Explosive area: Chromatotec® solutions
Since 2009 Chromatotec® produces MEDOR® in Exp cabinet for hazardous areas. First with CSA certification for Class 1 Div 2, group C&D for USA. Then we have extended this certification to CSA international worldwide excluding Europe. Now we are glad to offer our MEDOR®, chromaTCD and chromENERGY certified for ATEX zone 2 Ex II 3G Ex pz IIC T4 for worldwide use.
The Exp cabinet is protected by continuous flow with a z-purge system. This purging system is composed of a pressure regulator with a flow restrictor to control the inlet dilution. A flow controller is located at the valve outlet to validate the flow out of the cabinet. The cabinet is pressurized and diluted continuously. The worst case is taken into account to calculate the dilution flow to stay under the explosive condition. If pressure inside the cabinet is not higher than ambient pressure the power is switched off by the Z-purge system. For service there is a by-pass key to open the cabinet without pressure inside.
For complete natural gas or process analysis, Chromatotec® proposes MEDOR® for sulfur analysis, chromaTCD for impurities in pure gas and chromENERGY for C1C6+ and calorific value. Due to its new improvements, Chromatotec® provides a full analytical solution for natural gas monitoring in hazardous area.
