Dewei purged panel control solutions are engineered to the hazardous area concept of Ex p to IEC/EN60079-2. Full calculations are undertaken in-house. Where cooling systems are required, forced fan cooling systems are replaced by the use of
vortex coolers.
Dewei has a range of purge units capable of pressurizing enclosures with a volume up to 12.7m3 without any additional calculations required. Larger systems are possible with the use of numerous purge systems and further heat dissipation calculations. Enclosures are available in stainless steel 316 or painted mild steel to the client’s specified paint system. All enclosures are rated IP66.
