This week, AIS successfully performed an emergency hydraulic lube oil service on a 2,500 gallon oil reservoir at a customer site. The customer was having a hydraulic pump replaced and found a large amount of metal shavings in the piping. The AIS team evacuated the oil from the reservoir into temporary tanks and purified the oil to remove the hard particulate contamination. We then performed a confined space entry and cleaned the interior of the tank. We found the flor of the tank littered with metal shavings as well as various foreign objects. After the cleaning we pumped the oil into the reservoir and filtered the oil down to a 16/14/11 ISO cleanliness code.
