Faunsdale, AL | I would total up all the hp of all the motors, their amperage etc, VFD's if you will be using them on the generator (probably not?????) or Direct across the line start etc and get a quote from Cummins power systems, and CAT etc. That way you'll have a good idea of what you need.
Or you can just go with a minimum of 75 kW or better 100 if there's a lot of smaller motors that will run at the same time. I think the VFD is going to be the best route if you have a large enough single phase service to supply it all. If you have to pay for an upgrade etc, then maybe the generators come out ahead. I've always wanted to use LP or natural gas generator and run the heat from the radiator and exhaust into the bin or dryer so you don't waste the heat from the gas you pay for, but which doesn't get turned into electricity.
I know where there a couple of old Onan's and a Kohler in the 70-85kW range that have IH549 V8 engines. Could be pretty budgetary compared to new equipment. | |
