Winterized turbocompressor unit and method for winterizing the turbocompressor unit

Abstract

A winterized turbocompressor unit has a turbocompressor and an oil supply installation for supplying the turbocompressor with a lubricating oil, the lubricating oil being a low-temperature oil and the turbocompressor and the oil supply installation being set up to be operated with the low-temperature oil.

1 .- 9 . (canceled) 
   
   
       10 . A winterized turbocompressor unit, comprising:
 a turbocompressor; and   an oil supply installation that supplies the turbocompressor with a lubricating oil wherein the lubricating oil is a low-temperature oil and the turbocompressor and the oil supply installation are configured and arranged to operate with the low-temperature oil.   
   
   
       11 . The turbocompressor unit as claimed in  claim 10 , wherein the low-temperature oil is an oil according to ISO VG 46 and has a low pour point at −54° C. and operates as the lubricating oil down to −20° C. 
   
   
       12 . The turbocompressor unit as claimed in  claim 10 , wherein the low-temperature oil is an oil according to ISO VG 46 and has a low pour point below −54° C. and operates as the lubricating oil down to −30° C. 
   
   
       13 . A method of operating a turbocompressor unit with a low-temperature oil, comprising:
 providing a turbocompressor;   arranging an oil supply installation for supplying the turbocompressor with the low-temperature oil as a lubricating oil wherein the turbocompressor and the oil supply installation are configured and arranged to operate with the low-temperature oil.   
   
   
       14 . The method as claimed in  claim 13 , wherein the low-temperature oil is an oil according to ISO VG 46 and having a low pour point at −54° C. and operates as the lubricating oil down to −20° C. 
   
   
       15 . The method as claimed in  claim 13 , wherein the low-temperature oil is an oil according to ISO VG 46 and having a low pour point below −54° C. and operates as the lubricating oil down to −30° C. 
   
   
       16 . A method for winterizing a turbocompressor unit, comprising:
 providing a turbocompressor with an oil supply installation that supplies the turbocompressor with a lubricating oil; and   introducing a low-temperature oil into the oil supply installation as the lubricating oil.   
   
   
       17 . The method as claimed in  claim 16 , wherein the low-temperature oil is an oil according to ISO VG 46 and has a low pour point at −54° C. and operates as the lubricating oil down to −20° C. 
   
   
       18 . The method as claimed in  claim 16 , wherein the low-temperature oil is an oil according to ISO VG 46 and has a low pour point below −54° C. and operates as the lubricating oil ( 13 ) down to −30° C.
