We have just completed a major project to install a 2mW set in the basement of a major new development in London.

As part of our role, we managed the final positioning of the set and 16500ltr bulk tank in the basement area. Our engineers then constructed the outlet attenuator, turning vanes and discharge plenum so that the cooling air was discharged at pavement level, keeping the noise below background level. The inlet cooling air was drawn into the generator room through an inlet attenuator.

Our engineers also manufactured and installed stainless steel exhaust pipework to the cradle mounted silencer, and from the silencer to the mating point, for the high rise twin wall stack. We installed the flow and return pipework from the tank to the set and installed a firevalve in the system, which was linked into the EPO system using a solenoid release system.

The fillpoint cabinet for the bulk tank was mounted at pavement level and the supply and vent pipes were run in thin wall stainless welded and flanged pressure tested pipework.

We then installed and tested all control and alarm wiring from the set to the panels and to the fillpoint cabinet. Finally all acceptance tests took place and the set was handed over to the client.

As we move into the New Year, our workload looks set to continue as strongly as in 2010, with fuel tank and fuel system upgrades for supermarkets and general commercial users in high demand.

We’re also working hard to find new and better solutions for the changing market and legislation.

Storing diesel externally in barrels without bunding and weather protection is now out of the question, so we’re investigating bulk storage in metal double skinned tanks that are directly connected to the generator via pressure tested pipework. To eliminate the risk of major fuel spillage, we always fit a solenoid at the tank so that fuel will only be allowed to flow when the generator is called to run.

We only use either high pressure double internally braided fuel hoses or welded stainless steel fuel pipes. Over time diesel will usually find a way to leak through screwed and socketed steel pipework, added to which corrosion on external pipework is always a problem, so our solution offers all sorts of benefits.
