Any working environment where explosive gas, vapour or dust atmospheres may form must be equipped with explosion protected electrical, electronic and mechanical equipment, ie equipment that has an acceptable low risk of creating an ignition source.
Two recent projects undertaken by Radio and Control highlighted the importance of this type of equipment.
Electric pallet jack safe operation in hazardous zone.
Conversion and certification of an electric pallet jack to safely operate in hazardous area
The Client required two electrical pallet jacks to safely operate in a hazardous area where explosive gasses from Propane to Hydrogen could be present. AJM Radio and Controls converted the pallet jack so that it could be certified “Explosion Protected” Ex des IIC T4 Gc.
Flameproof conversion and certification of electro/hydraulic proportional valve bank.
Conversion and certification of electro/hydraulic proportional valve bank to safely operate in hazardous area – Flameproof
AJM Radio and Controls converted Hydac Nord Hydraulic RS220 bi-directional valve banks so that it could be certified Group I/IIC, maximum surface temperature T4 (135EC) in
terms of SANS 60079-; Part-0:2009 and Part-18:2009.
It can be used in Zone 1 hazardous locations in Coal Mines or on surface in a Methane to Acetylene or Hydrogen atmospheres
