Schedule
 EQUIPMENT:
Equipment and systems covered by this certificate are as follows
 
 

The heaters type DHF.C, type DHG.C and type DHK.C serve for heating under normal operating conditions non explosive liquids or gases. The heaters may be used either in gas hazardous areas or in dust hazardous areas.

  

The heaters type DHF.C, type DHG.C and type DHK.C consist of a enclosure in the type of protection flameproof enclosures “d”, a terminal enclosure in the type of protection increased safety “e” and the heating elements, which are connected in the flameproof enclosure. In the flameproof enclosure temperature monitoring and control equipment are installed.

  

The temperature sensors can be conducted intrinsically safe. In this case the electrical connection is made in an Ex i terminal enclosure.

  

If the electrical connection is made directly in the flameproof enclosure, the terminal enclosure in the type of protection increased safety “e” is omitted.
