Industrial Refrigeration Service Visit

Tick Sheet for the Industrial Refrigeration Service Visit

The industrial refrigeration service visit is carried out inside a walk in room so some of the machine can be serviced in the dry. Good job because it is a bit of a rainy day- don't want to get the tick sheet wet!

Chiller Controller

The controller for the plant has been problematic from when the chiller was first lifted in. It faults out regularly: reoccurring known faults known to the customer. Part of the problem are low load conditions. This causes the chiller to go into various alerts then it eventually trips out

Over Complicated Program for the PLC

Another part of the problem are over complicated controls. I often think about the same machine in a critical process environment. This machine is bespoke so there will be a bog standard version as well. The controls on this version have too many sensors, generating too many faults. There is always something which trips it out when no fault as such is present. The controls themselves are a fault if they are problematic. Factory Managers don't like too many industrial refrigeration service visits because of spurious trip outs- they just want the plant to just run seamlessly. This customer, however, has to pay for more parts and more industrial refrigeration service is to keep it running

Trim the Ammonia Refrigerant

The chiller has a low refrigerant charge so an industrial refrigeration service visit has been arranged to trim the ammonia refrigerant. We have state of the art ammonia refrigerant recovery units Read More but these are used when handling tonnes of ammonia refrigerant. This is just a small 200kw industrial refrigeration plant so we will be using a smaller ammonia refrigerant recovery method

Oil Return During the Industrial Refrigeration Service Visit

Low refrigerant charge diagnosed during the industrial refrigeration service visit causing the oil to migrate to the low side of the system. The oil will need to be manually recovered from various vessels following the ammonia oil recovery procedure
