产品描述
美孚™冷冻机油SHC 200系列是全合成,性能优越的润滑油,专门设计用于制冷压缩机和热泵。他们是无蜡配方,合成聚α-烯烃(PAO)烃流体,具有优异的热/氧化降解。随着他们的天然高剪切粘度指数和低温流动性,他们能够执行在恶劣的服务条件,是超越了许多传统的矿物油的能力。它们的溶解度和常用制冷剂的相容性低,在压力下的制冷剂存在高膜厚。这有助于减少轴密封泄漏。它们的稳定性和低挥发性的特性降低了“光端剥离”,它可以发生与传统的矿物油。美孚冷冻机油SHC 200系列润滑油可以减少摩擦损失,提高机械的工作效率
美孚美孚SHC 200系列润滑油推荐用于制冷压缩机在很高的温度下操作的润滑,和非常低的蒸发温度系统。他们是合适的压缩机系统使用的制冷剂,如氨和二氧化碳。他们的混溶性低二氧化碳使螺杆压缩机的使用二氧化碳的一个合适的选择。他们是兼容与最常见的制冷剂,除了二氧化硫,并已特别成功的系统中使用氨作为制冷剂。美孚美孚SHC 200系列是完全混溶的大多数传统矿物冷冻油。任何矿物油的混合物可能会减损美孚合成产品的卓越性能属性。
应用
美孚美孚SHC 200系列是全合成润滑油,专门设计用于制冷压缩机和热泵。
应用考虑:虽然美孚美孚SHC 200系列与矿物油产品兼容,混合物会减弱其性能。系统应彻底冲洗干净,更换一个矿产品与美孚美孚SHC 200系列产品。在R22制冷剂的情况下,从制冷机组供应商指导必须设法确保压缩机运行的润滑油与制冷剂分离是合适的。
典型应用如下:
商业,工业,热泵应用和海洋制冷系统
商业,工业和住宅热泵应用
推荐用于往复式和旋转式压缩机设计
推荐使用下列制冷剂:氨和二氧化碳
Mobil Gargoyle Arctic SHC™ 200 Series
Refrigeration Oils
Product Description
The Mobil Gargoyle Arctic SHC™ 200 Series are fully synthetic, superior performance lubricants, specifically designed for use in refrigeration compressors and heat pumps. They are formulated from wax-free, synthesised hydrocarbon polyalphaolefin (PAO) fluids, which have outstanding resistance to thermal/oxidative degradation. With their naturally high shear stable viscosity indexes and low temperature fluidity, they are able to perform in severe service conditions that are beyond the capabilities of many conventional mineral oils. Their solubility and miscibility with commonly used refrigerants is low, resulting in higher film thickness in the presence of refrigerants under pressure. This can help to reduce shaft seal leakage. Their stability and low volatility characteristics reduces the "light end stripping" which can occur with conventional mineral oils. Mobil Gargoyle Arctic SHC 200 Series lubricants may help reduce frictional losses and improve machine operating efficiencies.
Mobil Gargoyle Arctic SHC 200 Series lubricants are recommended for the lubrication of refrigeration compressors operating at very high temperatures, and for systems with very low evaporator temperatures. They are suitable for compressor systems using refrigerants such as ammonia and carbon dioxide. Their low miscibility with carbon dioxide makes them a suitable choice for screw compressors using carbon dioxide. They are compatible with most common refrigerants, except sulphur dioxide, and have been particularly successful in systems using ammonia as the refrigerant. Mobil Gargoyle Arctic SHC 200 Series are fully miscible with most conventional mineral refrigeration oils. Any mixture with mineral oils may detract from the outstanding performance properties of the Mobil synthetic product.
Features and Benefits
The Mobil Gargoyle Arctic SHC brand of lubricants are recognised and appreciated for their innovation and outstanding performance.
Our work with equipment builders has helped confirm the results from our own laboratory tests showing the exceptional performance of the Mobil Gargoyle Arctic SHC 200 Series lubricants. Not least among the benefits shown in work with OEMs is the superb low temperature capability providing excellent fluidity at low temperatures, as well as the resistance to viscosity loss due to refrigerant absorption under pressure, along with providing excellent bearing film thickness and shaft sealing properties.
By its nature, the PAO base stock used in Mobil Gargoyle Arctic SHC 200 Series oils provides exceptional thermal/oxidative resistance critical for high temperature applications. The narrow molecular weight distribution of the PAO base stocks also minimizes volatility and can help to reduce oil carryover. Mobil Gargoyle Arctic SHC 200 Series oils offer the following features and potential benefits:

Application Considerations: While Mobil Gargoyle Arctic SHC 200 Series are compatible with mineral oil products, a mixture will detract from their performance. Systems should be thoroughly flushed and cleaned when replacing a mineral product with a Mobil Gargoyle Arctic SHC 200 Series product. In the case of R22 refrigerants, guidance from the supplier of the refrigeration unit must always be sought to ensure compressor operation is suitable for efficient separation of the oil and refrigerant.
