產(chǎn)品描述

美孚美孚SHC 200系列潤滑油推薦用于制冷壓縮機(jī)在很高的溫度下操作的潤滑，和非常低的蒸發(fā)溫度系統(tǒng)。他們是合適的壓縮機(jī)系統(tǒng)使用的制冷劑，如氨和二氧化碳。他們的混溶性低二氧化碳使螺桿壓縮機(jī)的使用二氧化碳的一個(gè)合適的選擇。他們是兼容與最常見的制冷劑，除了二氧化硫，并已特別成功的系統(tǒng)中使用氨作為制冷劑。美孚美孚SHC 200系列是完全混溶的大多數(shù)傳統(tǒng)礦物冷凍油。任何礦物油的混合物可能會(huì)減損美孚合成產(chǎn)品的卓越性能屬性。

應(yīng)用
美孚美孚SHC 200系列是全合成潤滑油，專門設(shè)計(jì)用于制冷壓縮機(jī)和熱泵。
應(yīng)用考慮：雖然美孚美孚SHC 200系列與礦物油產(chǎn)品兼容，混合物會(huì)減弱其性能。系統(tǒng)應(yīng)徹底沖洗干凈，更換一個(gè)礦產(chǎn)品與美孚美孚SHC 200系列產(chǎn)品。在R22制冷劑的情況下，從制冷機(jī)組供應(yīng)商指導(dǎo)必須設(shè)法確保壓縮機(jī)運(yùn)行的潤滑油與制冷劑分離是合適的。
典型應(yīng)用如下：
商業(yè)，工業(yè)，熱泵應(yīng)用和海洋制冷系統(tǒng)
商業(yè)，工業(yè)和住宅熱泵應(yīng)用

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:

Applications

Mobil Gargoyle Arctic SHC 200 Series are fully synthetic lubricants specifically designed for use in refrigeration compressors and heat pumps.

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.

Typical applications are indicated below:

• Commercial, industrial, heat pump applications and marine refrigeration systems
• Commercial, industrial and residential heat pump applications
• Recommended for both reciprocating and rotary compressor designs
• Recommended for use with the following refrigerants: Ammonia and Carbon Dioxide
