Castrol Perfecto™ HT 5 is based on a solvent-refined, high viscosity index mineral oil specially selected for its high
thermal and oxidation stability.
Perfecto HT 5 is primarily intended for use in closed heat transfer systems with bulk temperatures up to 300ºC. It can
also be used in open systems at much lower bulk oil temperatures.
Perfecto HT 5, because of its solvency and high thermal stability serves as excellent Turbine Flushing oil.
- Tightly controlled specification helps minimise deposits in heat exchangers in order to maintain heat transfer efficiency
High operating temperature capability in closed systems with temperatures up to 300oC permitted
All packages should be stored under cover. Where outside storage is unavoidable drums should be laid horizontally to avoid the possible ingress of water and the obliteration of drum markings. Products should not be stored above 60oC exposed to hot sun or freezing conditions.
