INTERTEC offers an extensive range of fire-resistant shelters, including ‘1709’ models designed to protect critical safety equipment from exposure to high-temperature fires in hazardous areas.
The shelters are entirely passive, maintenance-free and impervious to a wide range of corrosive chemicals, including salt, sulphur dioxide and sour or acid gas.
Typical applications for the 1709 versions include protecting valves and actuators in the emergency shutdown and firefighting systems of refineries and chemical plants, in addition to offshore oil and gas production platforms.
Another key application for INTERTEC’s fire protection materials is separating hazardous and non-hazardous areas on ships and on offshore drilling, processing and storage platforms. This development will be of considerable interest to designers seeking a means of meeting the future IEC 61892-7 standard for offshore platforms and vessels, which will demand area separation materials capable of withstanding a hydrocarbon fire for between 60min and 120min as defined in UL 1709.
INTERTEC has extensive experience of fire resistant shelters, having produced models tested in accordance with the German DIN 4102-2 standard for 20 years. Throughout this period we has continually improved materials and construction techniques to meet more challenging specifications, culminating in a new patented design that keeps contained equipment below 60°C (140°F) for 90min, even during ‘rapid rise’ hydrocarbon fires that can reach 1,093°C (2,000°F) within five minutes. This level of protection is believed to be unique for passive fire shelters – many competitive models only specify 30min of protection.
