Test Inergen™ System Pressure Loss Non-Invasively.
As market leaders for 30 years in testing liquified gaseous suppression systems such as CO2 & NOVEC® 1230, we spent 4 years developing a non-invasive solution for measuring pressurised, non-liquid inert gas systems and we now bring you Portagas®.
The first of its kind. To monitor inert gas cylinders such as Inergen™, easily and quickly in an intuitive Android platform.
The Portagas® detects minor changes in internal pressure, with precision comfortably exceeding the 5-10% agent and pressure loss thresholds cited in regulations such as NFPA 2001 and ISO 14520.
Intuitive: Know whether an observed change in pressure is due to changing temperatures or a loss of contents..
Reporting: Save your maintenance records, organised by date, time, site and cylinder.
Export data: Export your maintenance records as a CSV file or PDF report, via email or USB and enhance your service reports.
Regulation Compliance: NFPA 2001 & ISO 14520-1.
Inergen™ or Inert Gases are stored in seamless cylinders at pressures between 100-200 Bar. At such pressures cylinders are subject to slow seepage of contents or accidental discharge. If the gas available is not at the design concentration- the fire will not be extinguished.
Pressure alone does not tell the full story. To understand the status of a cylinder’s contents, we must consider the pressure and temperature together. This is because in a sealed container pressure is directly related to temperature. So, a change in temperature does not always mean that the cylinder has leaked.
Conventional pressure gauges typically address this by indicating a range of acceptable pressures based on different temperatures. This is a useful indication; however, these ranges are broad and open to user error.
The Portagas® tackles this issue head on, with an infra-red thermometer built into the sensor to record the temperature correctly. This temperature, combined with Fill Pressure and Fill Temperature (printed on the cylinder) precisely determines the current pressure. Portagas® calculates this automatically with no user input.
This temperature-adjusted pressure is then compared with the pressure determined acoustically by the Portagas®. This allows it to recognise if a change in pressure is due to changing temperatures or loss of contents, all with the tap of a finger.
Portagas® is the only way to get a true status on the cylinder contents.
