Flashback Arrestor 85-30 SMART

WITT Flashback Arrestors for reliable protection against dangerous reverse gas flow and flashbacks according to DIN EN ISO 5175-1, combined with high-tech sensors and electronic components.
Every Arrestor 100% tested.
The Flashback Arrestor 85-30 SMART indicates via LEDs its current status. The signal is then transmitted to a control system. Status is communicated in real-time.
This is key contribution to accident prevention and process.

Features of Flashback Arrestor 85-30

• according to PED 2014/68/EU, connection G1.1/2 category I
• available in brass or stainless steel (ES)
• a large surface area flame arrestor FA of stainless steel construction extinguishes any dangerous flashback
• a temperature sensitive cut-off valve TV extinguishes sustained flashbacks long before the internal temperature of the arrestors reaches a dangerous level
• a spring loaded non-return valve NV prevents slow or sudden reverse gas flow from forming explosive mixtures in the gas supply
• a filter at the gas inlet protects the arrestor against dirt contamination, extending the service life

Smart Features

• any flashback or backfire is detected electronically and recorded as a timestamped event
• four LEDs provide a visual all-round indication of normal operation, flashback, backfire, hardware faults and low battery via red/green/yellow/blue diodes located directly on the safety device
• digital signal via a NPN open collector signal or RS485 for transmission to a control system
• reset button on the safety device for resetting or acknowledging the system following a flashback or backfire
• connection M8, 4-pin plug for signal cable 5 m (Art.-No. 803097000)
• not suitable for use in hazardous areas

Benefits

• immediate detection of flashbacks and backfires
• early detection of sources of faults before other downstream system components are damaged
• planning framework for optimised maintenance work
• minimises downtime, increases service life – reduces operating costs
• maximum protection for staff and facilities
