Industrial Fire & Thermal Asset Protection
HomeFire Sealing Guide

MCL Unitex Ltd, a member of the ISL Group of Companies, is a specialist manufacturer of flexible passive fire protection systems and has extensive experience in the design, testing, construction and installation of fire seal systems and fireproof enclosures for the oil, gas, petrochemical and refining industries worldwide. Our experienced engineering staff may also be called upon to design bespoke systems and to further manage testing and certification.

MCL Unitex seal and enclosure systems are independently tested by IMO-approved third party test houses. Throughout testing MCL's systems have maintained their integrity, stability and insulation properties, and accordingly carry certification issued by Lloyd's Register of Shipping and Det Norske Veritas (DNV).

In addition to hydrocarbon furnace fire testing, the Firetex range of penetration seal systems have been subjected to independent blast over-pressure testing and have proved their ability to maintain stability and integrity in blasts of up to 1.35bar g. More recently, following the establishment of an internationally approved test methodology, our systems have been subjected to jet fire testing and carry further approvals up to J120.
