Innovation. Design. Quality.
The door leaf and architrave are made of 304 or 316 stainless steel and incorporate the inflatable seal. The standard seal is silicone, but EPDM is available upon request.
Architrave and door leaf are supplied in a polished finish as standard to <0.6Ra, but finer finishes are available upon request.
Hinge sets are provided in cast stainless steel material and come with a satin finish.
The window is available:
- 6mm thick round toughened clear glass double-glazed vision panel
- 6mm thick square toughened clear glass double-glazed vision panel
- 6mm thick radius toughened clear glass vision panel
Additionally, a privacy cover is available and added to one side of the door leaf only.
Sub-Frame type:
Bolted Sub-Frame (Stud Partition, Block, or Modular Partition Wall) – A 5mm Zintec steel frame is to be fixed into the wall to form the engineered structural opening, available with a compression seal to the door frame.
Cast-In Door Frame (Concrete Wall) – The door frame is designed to be fully cast into the wall during the shuttering process. The frame is filled with concrete during casting, eliminating the need for site welding or grout filling. It includes stops for the performance coating.
Cast Sub-Frame (Concrete Wall) – A 5mm stainless steel grade 304 frame is to be cast into the concrete walls to form the structural opening. It is available with a compression seal or welded seal to the door frame. If welded, the frame will require grout filling on-site post-welding.
PBSC’s inflatable seal airtight door set is designed to provide a strong barrier against leakage resistance for pressure differences up to 2000Pa (8″ w.g.).
Compressed air inflates the seal and is securely fit to the curved doorframe. This feature enables the use of reliable software during the FAT, which reduces on-site time and risk.
The door is designed with PBSC’s unique cast stainless-steel hinge assembly and includes a strong tempered or laminated glass flush-glazed vision panel that fits seamlessly within the stainless-steel door frame.
The inflatable seal is created by joining a hollow extruded profile to form an airtight seal that can be inflated to seal two surfaces. Providing a clean, time-saving sealing solution to hermetic sealing against powders, gases, liquids, and dust.
Following on-site installation, PBSC offers a Planned Preventative Maintenance and Servicing Plan with an extensive after-sales support service, including planned preventative maintenance programs, servicing, and spare parts.
