Reniso Ultracool 68 Is Used For Ammonia Refrigeration Plants With Deep Evaporation Temperatures Down To < -45 °c. Due To Its Thermal Stability, Reniso Ultracool 68 Avoids The Formation Of Oil Deposits And Sludge In The Compressor. According To This, Maintenance Costs Of The Refrigeration Plant (filter Replacement, Inspection Work Etc.) Can Be Considerably Reduced. Reniso Ultracool 68 Shows An Outstanding Low Evaporation Rate Which Is Significantly Lower Than That Of Conventional And That Of Hydro Treated Mineral Oils. In Practice, This Means That There Is Less Oil Loss In The Compressor (lower Oil Carry-over) Which Ends Up In Lower Oil Top-up Volumes. This Is Also An Important Point With Regard To Cost Savings In The Refrigeration Plant. Reniso Ultracool 68 Combines The Very Good Cold Flow And High Temperature Properties Of Synthetic Hydrocarbons With Good Elastomer Properties (good Compatibility With Cr Sealants) As They Are Only Known From Mineral Oil Products.reniso Ultracool 68 Is Nsf H2 Registered.viscosity Grade: Iso Vg 68...
