Stertil Stokvis has recently boosted its acclaimed range of doors with the launch of a model designed to offer greater fire resistance plus another for cleanroom applications that protects against airborne contamination.

The company’s new PIR door, which features a very special foam core developed by construction industry specialist Kingspan, represents a step change in modern door manufacture. This door is constructed from steel sandwich panels with a polyisocyanurate (PIR) core. The polymer structure of PIR is superior to the industry standard polyurethane (PUR), in that it is difficult to ignite and self-extinguishing, thereby providing enhanced fire resistance. PIR already has an excellent track record in real fire situations in many different types of buildings including schools, hospitals, warehouses and factories.

As well as the improved fire resistance, PIR panels also offer enhanced long-term characteristics, such as low heat conductivity, excellent mechanical parameters and low water absorption. Their very fine cell structure and high closed cell content gives the panels a superior ? coefficient, especially when compared to PUR foamed panels.

As with all products in its range, Stertil Stokvis’s attention to detail is apparent, with high quality materials and precise process control in manufacture adding up to an expectation of long and reliable service. Furthermore, the new door panels are HFC, CFC and HCFC free, with the insulation core having been awarded a Low Global Warming Potential classification. The excellent thermal properties of the door will also help keep energy costs down.

“We’re very pleased to be adding to our range of doors with this new model,” comments Andrew Georgiou of Stertil Stokvis. “This is a value-added and future-proofed product offering many benefits, which I know will be very appealing to specifiers, developers and building owners. Users of the new door will be able to look forward to top performance, exceptional reliability and unparalleled health and safety features.”

Stertil Stokvis’s second new door – the RapidRoll Clean – has been developed to meet the requirements of all cleanroom applications across numerous industries and environments including medical, pharmaceutical, biotechnology, electronics, aerospace, nanotechnology, optics, food and cosmetics. Meeting international standards for cleanroom applications up to ISO Class 5 (EN 14644-1) or GMP Class C with pressure differences up to 50 Pa, the cleanroom suitability of the doors has been certified by the Fraunhofer Institute in Munich. Super-fast operating speeds minimise air exchange between different areas when open and help to maintain air pressure differentials when closed. All doors and associated materials, including PVC curtains and stainless steel frames and rails, are designed for easy cleaning to help promote the highest standards of hygiene and cleanliness.

Stertil Stokvis RapidRoll Clean Doors are available in standard sizes ranging from 1000mm wide x 1000mm high to 3500mm wide x 3500mm high. Impressive opening and closing speeds of 2.0metres/sec and 1.0metre/sec respectively ensure fast, safe and unobstructed movement of personnel and goods between areas.

Operating safety has been paramount in the design of the new RapidRoll Clean range of fast-action doors. The standard self-testing contact safety edge stops the door closing and returns it to fully open in the event of striking an obstruction. Alternatively, for additional safety and protection, an STS Stertil Stokvis touchless (non-contact) safety system incorporating a pre-running photocell can be specified. A door line photocell also prevents closing if the door is obstructed.

The new doors are supported by a wide range of activation systems and can be supplied with controls and interlocks for air lock systems which help to maintain air cleanliness levels in different zones of a facility. The innovative MCCVectorControl is supplied as standard. This programmable-frequency converter system is extremely compact, featuring easy plug-in connections, and ensures smooth door operation. The control panel features foil keys and a graphical display for easy operation and maintenance. The control unit and main switch are conveniently located in the side column whilst a contactless actuator may be specified for greater hygiene.

Commenting on the new RapidRoll Clean range, Andy Georgiou says, “This launch heralds the most significant development since we introduced the original RapidRoll door to the market over 40 years ago. Enhancing the proven benefits of fast action, reliable performance and excellent after-sales support, our RapidRoll Clean range offers the highest standards of hygiene and cleanliness.”
