Heat Transfer Oils


Name Characteristics performance standards/Approvals
CREST Protherm B

High Quality Heat transfer mineral oils to be applied from -10 °C up to +315 °C and used for closed systems, equipped with an expansion tank. The low vapour pressure of this oil implies a low volatility by which system pressures can be kept low. It has a low viscosity and a high coefficient of heat conductivity, providing a maximum heat transfer.

DIN 51522-Q
CREST Protherm AB

Synthetic (Alkyl benzene based) organic transfer fluid intended for use in applications that require liquid phase heat transfer. It can be used in non-pressurized or indirect systems. The optimum maximum use temperature of this oil is 330 °C
