Schedule
 
EQUIPMENT:
Equipment and systems covered by this certificate are as follows:
 
The TWIH Range of Flameproof immersion heaters are constructed from 316 stainless steel and consist of a single cylindrical main housing with a bolt on cover. The main housing is 300 mm long for all models, with each model varying in diameter and wall thickness. The main housing consists of a cylindrical pipe section with welded base plate and slip on flange. The cover is fastened to the rim of the slip on flange via M6 high tensile socket head cap screws. Sealing of the lid is achieved via an O-ring fitted in an O-ring groove in the housing rim. Cable entry to the enclosure is via threaded couplings welded to the side wall of the main housing. The number and size of threaded entries in the main housing can vary to suit customer requirements. The main housing has one internal and one external earthing point. The heater element bundles are fitted within 50NB pipe thermowell tubes welded into the base plate of the main housing. The TWIH range are manufactured in the non stand-off welded base configuration.
 
SPECIFIC CONDITIONS OF USE: YES as shown below:
 
The flamepath length of the flanged cover joint is greater than the minimum values specified in Table 1 and Table 2 for Group I, Group IIB and Group IIB+H2. Heaters are manufactured for Group IIB+H2 requirements and may also to be marked for Group IIB and Group I applications with an increased cover flange gap of ≤0.20 mm.   Certificate to be marked with an X and condition of safe use required in accordance with clause 5.1 of IEC 60079-1:2007. Cover joint details shall be specified in the certificate in accordance with clause 5.1 of IEC 60079-1. Flamepaths also annotated in the operating and maintenance instructions.
