Industrial and Commercial Generator Repair, Service and Preventive Maintenance

Service is not just a department to us, it is the core of what we are and the very foundation of our company. Supplying our customers with their power needs and helping them to succeed in their business is truly the essence of what Genset Services stands for. Genset Services is a premier generator service provider committed to long term and successful partnerships with their customers.

Industrial and Commercial Generator Emergency Service 24/7/365
We offer 24-hour service with a fleet of fully stocked service vans. Should your generator system fail we have all the resources to bring you back on line quickly. You won’t be stuck with costly delays and leaving phone messages with an answering service. We believe in personal contact and talking to people, not machines.

Fully Trained Industrial Power Generator Experts
Our experienced technicians service all makes and models of Bi-Fuel, Diesel and Gaseous generator systems including: Generac, CAT, Cummins, Doosan, MTU, and Kohler.

Industrial Generator Maintenance
We offer customized Preventative Maintenance (PM) programs to our customers. Frequently, standby generator systems remain idle for long periods. Like any other equipment, industrial generator systems need to be periodically checked and undergo routine maintenance to ensure they are fully operational when needed. A power outage is not the time to discover your standby generator system isn’t operational.

Generator Fuel Filtering

Many generator systems use diesel engines as the prime mover. Stored diesel fuel is susceptible to many forms of contamination and if left untreated over time will degrade substantially. Generator fuel filtering is required to maintain stored diesel fuel, especially on standby generator systems that are idle for long periods with little use.

Genset Services offers their customers a “3-Step” Fuel Maintenance Program to prevent fuel storage issues.

Concept of Planned Maintenance

Planned maintenance can be defined as performing service, maintenance, inspections and testing on a generator set on a pre-determined schedule. Each maintenance program should include inspections for the status listed below:

• Calendar Cycle Schedule – Depending on manufacturer recommendations and applications, cycles can be divided into weekly, monthly, quarterly, semi-annual and annual requirements.
• Operating Inspections – Inspections to be performed on generator when operating. Critical operations can be monitored 100% of operating time. Non-critical operations can have basic checks performed as determined by application.
• Layup – Generator are placed in layup when no longer in active use. Basic outline of steps for generator layup.

A selected generator style (Portable, Skid and Weathertight Enclosure) will be featured to illustrate the basic creation of the inspection.

The final section introduces Generator Source as a provider for Service Contracts for all generator sets sold.

All planned maintenance charts define checks to be completed at a calendar interval. Coolant, lubricating oil and coolant levels can be at normal levels, but can be contaminated. When performing normal maintenance inspections look for the following:

• Air Restriction Indicator – Indicates when air restriction to intake is greater than manufacturer specifications. Red in color means change air filter (scheduled or not). Generally indictor located on air filter housing. Can be reset after filter change.
• Fuel Water Separator – This filter separates water from fuel contaminated with water. Water is routed to bottom bowl and can drain via valve. This can indicate main fuel source supply is contaminated.
• Water Indicating Paste – Used to test main fuel supply. Spread on tank level stick. Pink in color with no water. Turns red when fuel is contaminated with water. Generally water at the lower section of tank.
• Oil in Coolant – Oil floating on the coolant when cooling system is at ambient temperature. Can appear milky after engine operation. Engine lubricating oil leak into cooling system. Can be cylinder head gasket, defective engine block or cylinder head. Defect is where oil pressure is higher than coolant pressure.
• Coolant in Oil – Oil has milky color on dipstick. Coolant leak into engine lubricating oil. Can be cylinder head gasket, defective engine block or cylinder head. Defect is where coolant pressure is higher than oil pressure.

Calendar Cycle Schedule

All generator manufacturers publish maintenance schedules broken down by a calendar schedule. Standard Maintenance Schedule is illustrated in (Table 1):

Events

Emergency standby generator systems should have at least two maintenance events per year performed. Examples listed below:

• Load Bank Testing – Generator is placed under load for a period of time using an external load bank tester.
• Confidence Test – Generator is placed under load for a period of time using facility as a load.
• Fluid Analysis – Lubricating oil, coolant and fuel analysis performed by laboratory.

Always follow manufacturer’s guidelines when performing maintenance, inspections and testing.

Operating Inspections

The application the generator is used in defines the inspections that need to be performed while in operation. Each application requires development of a different inspection.
Always consult manufacturer’s guidelines when designing inspections to be performed when the generator is operating. Consider recent repairs and add into inspection criteria.

Layup

When an emergency generator is removed from service for a permeate period of time it is placed in the layup status. Some basic steps to place a generator in layup can include:

• Disconnect generator batteries.
• Drain fuel system and change fuel filters.
• Drain coolant and change coolant filters.
• Replace air filters.
• Insure all intake and exhaust ports are covered.
• Disconnect all generator supply connections.

If shipping the generator all DOT regulations must be followed. Industrial shrink wrapping is offered by many companies and offers long term storage options
