The PROTEGO® flame arrester unit PROTEGO® flame arrester unit The PROTEGO® flame arrester unit is the main component of a flame arrester. It prevents flame propagation. consists of several FLAMEFILTER® discs firmly held in a housing Housing A housing is a solid shell, which surrounds a content, either protecting the content from external influences, or protecting the environment from the content. . The gap size and number of FLAMEFILTER® discs are determined by the operating data and parameters of the mixture flowing in the line ( explosion Explosion Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. group, pressure, temperature). To provide an optimum result between the housing size, number of FLAMEFILTER® discs and their gap size, a device Device A device is a pipe component that influences the media flow by opening, closing, or partially shutting off the flow channel or by dividing or mixing the media flow. was developed that can be used for all explosion groups - IIA, IIB3 and IIC (NEC Group D, C MESG ≥ 0.65 mm and B). The standard design can be used with an operating temperature Operating temperature Temperature reached when the equipment is operating under design conditions. of up to +60°C / 140°F and an absolute operating pressure Operating pressure Operating pressure is the pressure existing at normal operating conditions within the system being protected. up to 1.1 bar / 15.9 psi. Devices with special approvals for higher pressures (see table 3) and higher temperatures are available upon request.
