Sabroe Chill PAC reciprocating NH3 inlet valve failure

[Oz Fridgey]

I have been working on a Sabroe Chill PAC reciprocating compressor model SMC108L with water cooled condenser. running conditions are - 4 C evaporating / + 40 C condensing. Chilling 12.4% (by weight) ethylene glycol solution from + 2.5 C to - 0.5 C.

The machine has contant problems with the inlet valve failing. Has anyone else experienced this problem?

What was the cause and the solution to the problem?

Thanks
