I have one used Capstone Microturbines Model 330, 30KW, 400-480VAC, Year-2000, 50/60hz, Natural Gas Units.  Turns on and runs, but when we connected to a Forklift Propane Tank, they seemed like they were getting flooded, you could see gas fumes coming from the exhaust stack and the units would reset.  We're not sure what is causing this and you are buying as-is with free shipping anywhere in the lower 48 States.  Your welcome to come inspect the unit, located in Cocoa, FL.  Price is for one with Owner's Manual and free shipping to any of the lower 48 States.  

International buyers- We will ship Internationally and fully crate the machine, but the price is FOB any USA Sea or Airport, you will be responsible for all other charges.

The weight of the unit is approximately 1285 lbs.

Dimensions 60" Long x 42" Wide x 82" High
