Alternative Power and Machine Generators


APM has a vast selection of the most user friendly units on the market. From the most basic Ford alternator unit to the high output four nozzle permanent magnet turbines, APM can match a power head to your site from over 250 different model combinations.

All Pelton style generators come with a 3 year warranty, and include a spare Delrin composite runner. Water box construction is marine grade powder coated steel, with a 14 inch square base.

Changing nozzles is accomplished by removing four wing nuts and lifting off the generator head. This quick release style of access allows nozzles changes in 2-3 minutes.

Brownell Microhydro mainly sells the Permanent magnet versions, as they are the easiest maintained highest output units.
