START WITH THE DETAILS
A useful first look.
Tell us the kW or kVA rating, voltage, phase, fuel, hours, quantity and whether the unit is operating, stored or already removed. Include known faults and available maintenance or test records.
Photos of the complete unit, controller and readable nameplate help us understand what is included. Let us know about an enclosure, trailer or associated electrical equipment.
Do you consider a single generator or a whole fleet?
Both. Send an individual unit or an inventory with model, output, hours, condition and location. Each opportunity is reviewed before an offer is made.
Can I contact you about a non-running generator?
Yes. Describe any known issues and missing parts. Condition, demand and removal requirements determine whether we can make an offer.
What about removal and transportation?
Nation Demo arranges and pays for all purchase logistics. We can come to your location or arrange shipment, with payment by cash, certified funds or wire transfer. Share whether the generator is installed, enclosed, mounted on a trailer or already disconnected so we can plan the purchase and logistics with you.
