Exol expands coolant range with Opticool Orange
10 October 2025 
Exol Lubricants has expanded its products line with the launch of Opticool Antifreeze Orange (D052), a high-performance heavy-duty engine coolant.
Free from nitrites, amines, phosphates, borax & silicates, the latest addition delivers advanced protection, extended service life and excellent system compatibility, Exol said.
The coolant’s sophisticated inhibitor package ensures outstanding corrosion resistance across all metals and alloys used in modern cooling systems, particularly aluminium. It also includes a neutralisation package to combat the adverse effects of brazing flux used during the manufacture of aluminium heat exchangers, extending component life and reducing maintenance requirements.
Opticool Antifreeze Orange is suitable for a wide range of heavy-duty and OEM applications.
