Klüber Summit R 100

Article-No: 050040

In many plants, refrigerators and heat pumps are at the core of the production processes. Breakdown of these machines can incur substantial costs and/or significant loss of production.

By using suitable refrigeration oils such as those of the Klüber Summit R series, efficient and smooth operation of refrigerators can be attained and optimised. This helps to reduce oil consumption and the associated need for maintenance as well as to optimise downtime.

Klüber Summit R oils are fully synthetic high-performance lubricants especially developed for heavily loaded ammonia refrigerators and heat pumps.

The Klüber Summit R series is characterised especially by its high chemical and thermal stability attained with the carefully selected base oils on the basis of polyalphaolefins. Depending on the system design, Klüber Summit R products might also be successfully used with carbon dioxide (R744).

The Klüber Summit R series has a high viscosity index, good shear stability and excellent low-temperature flow behaviour, giving the products large reserve capacity compared with the mineral oils available on the market. Furthermore, the Klüber Summit R series is characterised by low solubility in R717 and R 744. This enables higher film thickness in the lubrication point, contributing to reliable, low-wear compressor operation. The Klüber Summit R series can be used at high operating temperatures and in refrigerators with very low evaporator temperatures.

The products' chemical stability and low vapour pressure give rise to reduced oil carryover and oil vapour content, leading to lower oil consumption with positive effects on refrigerator efficiency. The products have a lower friction coefficient than mineral oils, which likewise contributes to the system's efficiency. Klüber Summit R oils are successfully used e.g. in refrigerators and heat pumps made by GEA, Mayekawa and Howden.

Klüber Summit R oils are registered as NSF H1 and therefore comply with FDA 21 CFR § 178.3570. The lubricants were developed for incidental contact with products and packaging materials in the food-processing, cosmetics, pharmaceutical or animal feed industries. The use of Klüber Summit R oils can contribute to increased reliability of your production processes. We nevertheless recommend conducting an additional risk analysis, e.g. HACCP.

Benefits for your application

  • Lower maintenance costs due to long oil change intervals and reduced oil consumption because

    • the oil shows excellent thermal and chemical stability

    • the product's solubility in ammonia is low

    • separation of the oil/ NH3 mixture in the separator is very good

  • Higher refrigerator efficiency due to lower oil content in the refrigerant and very good flow characteristics at low temperatures

  • Lower operating costs due to long oil filter and oil separator lifetimes

  • Suitability for food-processing due to NSF H1 registration for use in food and pharmaceutical industries; compliant with FDA 21 CFR Sec 178.3570
