WITT 85-30 SMART flashback arrestor

The WITT 85-30 SMART flashback arrestor offers an active monitoring function: the fitting not only stops flashbacks and backfires, but also detects them and immediately provides the information as a signal.

This changes the arrestor from a passive safety component into an active sensor within the gas system. Monitoring enables an immediate response to irregularities and lays the foundation for a stable, safe process. Personnel, plant and system components are protected even more effectively, and service life can be extended.

Technically, the SMART version is based on WITT’s existing 85-30 flashback arrestor. This features a flame arrestor made of sintered stainless steel, a temperature-controlled backflow preventer, a gas non-return valve and an integrated dirt filter. It is available in brass or stainless steel and is suitable for numerous gases such as acetylene, hydrogen, natural gas, liquefied petroleum gas and oxygen.

The 85-30 complies with the requirements for safety devices in accordance with DIN EN ISO 5175-1. The high reliability of the fitting is confirmed by external certification from the IBExU Institute.

Due to its signal transmission capabilities, the 85-30 SMART is more suitable for modern, digitally networked production environments, supporting the digitalisation of gas supply systems.
