Arctic Grade Diesel (“Arctic”)

Standards:
EN 590 Arctic (Class 0–4) / Cold-Climate Diesel
Description:
Specialized low-temperature fuel engineered with enhanced cold-flow properties and a Cold Filter Plugging Point (CFPP) down to -38°C. Prevents wax gelling and filter clogging, ensuring uninterrupted cold starts and reliable equipment performance under extreme winter conditions.
Key Applications:
Severe winter logistics, critical backup generator systems, off-highway machinery operating in freezing conditions.

Winter & Arctic Diesel Transition Guide

Cold Filter Plugging Point (CFPP down to -38°C) guidelines and fuel gelling prevention

Cold Filter Plugging Point (CFPP): Strict seasonal adjustments to prevent paraffin crystal formation (waxing) that clogs fuel filters.

  • Summer Grade: CFPP up to 0°C or -5°C.
  • Winter / Arctic Grades: CFPP down to -15°C, -20°C, or lower depending on regional temperature drops.
