From Australia to the world

The Refrigerant Oil Company (ROC) explains it pioneered the use of PAO-based oils in refrigeration 20 plus years ago
Thanks to that work, ROC says PAO-based lubricants are now accepted worldwide for air conditioning applications, including for cabin climate control in electric vehicles, with many companies following ROC’s lead globally.
The users of ROC products reportedly recognise the advantages of the stability, purity and lubricity of Polyalphaolefins (PAO) for the AC service industry, and now added to these benefits, the electrical properties of PAO make it suitable for the high voltage electrical systems in EVs.
After continuous development, the updated ROC formulations are now sold under the Ariazone brand in Australia through all major aftermarket outlets. Fluorescent versions are also available to assist in system leak detection.
Although blended and formulated in Australia, Ariazone oils are now used in over 40 countries, including the latest release, the VG 46 series of oils (PAOIL AA4). VG 32 (PAOIL AA2), VG 68 (PAOIL AA1) and PAOIL PL68 are also still available.

ROC says there are many reasons why you should consider using PAOIL in your workshop, including:
• Usable with all automotive compressor types including hybrid vehicle compressors.
• Compatible with R134a and R124-4yf refrigerants.
• Suitable for use in hybrid and electric vehicles (AA series is preferred but PL series may be used).
• A high viscosity index means the oil maintains its viscosity and lubricating properties at high operating temperatures.
• Unlike other lubricants, PAO is non-hygroscopic – it does not readily absorb moisture.
• Due to the inertness and inherent stability of PAO, PAOIL has a five-year shelf life.
• Available with an added UV dye to help with leak tracing.
• Safe to use – PAOIL is a non-hazardous, non-toxic product which is safe to have around the workshop.

ROC says the PAOIL PL series offers the same properties as the PAOIL AA series, meaning it can be used as a complete oil replacement for A/C systems.
The company adds that by using PAOIL you can buy in bulk (PAOIL is available in 1L, 5L and 20L container sizes) and with its five-year shelf life, you need not worry about the oil being unusable a couple of hours after opening.
Ariazone and ROC are fully Australian-owned companies based in Melbourne at its Global Headquarters and are part of the ROC Group.
Ariazone/PAOIL products are currently used in workshops in more than 40 countries worldwide.
