Description

Castrol Perfecto™ HT Range (previously called Heat Transfer Oil Light 100 and Heat Transfer Oil 1590) are formulated from very stable paraffinic base oils that are fortified with high temperature oxidation inhibitors that carry away heat from critical components. Perfecto HT’s 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).

Advantages
Perfecto HT 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.
Perfecto HT 4 (Heat Transfer Oil Light 100 Light) is recommended for application in closed circulation systems with temperatures up to 287° C (550° F). Perfecto HT 4 is particularly applicable where high transfer rates or good flow rates at fairly low temperature are desired.
Perfecto HT 5 Plus (Heat Transfer Oil 1590) is recommended for application in closed circulation systems with temperatures up to 315°C (600° F).
