Schedule
 EQUIPMENT:
Equipment and systems covered by this certificate are as follows
 
 
 
Description
 
The heater type EH* ********-T* is used for a direct or an indirect heating of gases, liquids and solid bodies in areas endangered by explosive atmospheres for zone 1 and 2 respectively zone 21 and 22.
 
The electrical heater is suitable for a mounting into boxes, machines, tubes or canal systems.
 
The heater may only be used with safety systems. For example temperature-, flow-, level-, current- or insulation-control.
 
The heater consists of the a terminal box that could be designed in the type of protection flameproof enclosure or increased safety for use in areas endangered by gas or in type of protection “protection by enclosure” for use in areas endangered by dusts. Optionally the terminal boxes can already be certified as separate equipment. In this case the electrical and thermal ratings have to be taken into account.
 
Optionally a connection enclosure in type of protection increased safety or protection by enclosure can be installed directly below the terminal box. The connection between the two enclosures occurs with separately certified cable bushings that are suitable for this purpose. Alternatively the connection enclosure can be installed with a distance to the terminal box. In this case the connection between the two enclosures occurs with separately certified cable glands that are suitable for this purpose.
 
The connection box can optionally be filled up with sand or a potting compound.


 SPECIFIC CONDITIONS OF USE:   YES as shown below:
 
 
 
The temperature class and surface temperature, a monitoring unit (level, flow rate) if applicable and further operating conditions (ambient temperature range, self heating, conduction of heat, mounting orientation, etc.) have to be fixed with the testing of the complete heating construction.
 
The used safety devices for limiting the temperature, monitoring the flow rate and/or monitoring the level have to be suitable for this purpose and have to be certified.
 
The heater with flow rate monitoring may only be used when the flow rate is above the minimum flow rate that was basis for the temperature measurement.
 
The heater with level monitoring may only be used when the level is above the minimum level that was basis for the temperature measurement.
 
In case of medium temperatures at the outgoing part that were higher than the temperature class of the heater, the thermal isolation has to be taken into account for the explosion protection measure.
In addition to the surface temperature of the box, other parts (e.g. flange, nameplate, valves and accessories, etc.) that can be heated impermissible have to be part of the isolation or the thermal conductance have to be suppressed.
The thermal isolation has to prevent the migration of gases and vapours of the surrounding environment to the hot parts.
The thermal isolation is not part of this type examination.
 
The positioning of the temperature sensors for the temperature limiter has to be carried out in such a way, that a failure of one phase is included.
 
The conditions of safe use of the separately certified equipment / components have to be taken into account.
