Industrial Refrigeration Oil Service

An industrial refrigeration oil service visit was arranged because of an oil return issue. Several fans had been down on the air cooled chilled water system. This causes the chilled water system to unload so as to prevent a fault occurring. The lower mass flow rate of the refrigerant caused oil to migrate to the low side of the system. Several vessels are available with various forms oil return control. These vessels were valved off. A two man team with the correct ammonia PPE and breathing apparatus carried out the job

Not Enough Oil Recovered During Service to the Industrial Refrigeration Plant

Only some of the oil was recovered using during the industrial refrigeration service of the plant. Therefore, the engineers decided to add new oil to get the chilled water system running. The only problem with doing this is that once running the machine, the oil has to be got back out. Therefore, the industrial refrigeration oil service had to be carried out a second time to resolve the oil return issue

Industrial Refrigeration Service by Fitting Fan Decks

For this industrial refrigeration service visit, scaffolding had been erected in accordance with the Risk Assessment. The old fan decks were lifted out by the two man team. A really good team was sent out: one of the men was more technical and the other more mechanical- complementing each other with their different skill sets. The new fans were an updated version and the wiring was different. The fault link had to be adapted but the 0-10v input from the controller was the same. The controller reads the pressure from a transducer, then sends out a voltage which the fan turns into the corresponding speed

Service Testing of the Industrial Refrigeration System

The fault link had been correctly modified, so service testing of the industrial refrigeration system was carried out. The machine loaded up to 62% and monitoring continued during the rest of the visit
