Lubricating oil Summit R series

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.
