
• Absorption material
• Hinges
• Door frame

Attachments

•  Angle section frame with welded fixing tabs
•  U-channel frame 115 × 40 × 4 mm
•  U-channel frame 240 × 40 × 4 mm with welded fixing tabs
•  Angle section frame without fixing tabs
• Locks, inspection window, pressure relief valve, front locking lever: for the improvement and extension of the range of applications

Construction features

• Double skin door leaf; skin thickness of 1 mm and 1.25 mm (opening side), respectively
• Stiffeners at the level of the double lever locking devices
• Additional central stiffener from H = 1800 mm
• Double lever locking devices can be operated from both sides
• Seal is temperature resistant up to 90 °C
• Maximum pressure loading of 1000 Pa, in closing direction

Materials and surfaces

• Door leaf and stiffeners made of galvanised sheet steel
• Reinforced construction (V): Screw-fixed stiffeners
• Absorption material is mineral wool
• Door frame made of galvanised steel
• Double lever locking devices made of aluminium diecast
• APT rubber seal
• Sound absorbing Bitumen K57 slabs
• P1: Powder-coated, RAL CLASSIC colour
• PS: Powder-coated, NCS or DB colour

Mineral wool

• To DIN 4102, fire rating class A2, non-combustible
• RAL quality mark RAL-GZ 388
• Biosoluble and hence hygienically safe according to the German TRGS 905 (Technical Rules for Hazardous Substances) and EU directive 97/69/EC
• Inert to fungal and bacterial growth

Maintenance

• Maintenance-free as construction and materials are not subject to wear
• Contamination should be removed as it may lead to corrosion and to increased closed door air leakage
