So now we grease the tang on new Trane CVHE/CVHF chillers?
yep...and special grease and procedures too...not my idea.
It's tube brushing season...44% done...only 9,249 tubes to go!
In the past we always installed a homemade oil cup and every year at winter maintenance we would refill it with OIL-22, never had any leaks at the first stage vane tang.
If you dont stand behind our troops, please feel free...........to stand in front of them.
If the tang operator has one plug, It gets oil 22. If the tang operator has 2 plugs (latest design) then it gets grease, But not any type of grease. Must be rheolube 734A which is a R123 compatible grease.
It's All Good!!!
