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

The heaters type DH..A0... and DH..B0... serve for direct or indirect heating of non-flammable liquids or none-explosive gases under operating conditions. They are intended for installation in containers. 

The heaters consist of a flameproof enclosure and a termination compartment in type of protection "increased safety". The flameproof enclosures are made of  grey cast iron or they consist of a welded assembly made of steel or stainless steel. The terminal compartment in type of protection "increased safety" may optionally be omitted at the welded enclosures. In this case the flameproof enclosures serves as electric terminal compartment with direct cable entry at the same time.

The heater enclosure can be complemented with suitable and certified Ex e or Ex i terminal boxes, which are fixed to a holder (e. g. pipe or clamp ring) with the heater enclosure. The composition of the protection symbol is based on the types of protection of components actually used.
