Common questions – information

What is the accuracy of the gas Mixture?
The accuracy is as follow and is depending on the size of the cylinder

  • 12 ltr cylinder
    • For mixtures up to 99 ppm ±10%
    • For mixtures more than 100 ppm ±5%
  • 34, 58, 110 ltr cylinder
    • For mixtures 5-49ppm +/-10%
    • For mixtures 50-500ppm +/-5%
    • For mixtures > 500ppm +/-2%

What sizes of gas mixtures are you promoting?
There are many sizes of non refillable gas cylinders depending on the application in which you would like to use it

  • 5 ltr Steel
    • Size : 65 X 181 mm
    • Pressure : 8 Bar
    • Material : Steel
    • Capacity : 5 ltr content
    • Gas Handling: Aerosol
  • 12 ltr Aluminum
    • Size : 230 X 78 mm Dia
    • Pressure : 12 Bar
    • Material : Aluminum
    • Capacity : 12 ltr content
    • Gas Handling: 7/16″ 28NS/2 ma
  • 34 ltr Aluminum
    • Size : 230 X 73 mm Dia
    • Pressure : 34 Bar
    • Material : Aluminum
    • Capacity : 34 ltr content
    • Gas Handling: 5/8” – 18 UNF (C10)
  • 58 ltr Aluminum
    • Size : 360 X 88 mm Dia
    • Pressure : 34 Bar
    • Material : Aluminum
    • Capacity : 58 ltr content
    • Gas Handling: 5/8” – 18 UNF (C10)
  • 110 ltr Aluminum & Steel *
    • Size : 360 X 88 mm Dia
    • Pressure : 68 Bar
    • Material : Aluminum
    • Capacity : 110 ltr content
    • Gas Handling: 5/8” – 18 UNF (C10)

*Aluminum cylinders at 110 ltr are used in reactive gases and steel cylinders in non reactive gases

How should I dispose the non refillable cylinders?
All SpecCans are non-refillable, once empty they can be shipped or disposed of as non-hazardous waste through the normal waste streams, check any local legislation

What type of regulator will I need?
The type of regulator is depending on the size of the cylinder and the mixture. Our technical department will propose the suitable regulator for your application
