Description

Therminol® VP-1 is a thermal oil for very high temperatures and has excellent thermal stability. Therminol® VP-1 is designed for temperatures up to 400 °C and can be used in both the gas and liquid phases of a thermal system. The system requires a static pressure of about 10 bar to operate in the liquid phase at high temperatures.

Therminol® VP-1 is a eutectic mixture of 73.5% diphenyloxide (DPO) and 26.5% diphenyl (DP) and as such can be used in both gas and liquid phase systems. Gas phase operation is possible at temperatures above 275 °C. Since Therminol® VP-1 already solidifies at + 12 °C, it is important to provide the installation parts with “tracing” (heating of the piping system) to prevent the oil from solidifying in very low weather conditions.

We recommend that you read the Therminol® VP-1 product brochure carefully.
