Condition Monitoring

We also provide an oil and fuel analysis service. From a sampling kit we are able to provide certified results within a few days and provide a report showing any contaminant levels with interpretation of the results. The analysis looks for the presence of several metals, fuel and water including: Copper, Iron, Chromium, Aluminium, Lead, Tin, Carbon, Sodium, Fuel and Water. This can help to identify coolant leaks, excessive cylinder lining wear, piston ring wear, bearing wear, fuel ingress and air filtration problems. Please contact us for pricing.

Load Bank Testing

We provide a Load Bank Testing service using a fleet of mobile load banks which can be deployed at any site and matched to the rated load of a generator for on-site testing. Please contact us for pricing.
