高性能传热流体

壳牌导热油 S2 X 是一种优质导热油，适用于间接加热的封闭式传热系统。它基于精心挑选的高度精炼矿物油，因其能够在传热系统中提供卓越的性能而被选择，并且含有抗氧化剂以提供较长的使用寿命。

• 工业传热系统 用于化学和加工厂、纺织制造等使用的封闭传热系统，其中油在大气压下运行的泵送系统中循环，有或没有惰性气体层。

•  延长维护间隔 壳牌导热油 S2 X 基于精心挑选的高度精炼矿物油，可防止油裂解、氧化和稠化。这可以延长油的使用寿命，前提是确保有效的流体加热和良好的泵循环，从而使加热器表面上的薄膜温度不超过上述限制。
•  系统效率 低粘度可在较宽的温度范围内实现出色的流动性和传热性。壳牌导热油 S2 X 还具有低蒸气压，因此不易破裂。这最大限度地减少了挥发性分解产物的形成；这些需要通过膨胀室和冷凝水收集器进行回收
•  抗磨损保护 壳牌导热油 S2 X 不具有腐蚀性，且具有高溶解力，可通过将氧化产物保留在溶液中并保持热交换器内表面清洁来减少沉积物的形成。

根据 ISO 6743-12 Q 系列分类 符合 DIN 51522 要求

High Performance Heat transfer fluid

Shell Heat Transfer Oil S2 X is a premium quality heat transfer fluid for use in indirectly heated closed heat transfer systems. It is based on carefully selected highly refined mineral oils chosen for their ability to provide superior performance in heat transfer systems and contains an oxidation inhibitor to provide long service life.

Applications

• Industrial heat transfer systems For use in closed heat transfer systems used in chemical and process plant, textile manufacture etc. where the oil is circulated in a pumped system operating under atmospheric pressure with or without an inert gas blanket.

Shell Heat Transfer Oil S2 X can be used in high temperature continuous heat transfer equipment with the following application limits:  Max. film temperature 315°C Max. bulk temperature 290°C

Performance Features and Benefits

•  Extended maintenance intervals Shell Heat Transfer Oil S2 X is based on carefully selected highly refined mineral oils and resists oil cracking, oxidation and thickening. This provides extended oil life, provided efficient fluid heating and good pump circulation is ensured, such that film temperatures on the heater surface do not exceed the limits above.
•  System efficiency Low viscosity enables excellent fluidity and heat transfer over a wide temperature range. Shell Heat Transfer Oil S2 X also has a low vapor pressure so resists cracking. This minimizes the formation of volatile decomposition products; these would require recovery via expansion chamber and condensate collector
•  Wear protection Shell Heat Transfer Oil S2 X is non-corrosive and has high solvency – this reduces deposit formation by holding oxidation products in solution and keeping internal surfaces of heat exchangers clean.
