Coars not in your area ?
We are paying £225/bot/mnth for all service time,travel and consumables.
Compressor is extra but a scroll compressor is an easy on farm service, but we need to replace one imminently which will be another £5k
That includes chemicals?

Price i quoted was main service, intermediate one is half that price.
So £375/ month ish.

What CFM ? Will it power 3 bots ?

How come such a short service interval ? Our a4s are roughly 30000 between services and the a5s are cheaper to service due to us having a silicone bladder as a milk pump which costs circa £200 a pop and they sometimes do
So 1 robot of 2 is serviced every month or so.

Think it`s 8.5cfm. We have a pair running 2 bots.
This is the their range. Looks like 8.5 to 47cfm. All well under £5k

Two would run ours, we have one 14 CFM coping at the moment, are you servicing it yourself or do they offer a service package ?
Have you got one of these already ?
Are you fitting it to an existing tank ?
Do you have a dryer/filter setup and are you on food grade oil ?

Gather that this is a one tank/ milk jar as buffer setup?
New or different truck driver? Shipping more milk than last year? Time starts when driver procedure button pushed, so if takes longer to empty tank or driver is slow to get pumping, time could be lost. Check the CRS indications log and check time from driver procedure start to milk too long in jar.
If that is not it then possible software update has come in and time has shortened or reset to default. I am not up to date on the software, don't know if its a fixed time or adjustable. Give your tech. a call, may be able to fix settings over the internet.

according to the service manual you should have 45 minutes before it dumps milk.it's dumping at 40 minutes.
Ive called the techs they say nothing can be done besides shortening tank wash or buffer vessel.
one tank milk jar as buffer

Anyone have experience of providing air for lely robots using a piston compressor instead of either a scroll or screw compressor ?
They make a racket. They can’t be left running for as long, so need to be specced much bigger to cope with the down time.

A screw can run all day if need be, a piston needs to be off for a certain amount of time to cool down (Duty cycle), would need to check with the supplier.

It is do able though.

We are looking at a twin motor unit able to provide 50% more air than required with staggered start cycle and 600l of air storage.
With a cost of about 25% of comparable scroll unit and cheap as chips to service.
Life expectancy will be less but I have two renner compressors that haven't managed 20k hrs and one needs a new air end at circa £3.5k

Make sure it’s bolted down onto a rubber mat, and in a room that you can close the door to keep the noise in.

Maybe even buy 2 if they’re that reasonable, so you have a backup when it breaks down on a Sunday.

I think there is some sort of regulation about using food grade oil, the Renner would have been oil-free?
