Schultz s740 is a synthetic heat transfer fluid with excellent thermal stability for use in both gas and liquid states at high temperatures, and can be mixed together with similar products, such as the american dowtherm a and therminol vp-1.Excellent thermal stability: schultz s740 has excellent thermal resistance in heat transfer fluid, capable of reliable operation for long periods within a wide temperature range of 12400.Multiple choices: schultz s740 may serve as a heat transfer fluid in either liquid phase, or in gas phase where it evaporates and condenses. S740 is thus the best heat transfer fluid for heating systems in liquid phase at 12400, or in gas phase at 257400.Low vapor pressure: vapor pressure is crucial for heat transfer fluid used in gas phase. Schultz s740 has an extremely low vapor pressure at high temperatures, with a saturated vapor pressure of only 1.06mpa at 400.
