Chemola™ Desco 111 (LT)
Low Temp Hydrogen Sulfide Service
Chemola™ Desco 111 (LT) is designed for use in valves under arctic conditions (to -75 F). 111-LT is extremely resistant to hydrogen sulfide and will not mix with water, preventing freeze-up in the valve. Because it provides good metal protection and is particularly water resistant, it is the recommended lubricant for frac valves.
Recommended Uses
Chemola™ Desco 111-LT can be used in the presence of diesel fuel, gas and well condensate, hydrogen sulfide, CO2, sour crude and standard crude. Recommended for frac valves.
