installed , the surrounding gap must be sealed to uphold the level of ingress protection .
High durability enclosures
Spelsberg provides all CNC work on-site at its Midlands facility , and although Grifen supplies its own drawings , Spelsberg ’ s technicians can also create CAD designs . Providing a test prototype in days , Spelsberg then despatched the full quantity of Grifen ’ s order in less than three weeks . As a result of the enclosure ’ s precision CNC machining , combined with specially designed cable glands , when Grifen installed the control unit , this upheld the high IP rating .
“ Spelsberg ’ s machining ensures repeatability ,” says Gary . “ It ’ s also a fast turnaround , so it ’ s become a key service for us .”
Although Grifen ’ s control unit is designed to be accessed remotely , or via the digital display , the device is still required to present a variety of user and safety information . Spelsberg provides Grifen with digital printing directly onto the enclosure , providing a highly durable , long-lasting finish . Combined with Grifen ’ s graphic design , Spelsberg ’ s printing service also ensures a professional presentation .
Sprinklers are an essential component of a building ’ s fire protection system .
Time-saving service
“ Previously , we used stick-on labels . Printing directly onto the box is much more hardwearing , and it saves us significant time resource compared to manual application . It also ensures a high-quality finish ,” says Gary . controls from any impact . Grifen uses Spelsberg ’ s high-durability industrial enclosures , manufactured from polycarbonate . These boxes protect in temperatures up to 80 ° C , sufficient to match the rating of the electronics , and they endure until the sprinklers activate to quell the heat . The enclosures can also withstand water jets and provide a high IK09 impact resistance rating .
To accommodate the automated system ’ s multiple cable connections , as well as the control unit ’ s digital display , every enclosure requires a CNC machining process .
The digital display window , as well as the cable entry points , must be cut in specified locations and to exacting dimensions . Crucially , when the display and the cables are
While the capability of Grifen ’ s systems lay within its software functions , supported by the quality of flow control hardware , the protection of the automated system is fundamental .
“ We ’ re committed to Spelsberg for our enclosures ,” says Gary . “ We ’ ve put our faith in this process , and the quality of the service means there ’ s no going back .”
