Function and Description

Main component - PROTEGO® flame arrester

The PROTEGO® EB-IIA consists of 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. (1) and the metal weather hood Weather hood A weather hood is a cover to protect the internal components of a device from environmental influences. (2). During normal operation, the metal weather hood is in a closed position. If a stabilized flame burns on the flame arrester element surface, the melting element Melting element The melting element is a component that consists of a housing with a lower and upper part. (3), located in a center position, will melt and let the spring Spring A spring is a spiral of wire which returns to its original shape after it is pressed or pulled. -loaded weather hood move into the open position. The PROTEGO® flame arrester unit consists of one or more FLAMEFILTER® (5), which are installed in a FLAMEFILTER® casing FLAMEFILTER® casing Enclosure for FLAMEFILTER® including insert rings. (4), a fixation element (6) and an insert ring (7).

For Explosion group IIB and IIA

The FLAMEFILTER® gap size, height, and quantity depend on the device’s intended use. The PROTEGO® EB series end-of-line deflagration flame arrester is available for substances from explosion Explosion Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. group IIA and IIB (NEC group D 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. Devices with special approval for higher temperatures are available upon request. EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
