Polarteknik designs and supplies interior door systems for high-speed and intercity trains and metros.
Automatic, fire barrier door systems for the rail sector
Polarteknik’s product range includes complete fire barrier walls, as well as automatic, single / double leaf-sliding, telescopic, and curved doors, which can be installed in passenger coaches to increase safety and comfort. Polarteknik is dedicated to passenger flow in railway rolling stock.
Doors are available in manual or automatic versions, and can feature electric or pneumatic drives or a mechanical self-closing function.
The company is experienced in designing and producing fire barrier doors and fire barrier partitions that comply with prevailing national and international rolling stock standards.
Polarteknik is happy to engage in new build and refurbishment projects directly or through partnership arrangements.
Compact, recyclable, adaptable train doors
Polarteknik’s doors are compact, recyclable, lightweight, and fit into varying spaces and environments. They feature a modular design that is easy to install and maintain. The products’ high-quality components are thoroughly tested, and designed to last for 40 years with minimal maintenance.
The safety-related modular components are the same found in previous Polarteknik door design. A powerful microprocessor controls the doors’ integrated safety functions. Because of the modular design philosophy we can easily adapt the design from project delivery to another and use the same core design that is well proven in use.
The design concept places key components under a wall-mounted aluminium profile, and guarantees smooth and silent operation for customer comfort.
With modern design and validation the products can be made highly recyclable. In certain projects we have reached recyclability rates exceeding 98% and typically it is over 95%.
Qualifications and testing
Polarteknik is firmly committed to its quality control system, which is under constant development.
Products undergo electrical, functional, dimensional, and visual tests to ensure compliance with standards and customer requirements.
Non-insulating fire doors are tested against 20min integrity and rated EW20, while insulating fire doors are available for up to 30min integrity with EI30 rating.
Over the years Polarteknik has produced automatic and manual doors with fire integrity in the following ratings: E15, E20, EW15, EW20, EI15, EI20, EI30, E15I15, E30I15 and EW30I15. The company has witnessed dozens of tests and has extensive experience in fire integrity and interface design.
Railway rolling stock related operations are certified by the international rail transport sector (IRIS), and the company is compliant with the latest ISO 9001 and ISO 14001 standards. Welding and Gluing certificates complete the high level of production competence.
Polarteknik uses state-of-the-art technology, and cooperates with universities and independent laboratories as part of its project development process.
