Compact AVSU Module

  • The AVSU can be installed as a flush or surface mounted.

  • Gas Identification is located on the body of the AVSU behind the window and is immovable.

  • A large viewing window to the door gives an immediate indication of Gas Identification located on the body of AVSU, valve position, and flow direction.

  • In an emergency, this can be gained by pulling the window thus allowing access to the valve. The anti-tamper device can be fitted to the window and connected to our Digital Alarm and BMS to incorporate monitoring of all CPX AVSU’s.

  • Non-interchangeable NIST connectors are fitted upstream and downstream of the valve. Including 100% sealing serviceable non-return valves to allow the pipeline to be pressure tested and provide an easily accessible point for gas sampling.
