Ultrahigh-temperature, vapor/liquid phase fluid to 400C
Therminol VP-1 has a low viscosity between its melting point (12°C/54°F) and the temperature at which it vaporizes (257°C/495°F). In geographic areas where the system may be exposed to temperatures below this level, all piping that may contain the fluid in its liquid state should be heat traced. The recommended maximum bulk and film temperatures for Therminol VP-1 are based on industry ...
