Carrier 30RBP

[Stretch79]

Afternoon all,

Have an issue with a Carrier air cooled package chiller.

The fault present is a Water Loop : Delta Pressure Error.

Have spoken to Carrier and have had no luck with them advising what the issue could be.

There are two chillers, both having the same issue as they're on the same chilled water circuit.

Has anyone here come across this, and if so can you give some advise please?

TIA

It is saying that the flow rate through the machine is not within the design envelope.

Hi Frank,

Yes in the o&m it states either high or low pressure, rest of the system appears to be ok, will be checking strainers to see if there is debris, maybe blocked the heat exchangers

The flow sensors or pressure sensors clean. I have seen them block up on Geo Clima chillers, once cleaned and reading right the are fine
