Safety has been and will continue to be the most important design factor in our development projects. ROX Cylinders produced by Hexagon Ragasco are manufactured per the Lebanese Standard NL ISO 11119-3 issued by LIBNOR; the Lebanese Standard Institution. Moreover, physical check and testing procedures was conducted by the Lebanese Industrial Research Center, LIRI, through actual visits to Hexagon Ragasco factory in Norway and through testing after production upon arrival to the Lebanese Customs.
For the European Union, our composite LPG cylinders have been approved according to ADR/RID and are marked with the Pi-mark according to the TPED Directive. Hexagon Ragasco works with the German organization TÜV as approval partner. The European approval is based on the requirements of EN 12245 and EN14427 (equally valid - see the paragraph "Approval). In USA, our cylinders are approved according to DOT Special Permit 12706 and by TC Permit For Equivalent Level Of Safety SU 5931 for Canada.
We have achieved outstanding results on the market, where over 12 million units have been manufactured and in use over 15 years. Customers and users are extremely pleased with the performance and handling of our products.
ROX Cylinders do not rust, corrode, or break down because of their ECO Friendly composition. In case of fire, our cylinders will not BLEVE (Boiling Liquid Expanding Vapor Explosion) thus no more concerns for cylinder explosions. Instead, the resin will burn off and the plastic liner and casing will melt. The LPG will then “breathe” through the cylinder wall and burn in a controlled manner.

  • Layer 1: The blow-moulded liner (HDPE) is the seamless gas barrier layer with a boss for mounting the valve onto the cylinder. The boss is made of injection-moulded HDPE with a brass insert.
  • Layer 2: This composite load-carrying material is filament-wound fibre-glass and resin which has a tremendous capacity to withstand pressure. An advanced curing process ensures the see-through feature.
  • Layer 3: The distinctively designed, injection-moulded outer casing protects the pressure vessel and valve. The ergonomic handles allow easy lifting and are built for stacking. For more information see Technical Specifications.

The HDPE liner and composite pressure vessel have sufficient translucency for the user to see the liquid level of LPG inside the cylinder. The translucency feature enables the user to see the gas level through the wall of the cylinder, therefore eliminating the risk of running out of gas at an inopportune time. It also makes it possible for the consumer to verify that the cylinder has actually been filled with the right amount of LPG.

Our cylinders do not corrode. All applied materials are non-corrosive and have been carefully selected to ensure maximum chemical stability and resistance to concentrations of acids or solvents that may appear in the LPG or in the environment where the LPG cylinders may be stored or used. Additionally the pressure vessel is protected by a coating on the outside.

For visual purposes, ROX cylinders can be easily and inexpensively cleaned by power-washing with a soap and water solution. Therefore, shot-blasting or painting of the cylinders IS NOT needed. For mandatory reconditioning, please see the paragraph Retesting below.

Our marking is approved by the Lebanese Industrial Research Center (LIRI) and the Directorate General of Oil in Lebanon. In brief, our cylinders are marked with serial number, approval marking/number, approval authority ID, country of origin, manufacturer ID, volume, and weight.

ROX cylinders are equipped with 3 traceability features: Serial Number, QR Code, and RFID. Thus ROX will be corporate logo or other customer-specific markings. The cylinders may also be fitted with RFID/transponder chips. Hexagon Ragasco will supply the customer with a database file corresponding to each cylinder lot.

Our Cylinders are tested and approved down to -40C. The use of LPG in low temperatures is, of course, limited by the vaporization capability of the specific LPG mix. Normally the casing will have no damage at low temperature if handled correctly, but it is less resistant to significant impact if handled severely.

Our Cylinders are designed to withstand temperatures well above 65°C. Long-term use in hot climate shows that the cylinder is not affected and remains safe to use in these extreme climates. Our cylinders have already been in use several years in countries consisting mainly of desert and where temperatures can easily reach above 50°C in the shade on a regular basis.

The materials in the cylinders from Hexagon Ragasco have been carefully chosen. One of the great benefits of the selected materials is that they are unaffected by salt and humidity. Corrosion does not occur and therefore the cylinders are well adapted for use in hot, humid and saline environments.

As stated above, the applied materials have been chosen for different considerations. One of them is to ensure maximum UV stability. In addition, UV additives are applied to the casing material depending on the geographic zone where the cylinders are to be used.

Re-testing is based on the Lebanese Specifications NL ISO 11119-3 that specifies a retesting interval of 10 years. Furthermore, Hexagon Ragasco is the only composite cylinder manufacturer to have achieved a 15-year interval for the first inspection of cylinders in Denmark, Finland, Norway and Sweden.

The outer casing of the cylinders allows for certain color variations. The standard for the lower part is light grey. The upper part and the top ring can be supplied in a wide variety of colors. The current standard colors are:

  • Dark grey
  • Green
  • Red
  • Yellow
  • Blue
  • Orange

In Lebanon, ROX Composite Cylinders passed all required testing procedures and the use of ROX Cylinders manufactures per NL ISO 11119-3 which was set by LIBNOR has been approved by the Directorate General of Oil, Ministry of Energy, and Ministry of Industry.
Moreover, Composite cylinders are approved for use in over 40 countries. This includes and is not limited to the following: all EU countries, USA, Canada, Middle East (Qatar, KSA, UAE…), Africa, Philippines, Australia and many other countries.
