Good evening all,

Looking for some advice, Recently started a new job where I have to look after a site with 7 Climaveneta water chillers (in parallel)

Each Chiller has 4 Hitachi screws (40HP) and 2 evaporators.

According too guy servicing them before I started,
"2 compressors need gaskets replaced to repair leaks on chiller No. 3"

I dont have much experience on screws. I've just done a few service calls on them.

I'm presuming its the shaft seal that needs replacing(happened before I started), as the sparks on site has told me they've had leaks like this before.

The plant is 8 years old though. Are these compressors not supposed to be rebuilt every few years or so many hours.

It hasn't been happening here. What should i be lookin out for?
