Product Details

Improve Cold-Weather Performance in Biodiesel Blends

Biodiesel blends can begin experiencing cold-weather flow problems at significantly warmer temperatures than conventional diesel fuel. As temperatures fall, wax crystals and other naturally occurring components in biodiesel can restrict fuel flow, plug filters, and reduce equipment reliability.

Bio Cold Flow Improver is specifically formulated to improve the low-temperature performance of B20 and higher biodiesel blends, helping maintain fuel flow and reduce cold-weather operability issues before they become costly downtime.

Ideal for fleets, fuel distributors, municipalities, agricultural operations, marine operators, and facilities storing or using higher-concentration biodiesel blends during colder weather.

Improves Cold Flow Properties

Bio Cold Flow Improver works by modifying the formation and growth of wax crystals within biodiesel blends. Instead of forming large crystals that quickly restrict fuel flow, the treated fuel maintains improved flow characteristics at lower temperatures.

This helps fuel move more freely through storage systems, transfer equipment, filters, and engines during cold-weather operation.

Helps Prevent Filter Plugging

Cold-weather filter plugging is one of the most common operational problems associated with biodiesel blends.

By lowering the Cold Filter Plugging Point (CFPP), Bio Cold Flow Improver helps reduce the likelihood of fuel starvation and filter restriction that can interrupt equipment operation during colder conditions.

Improves Low-Temperature Operability

Bio Cold Flow Improver helps improve the overall cold-weather performance of biodiesel blends by:

  • Lowering the Cold Filter Plugging Point (CFPP)
  • Lowering the fuel's pour point
  • Improving fuel handling during storage and transfer
  • Supporting reliable equipment operation in cold weather

Regular treatment helps maintain consistent biodiesel performance throughout winter storage and operation.
