Reliable Everywhere: Global Purge and Pressurization Solutions

Meeting explosion protection requirements when operating in harsh environmental conditions on board an FPSO tanker is a challenge for electrical equipment. The processes on board such a vessel can be controlled and monitored with the help of the pressurized, fully automatic enclosures of the 6500 Series from Pepperl+Fuchs. The enclosures are certified by Pepperl+Fuchs according to ATEX and IECEx for Zone 1 and temperature class T4, allowing the solution to be equipped with remote I/O systems as well as conventional operating equipment. They are made entirely of SS316L stainless steel, making them suitable for harsh offshore conditions.

One of the problems with printers installed in explosion-hazardous areas for quality control purposes is how to retrieve the label or paper from the machine and into the operator’s hand without additional effort. In Zone 1/Division 1 applications, this can be very difficult and impractical when explosion-proof or flameproof types of protection are involved. The 6500 Series purge and pressurization system enables this concept. The pre-assembled and fully certified enclosure solutions feature a visible printer control panel with integrated control elements to operate the printer from the outside, a printer label slot to retrieve the label, and an inspection window to check the process or the label roll fill level. The concept can be applied to the most common printer models and is quickly available as a plug-and-play solution.

A provider of marine communication platforms wanted to suit their system for use in explosion-hazardous atmospheres by protecting electrical components inside a purged domed enclosure. Therefore, the purge and pressurization system not only has to meet marine requirements but also has to be able to cope with extended temperature ranges, and needs to be certified for hazardous gases and dusts. The Pepperl+Fuchs 6000 Series purge and pressurization system already met DNV marine certification and the marine standard for control room requirements. The control unit is capable of fully automatic operation without the need for an operator interface and has degree of protection (IP66).
