Type ELK-MI AY 825 Single Conductor
High Temperature Mi Type Minerel Insulated Cables - Type ELK-MI AY 825 Single Conductor
MI-trace heaters consist of a single conductor series trace heater connected to mineral-insulated cold leads by means of a clean laser seal (splice). The outer sheath material is Alloy 825.
Type ELK-MI AY 825 Single Conductor
MI-trace heaters consist of a single or two conductor series trace heater connected to mineral-insulated cold leads by means of a clean laser seal (splice). The outer sheath material is Alloy 825. The free end of the cold lead is potted and fitted with a flexible lead (cross section matching that of the cold lead conductor) for power connection and a 1.5 mm² (0,002325 in²) lead for earthing. A compression ring flameproof stainless steel gland 1.4404 (AISI 316L) threaded M20x1.5 or M25x1.5 is fitted at the end of each cold lead and prevented from possible loss by the potted end seal. MI trace heaters are supplied prefabricated by eltherm and ready for installation. Each unit comes with a type plate bearing all information / markings. Maximum maintain temperatures are derived from the maximum sheath temperature determined by eltherm and are also indicated on the type plate.
Applications:
- Chemistry and Petrochemistry
- Oil and Gas Industry
- Industrial processes
- Mobile processing facilities
- Vacuum processes
- Temperature maintenance
- Silos, vessels, tanks
Benefits:
- 100% homogeneous design in premium Alloy 825
- No filling holes
- Single and Twin design
- High temperature resistance
- Maximum resistance to chemicals (chlorides, etc.)
- High power output
- Protection against stress corrosion
- Sea water-resistant, maximum corrosion resistance
Approvals:
- Classification: II 2 G Ex 60079-30-1 db eb IIC Gb, II 2 D Ex 60079-30-1 tb IIIC Db
- Certification: FM15ATEX0046X, FM18US0191X, FM18CA0089X, IECEx FME 15.0009X
