Castrol Alpha HC Range (previously called Isolube Range) lubricants provide excellent performance in circulating oil and gear set applications. Alpha HC lubricants contain technically advanced chemistries that exceed the performance levels historically attributed to the traditional synthetic products. Alpha HC lubricants excel in applications requiring optimum oxidation control and thermal stability, consistent anti-wear performance, and low carbon forming tendencies. The uniqueness of the Alpha HC Lubricants is most visible in compressors that operate under severe field and industrial conditions.
When compared to coventional gear lubricants:
