CSD Series Ex D Enclosures
The CSD series Ex d enclosures are normally used in the chemical and petrochemical plants, off-shore platforms, refineries and any other industry where hazardous atmospheres (gas and combustible dust) are potentially present.
The CSD range of explosion proof junction boxes has been designed to meet the main requirements of power distribution and other electrical functions inside the hazardous area of the plant.
The materials used to manufacture the CSD series Ex d enclosures have been studied to grant the maximum protection against the highly corrosive agents present in these industries:
- body and cover of copper-free (lower 0.1%) aluminium
- external epoxy powder painting RAL 7001 finishing
- gasket on cover of silicone;
- internal and external earth screws of stainless steel complete with antirotation washers;
- cover provided with antiloosening screws of stainless steel and as option, with holding string to facilitate installation and maintenance operations;
- window of instrument housing of thermo resistant glass;
- all operators installed are external push button units which have passed a mechanical endurance test of 15 million operation cycles (standard), 1 million (selector) and 300.000 (emergency);
- contact blocks base is equipped with one to four contacts (NO, NC, NO+NC);
- diffuser with special design to grant a high visibility degree in any situation;
- integrated labels of polycarbonate, or stainless steel with possibility to customize the marking as per client specifications.
The CSD series Ex d enclosures are normally used for the following main applications:
- control stations;
- emergency call units;
- instrument housings;
- switches and changeover switches..
The bodies are available with two (CSDC or CSDU) or three (CSDY) hubs threaded 3/4”NPT as standard
and 1/2” NPT or M20x1.5 or M25x1.5 as option. The fixing support has been designed for the typical
installation on columns.
