Improved enclosure range
Deltron Enclosures’ corrosion and impact resistant series has been improved and named the Fortis Enclosure Range
T
he company says that the combination of a premium
alloy with outstanding corrosion resistance, an enhanced painting process and excellent impact protection, offers long lasting protection over the combined effects of water, impact and corrosive environments. Tom Downing, product
manager at Deltron Enclosures says: “The Fortis range offers the same form and fit as the market leading thick wall cast aluminium enclosures, but with extra durability and corrosion resistance due to the low copper content in the alloy. Galvanic effects between copper and aluminium increase the speed of corrosion, so a lower copper content leads to slower corrosion of the aluminium; this series contains less than 0.1 per cent copper content, whilst most on the market contain three to four per cent. “We expect the enclosures to enter the market through high specification designs where the IP68 seal and corrosion resistance

are vital; such as environments with high levels of electrolytes, including marine, agricultural or buried applications, or in areas where the enclosure is susceptible to knocks.” In addition to the improved
alloy, a salt spray test simulated prolonged periods in a corrosive environment and although the enclosures are certified for resistance up to 1,000 hours, the test actually went on a further 18 weeks before being stopped, and the box was still not corroded. Furthermore, all IP testing was carried out after impact testing to verify that the seal is maintained when the enclosure is treated roughly. The enclosures also boast
reusable seals which will withstand up to 200 compressions or uses; many on the market are single use and not environmentally friendly. Multiple sizes are also
available in grey, black or red.
