Schedule
 EQUIPMENT:
Equipment and systems covered by this certificate are as follows
 
 
The Range of TEE Flameproof immersion heaters are constructed from 316 stainless steel and consist of a single cylindrical main housing with a bolt on cover. Figure 1 in the annex lists the models in the range. The main housing is 280 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 flange. The cover is fastened to the rim of the 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 heater assembly has the option of being manufactured in either stand-off or non stand-off welded base configurations. The external surface temperature is controlled and limited by either a push button thermostat or RTD (with N322 digital controller) fitted within the heater enclosure. Table 2 in the annex lists the temperature classification and set points for the devices.


 SPECIFIC CONDITIONS OF USE:   YES as shown below:
 
 
- The M6 fastener used in the apparatus must have minimum yield strength of 1200 MPa. 

- Dimensions of flameproof joints are other than the values specified in Table 2 of IEC 60079-1:2007, and are listed in the manufacturer’s document EXM001.
