Castrol Perfecto HT 5 (ex BP Transcal N)
Operating temp: up to 300C

Description Instructions Sizes, Prices & Offers

Castrol Perfecto HT5 (formerly known as BP Transcal N) is a heat transfer oil based upon highly refined mineral oil, selected for its high thermal stability, resistance to oxidation and low volatility.


Castrol Perfecto HT5 is primarily intended for use in enclosed and sealed systems where oxidation of the oil cannot take place as contact with air has been prevented. In such systems maximum bulk temperatures of 300C (film temperatures up to 320C) are permissible.

Usage notes

Systems are normally designed so that the only contact between the oil and air is in a header tank where the oil is relatively cool and the area of the exposed oil surface is limited. Although the inherent oxidation stability of this oil is high, it should be realised that the working life of the oil depends to a considerable extent on the effectiveness of the measures taken to exclude air. In open baths the oil will oxidise rapidly at temperatures much in excess of 100C.

Castrol Perfecto HT5 is a low viscosity oil for high velocity circulating systems - high flow rates allow high heat transfer rates.
