The DIMES Digital Measurement System for inert gas
Mar 29, 2017
Rotarex Firetec has achieved a breakthrough innovation called DIMES that ensures the readiness of an inert gas system with 99.9% accuracy — and sends a notification in case of a leak.
The DIMES Digital Measurement System for inert gas

For inert gas to effectively suppress a fire, the correct amount of gas needs to be released to displace the oxygen level below 15%. Should a leak occur, the system can fail. However, traditional methods that rely on cylinder pressure to calculate cylinder contents can give "false reads." Since this pressure can vary with changes in temperature, there is a risk of a fire protection system failure. When the temperature is hot, increased pressure made hide the fact that there is a leak and not enough gas in the cylinder. Conversely, cold temperatures can trigger false alarms.

DIMES is the first to be able to adjust for temperature variations on pressure to deliver a precise real gas reading. Using advanced algorithms and gas behavior data, the Rotarex Firetec development team calculated the real gas dynamics at every temperature. This delivers an extremely accurate reading of cylinder contents at all temperatures.

  • User-friendly interface
  • Traceability
  • Export to external devices
  • 0 to 400 bar

DIMES is provisioned with robust traceability protocols that include data relative to each cylinder, such as date of service and maintenance schedules. Replacing traditional pressure gauges with the new digital DIMES IG system gives users confidence that their inert gas fire suppression system is fully pressurized and will not fail at the critical moment. It will be ready at all times, 24/7/365.
