From lubricant blenders and asphalt producers to industrial manufacturers, Crystal Clean’s re-refined products deliver the performance, reliability, and consistency our customers depend on while supporting a cleaner and more sustainable future.
LDF – Light Distillate Fuel
Light Distillate Fuel (LDF) is a clean-burning fuel used across industrial and manufacturing applications. As a recycled, renewable product, LDF provides dependable energy output while helping customers reduce their reliance on virgin petroleum.
By capturing value from used oil, Crystal Clean’s LDF turns a potential waste stream into a practical, sustainable energy resource.
VTAE – Vacuum Tower Asphalt Extender
Vacuum Tower Asphalt Extender (VTAE) is a heavy, viscous product used in asphalt blending and road construction. It enhances pavement flexibility, durability, and performance, making it a preferred choice for asphalt manufacturers seeking a reliable, cost-effective solution.
VTAE replaces traditional virgin asphalt extenders with a re-refined alternative that lowers environmental impact without compromising quality to support a more sustainable infrastructure.
HTLF – Hydrotreated Low Flash Fuel
In Crystal Clean’s Hydrotreater Unit (HT), Hydrotreated Low Flash Fuel (HTLF) is produced as part of the re-refining process that upgrades Vacuum Gas Oil (VGO). This light, refined fuel is highly flammable and offers clean combustion with minimal odor, making it well-suited for industrial heating and blending applications.
HTLF delivers consistent performance while helping businesses minimize emissions and meet modern efficiency standards.
HTLS – Hydrotreated Low Sulfur Fuel
Hydrotreated Low Sulfur Fuel (HTLS) is anothe25198r fuel product from the Hydrotreater that meets stringent environmental requirements. With a significantly reduced sulfur content, HTLS provides an environmentally responsible option for commercial and industrial use.
Its stability and cleanliness make it ideal for customers seeking a balance between performance and compliance with clean fuel standards.
