It is widely used in equipment for emergency stop systems and in equipment that must operate regardless of whether a fire occurs.
The Intertech proprietary composite material GRP structure technology allows the shelter to maintain an internal temperature below 60°C for 2 hours, even in the event of a hydrocarbon fire, thanks to the internal core made of rock wool and the external GRP layer. In the jet fire test, when exposed to external heat of 1000°C, it keeps the interior below 60 degrees for 120 minutes (2 hours). 【Application】 In the event of a fire, it is necessary to protect emergency "shutdown" (ESD) valves and their actuators from heat in chemical and petrochemical plants. During an emergency, the actuators must remain operable for at least 15 minutes after the fire starts. It is also possible to maintain operability under more stringent conditions of 30 minutes, 60 minutes, or longer. For these applications, we have developed a fire shelter that has been certified by a third-party organization in compliance with UL 1709, and it is patented.

Company information
Protecting internal equipment from environments such as cold, heat, corrosion, and chemical areas. Founded in Germany in 1965, our company has a history of 50 years and has achieved an annual growth of 15%. The reason for this growth lies in our unique GRP material. As experts in GRP material, we manufacture enclosures, cabinets, and shelters, while simultaneously providing heating and cooling systems installed inside. We are a German manufacturer that offers diverse solutions to protect delicate field equipment in chemical plants, petrochemical plants, and other industries worldwide. We protect internal measurement, control, and analysis equipment from environments such as freezing, excessive heat, corrosion, and condensation. All of our products are made from GRP (glass-reinforced polyester) material, which has a very low thermal conductivity, allowing us to maximize the efficiency of cooling and heating systems. 【ISO Certification】 ISO 9001 ISO 14001
