Looking for recommendations for suitable inert refrigerants
Thread Content
Purpose: Used as a heat transfer medium, with an operating temperature range of -30 to 100°C. It requires a high specific heat, low viscosity, and must be non-flammable and non-explosive. (Used as a reagent for heat exchange during the preparation process; it must be free of water and must not react with the substances involved in the reaction.)
Low-temperature heat transfer oil can be used for this purpose. Previously, an expert recommended an imported product; I can’t remember its name now. The information on http://zhan0421.xunshou.com/ indicates that it can be used in temperatures ranging from -130 to 190 degrees
