Used generators offer cost savings without compromising quality!

Used generators become available for many reasons such as facility closures or system upgrades- these and many other instances cause used generators to be available to you at a dramatic cost savings.

In addition to cost savings, another key benefit is availability. Buying generators new can be costly and require several weeks of lead and delivery time. Critical Power Exchange’s inventory is constantly changing, but always available for immediate shipment.
