    How to test industrial equipment for noise levels?

    I have taken various readings at 7m and 11m of a particular genset but don't know if I should be using the A scale or C scale or something else. Is there a standard or "proper" way to measure the noise emitted from industrial machinery? Lets say you have a Radio Shack noise level meter and want...

    Boosting a 24V diesel (or natural gas) generator set from 12V truck

    dpc's comments are echoed by us. We think we can make Mike L's solution work. Many thanks to all that offered input.

    Boosting a 24V diesel (or natural gas) generator set from 12V truck

    Thanks for all the input, everyone -- much appreciated. After some more discussions with the client, it turns out that modifying their vehicles is a no-go. We have to modify/revise our gensets before they take delivery so they can jump-start them from a 12V vehicle. Gonna be ugly....

    Boosting a 24V diesel (or natural gas) generator set from 12V truck

    Hi dpc, thanks for the prompt reply. I've been asked to provide something that's "neat and unobtrusive" (my client's words). They lease the 12V trucks and vans (standard 1/2 ton and 3/4 tone domestic vehicles) and are hesitant to perform work like you suggested. I guess I was hoping for a...

    Boosting a 24V diesel (or natural gas) generator set from 12V truck

    It's not uncommon to see trucks boosting (jump-starting) 12V generator sets out in the field if they have trouble starting due to cold weather, etc. Any idea how this could be done if the generator set is 24V? I'm not interested in a scenario that would have me charging the genet's batteries...

    Back pressure question for fixed RPM engine

    We have a 125kWe natural gas generator set (having a 8.3L 1800 rpm turbocharged engine). The genset is housed in its oem enclosure w/internal silencer and has the vertically oriented tailpipe w/rain-cap just clearing the enclosure roof (nothing esoteric, just standard stuff). Anyway, our client...

    Cooling solution for enclosed stationary engine

    Thanks guys, judging from the replies I'm seeing here it's plain to see that my post was entirely lost in translation. This is likely my fault. Anyway, we have come up with a suitable solution is both simple and inexpensive. Cheers. P.S. Mike, yes the one-off alternator was built for us...

    Cooling solution for enclosed stationary engine

    Hi guys, thanks for offering to help. There is no manufacturer, per se. This entire piece (engine, alternator, enclosure, everything else) is a custom designed unit. The solution will have to come from me. It's simply airflow basics that I need help on. Picture a birds eye view of a 8' x 4'...

    Cooling solution for enclosed stationary engine

    I am trying to figure out a cooling solution for a stationary generator set that will be housed (relatively tightly) by a steel enclosure. The engine is ~8L in size, outputs about 150kW, and is fueled by an exotic gas which means it burns very very hot. My only concern is the engine block not...
