Bulk Diesel Exhaust Fluid (DEF) for Fleets & Commercial Operations

Keep your diesel equipment running with BlueDEF Diesel Exhaust Fluid from Keller-Heartt. Shop DEF in 2.5-gallon cases, 55-gallon drums, and 275- or 330-gallon totes for individual vehicles, shops, fleets, and high-volume commercial operations.

BlueDEF is designed for diesel vehicles equipped with Selective Catalytic Reduction (SCR) systems and meets ISO 22241 standards for DEF purity and composition.

Choose the Right DEF Size for Your Operation

How much DEF you need depends on your equipment, fleet size, and how frequently you're refilling. Keller-Heartt carries multiple package sizes so you can purchase DEF based on actual usage instead of taking a one-size-fits-all approach.

2.5-Gallon BlueDEF Cases

A convenient option for individual diesel vehicles, smaller shops, and keeping backup DEF on hand. The smaller container size makes it easy to store and refill vehicles as needed.

55-Gallon BlueDEF Drums

For shops and smaller commercial fleets that use DEF regularly, a 55-gallon drum provides more capacity without requiring the space of a full tote. Keller-Heartt's BlueDEF 55-gallon drum is one of its best-selling DEF products.

275-Gallon BlueDEF Totes
