UNITOR COMPATIBILITY TEST KIT

Product group:: 663
Product number:: 773153

Understanding the stability and compatibility of your fuel is critical for safe and efficient operations. At the point of bunkering, however, it is often difficult to determine the fuel’s actual condition, particularly its stability, potential incompatibility with existing onboard fuel, and whether any treatment is required to maintain its integrity. The Unitor Compatibility Test Kit allows you to quickly and reliably assess both the stability and compatibility of bunkered fuel. By identifying unstable or incompatible fuels early, the test provides reassurance when results are satisfactory and, more importantly, gives you valuable time to take corrective action before the vessel departs port.

Product information

This product supersedes product no: 555755

The Unitor™ Oil Compatibility Tester is an effective solution for verifying the stability and compatibility of all marine fuels, including HFO, VLSFO and Bio-VLSFO. It enables crews to quickly assess whether a fuel is at risk of asphaltene sludge formation, one of the key indicators of instability and incompatibility. Designed for simple and rapid onboard use, the tester provides a practical way to evaluate whether fuels can be safely mixed or blended, particularly when handling residual fuels. By delivering a clear picture of both fuel stability and compatibility, it helps operators make informed decisions, avoid operational issues, and maintain fuel integrity throughout the system.
