SCHULTZ® S740
产品简介
Product Introduction
SCHULTZ® S740 是一种热稳定性极高的气/液两用高温合成型导热油,是美国Dowtherm A、Therminol VP-1的同类产品并可混合使用。
优异的热稳定性 ——SCHULTZ® S740在导热油中的耐热性极佳。可在12℃~400℃的宽温度范围内长期提供可靠操作。
高选择性——SCHULTZ® S740可以作为液相导热油使用,也可以利用其蒸发-冷凝的特性作为气相导热油使用,是您用于12℃~400℃液相加热系统或257℃~400℃气相加热系统导热油最佳的选择。
低蒸汽压——对于气相使用的导热油来说,蒸汽压性质相当重要。SCHULTZ® S740在其高温时的蒸汽压相当低,在400℃时饱和蒸汽压才达到1.06MPa。
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 12℃~400℃.
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 12℃~400℃, or in gas phase at 257℃~400℃.
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℃.
