Generator Maintenance Checklist

Server Room Environments supplies and supports a wide range of generator and UPS installations protecting server rooms and datacentres.

Our project managers operate a nationwide generator service and maintenance team and provide a 24/7 emergency call out service, generator maintenance contracts and planned preventative maintenance visits.

Preventative maintenance visit schedules can be tailored to suit individual sites and generating sets. This is the general checklist our generator engineers work to.

Fuel Services and Condition Monitoring

Our generator team also provide fuel supply and condition monitoring services. The team can provide an oil and fuel analysis. Using a sampling kit our engineers can provide certified results within a few days and 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.

Load Bank Testing

As part of a generator commissioning or planned preventative maintenance visit our generator team can provide load bank testing from a fleet of mobile load banks.

Thermal Imaging

‘Hot spot’ analysis via thermal imaging is a service we use within server room and datacentre environments and external installations. Thermal imaging of the generator, UPS system and electrical circuitry, LV switchboards and panel distribution can identify overloads and the potential for electrical circuit breakdown.

To arrange a generator installation, maintenance inspection, load bank testing or thermal imaging survey please contact the projects team at Server Room Environments.
