ComplianceStandards : CTL – PT / SR/ ZH to EN 62395-1 and CTL – PT to EN 60079-0, EN 60079-30-1 & EN 60079-31.
ApprovalsCTL-PT: Tested by Central Institute of Mining and Fuel Research (CSIR-CIMFR), Dhanbad And certified by Petroleum & Safety Organization (PESO) / Nagpur, for Zone II , TI (ATEX) for Zone I / Division II & EAC for use in hazardous area applications.

CTL – PT / SR/ ZH : CE and EAC

Rugged constructionOuter metallic braid in CTL – PT & CTL – SR makes it robust and suited to hostile conditions.
Chemical ResistantFluoropolymer insulated Thermotrace CTL is inert to all chemicals, and it is waterproof and weatherproof.
Long LifePTFE has excellent electrical properties, thermal stability, fire resistance and is virtually non – ageing and can withstand the high temperature continuously.
Efficient Heat TransferFlexible and flat configuration of the Thermotrace CTL enables an intimate contact with the surface to be heated, ensuring efficient heat transfer.
Cut to LengthThermotrace CTL is supplied in continuous long lengths, which can be cut to desired lengths.
Custom builtWe also offer custom designs of a product to suit individual requirements. We can design for various dimensions and voltages.


Depending on the application and site conditions (viz. temperature, weather conditions, chemical environment), we can offer options of various insulating materials for Thermotrace CTL to match your individual requirements.
