Heat Transfer Fluids

Castrol Heat Transfer Oils are formulated from very stable paraffinic base oils that are fortified with high temperature oxidation inhibitors that carry away heat from critical components. Castrol Heat Transfer Oils’ high viscosity index coupled with a low pour point offers excellent circulation during cold weather startups, eliminates heat from over heated pump motors, and protects against hot spots (high fluid temperature in the heat exchanger). Features and Benefits Castrol Heat Transfer delivers: ??? Low vapor pressure at elevated temperatures and a high boiling point to prevent pressure build-up ??? Low carbon residue ??? Non-foaming and excellent demulsibility. ??? Long shelf life. Castrol Heat Transfer Oil 100 Light recommended for application in closed circulation systems with temperatures up to 287° C (550° F). Castrol Heat Transfer Oil 100 Light is particularly applicable where high transfer rates or good flow rates at fairly low temperature are desired. Castrol Heat Transfer Oil 1590 recommended for application in closed circulation systems with temperatures up to 315°C (600° F).
