Hi all hope everyone is well
Got a problem with a Airedale chiller working as part of a close control system for a lab. The problem is with the hot gas bypass solenoid valve. Got called out to the unit yesterday. System had no charge. Found that the solenoid valve on the hot gas bypass had ruptured. What's funny is that the valve was a simple liquid line solenoid valve installed on a hot gas bypass. I always thought that a standard liquid line solenoid valve was no good for HGP. Anyway contacted Airedale who specified a replacement which I've got and fitted. Recharged the unit and system ran however the solenoid valve is very noisey almost like a hammer sort of sound. I've had to extend the bypass pipe as the new valve was too heavy to suspend on 1/4 inch pipe so extending to base of the unit. The hammer sound would make me think that the coil isn't powerful enough for the job. Although I have worked with solenoid valves in the past and know how they operate haven't studied HGP in any great detail. Can anyone explain why this hammer noise is happening as I've spoken to Airedale who assure me I've got the right valve
