ZONE 0 Hazardous Gas Detector

The Hazardous Gas Detector protects process rooms and other locations where Methane, Natural gas, Propane , or Hydrogen may be present by monitoring hazardous gas levels. For Meth-ane, concentrations of 5% to 15% mixed with air can be explo-sive. Sparks or hot surfaces can ignite them. The Methane gas detector will provide a warning and facilitate dissipation of the hazardous gas, by operating alarms and exhaust fans before it reaches the lower explosive limit of 5%. The Alarm is set for 1%.

In addition to protecting your property and employees, cost savings are also realized. Explosion Prevention Syst ems (NFPA 69) prevent downtime. I nsurance premiums may be reduced as a result of a Methane gas detector installation. Electricity costs decrease as a result of controlled exhaust fan operation rather than continuous fan operation. Air conditioning and heating costs are also reduced as a result of the controlled fan opera-tion.

Three models are available in AC ; Methane, Hydrogen, and Propane
