High temperature range

up to 400 °C

In order to transfer operating temperatures above 355 °C heat transfer fluids with boiling points below the maximum operating temperature are normally used. While a conventional DP/DPO eutectic is indeed a solid at room temperature, it has very good viscosities compared, for example, to mineral-oil products. There are also products in the high temperature range which are still liquid at temperatures <0 °C and have good viscosities, enabling you to do away with trace heating.
