Castrol launches new hydraulic control fluid for subsea production systems
Castrol Transaqua SP-HC is suitable for Electro-Hydraulic Multiplex (EH-Mux) or direct hydraulic control systems in high-pressure, deep-water gas projects exceeding 20,000 psi (1379 bar), where entrained gas may contaminate control lines, creating a risk of hydrate formation.
