Howden maintenance schedules

Hiya all

Thought I should share with you the maintenance schedule of the Howden XRV and WRV compressors

in the beginning I thought the years or hours was just a scam to get more service on the compressors, since on ships in Norway running on RSW get maybe 2-3000 running hours a year.
But during the last 4 years as I have overhauled XRV compressors, i have noticed that if the compressor has been 2 years on a ship and only had 8-9000 hours it is possible to overhaul to factory new.
But if an XRV compressor has been on a ship for 4-5 years on a ship, with the same amount of running hours, it's a hit and a miss if the compressor is serviceable at all....

So my advise is, at least on shipborne applications to have your customer adhere to the years, not the running hours it makes the difference between buying a new compressor or having the one they have being serviced

Why do they want to change a shaft seal at interval shown?

Why do they want to change a shaft seal at interval shown?

I think, that howden has been in the market for so long that they know the average time of the components in their machinery... this is the recommended service times from howden, I have checked the alignment of compressors and motors where the shaft seals have been installed ten years before I even started working in refrigeration that are still working just fine.

The hours in these schemes are not absolutes, they are recommendations by howden

I would also not touch it if not leaking, could possibly leak after I did it & the day is all downhill from there.
