Generator Maintenance

'A planned programme of generator maintenance is essential to ensure your power back-up is there when you need it'

Investment in a power generator is a sensible way to ensure that your business can continue to function in the event of a mains power failure. However, unless your generator is regularly maintained by a fully qualified engineer there is no certainty that it will function correctly when required. Generator components can fail, filters become blocked or fuel supplies compromised. Selecting a preventative maintenance cover plan to meet your specific needs is essential to your business continuity planning. Not only does it protect your capital investment but it also guarantees availability of a service engineer when things are going wrong and you need a quick response. You may also want powertecnique to remotely monitor your generator, providing 24/7 peace of mind that if something goes wrong we know about it before you do and have already begun to implement the plan to correct the problem.

Additional Services

Powertecnique offers a range of additional engineer services recommended to assist you in correctly maintaining your critical and back-up power equipment. For details of our Load Bank testing, fuel maintenance visits and similar services please read on .

Generator Load Bank Testing

You’ve made a significant investment in your power generating equipment in order to support your load requirements in the event of a mains failure or indeed to provide you with power without the dependency on a mains supply. It’s essential that you are certain that your equipment is ready to support your power requirements should it be required. Our Load Bank service tests the whole system under controlled conditions and at a time to suit you.

Why Do You Need to Load Bank Test?

Load Bank testing constitutes an essential element of your preventive maintenance plan and business continuity planning to ensure your standby generator performs in the way that you expect it to perform and your business can continue to operate as required. This test checks the generator engine’s ability to perform and provide the power you need. Typically generators run at levels lower than their rated capability. A Load Bank test provides an artificial load that brings the engine to an acceptable operating load. This test ensures that any potential problems are identified in advance and provides you with the peace of mind that your generator will function correctly when required.

How Often Should You Load Bank Test

Over time generator sets that run on a light load can develop wet-stacking and carbon build-up in the combustion chambers and exhaust system. This can lead to increased oil and fuel consumption and poor engine performance. The use of a load bank helps prevent this and determines the generator’s capability to produce maximum output.

Regular testing reduces your risk profile and should be part of your business continuity planning. As a minimum we would recommend that you Load Bank test your generator annually as this will not only give you complete peace of mind but will also improve the generators performance and extend its serviceable life – protecting both your capital investment and your on-going business continuity. This can be part of your Service and Maintenance cover plan or arranged as a separate agreement.

Fuel Maintenance Servicing

Diesel engine fuel, when stored for extended periods of time is susceptible to natural deterioration causing contamination with foreign bodies including water, dirt and bacterial growth. When combined with oxidized fuel particles sludge is formed, causing filter blockages which can lead to your generator failing to start during a power interruption, or running intermittently risking catastrophic consequences. Powertecnique's Fuel Maintenance Servicing is intended to protect the integrity of your fuel supply to ensure that your generator's fuel system is not compromised resulting in generator failure and loss of power. It's a small investment to make to ensure your generator provides the performance you expect. This can be part of your Service and Maintenance cover plan or arranged as a separate agreement.

Why Do You Need Fuel System Maintenance?

Given the price of fuel, replacing contaminated fuel is now more expensive than ever. Powertecnique can now offer a clean and economic solution where diesel can be ‘polished’ on site and returned to the fuel tank. Our maintenance service reduces water, sludge and other contaminants to acceptable levels, eliminating the expense of totally removing or replacing the fuel. If power is critical to your business then generator fuel system maintenance is essential. Powertecnique’s Fuel System Maintenance service gives you peace of mind that your business is never at risk.

How Often Should You Maintain Your Fuel System?

Our recommendation is that your fuel system is maintained annually. This can be part of your Service and Maintenance cover plan or arranged as a separate agreement. Contact us today to understand more about how this service can protect your business operations.
