EMD 2865kW

DESCRIPTION

One only: Electro-Motive Diesel Model 20-645F4BGA unit, rated 2865 kW for continuous service, 3150 kW for prime power service, 60 hertz, three phase, 4160 volt at 900 rpm.

This engine was manufactured in 1989, and was first put into service in 1990; mothballed in1996 and removed from the site in 1998.

Pricing is shown in the following chart in US Dollars.

This unit has been refreshed by a factory qualified staff of service technicians. Considering the apparent condition of this unit, it is our opinion that it could be put back into service without any additional service work being required. This machine was in operation / production when the facilities at which it was installed was shut down; there was no intent or apparent requirement to overhaul / refurbish the unit in the near future, had the facilities remained active.

This 645F series generator set has experienced approximately 6000 hours of service since it was refurbished at site . As the anticipated normal life expectancy between refurbishing is in the order of 30,000 hours, there is considerable useful life still available

Based on the current shop workload, shipment of the "F4B" units could be made within approximately three to four weeks.

Shown as adders to the basic genset price is a remote radiator package (subject to test and repair costs), heat exchanger and switchgear including electrically operated draw out circuit breaker and generator protection devices. The equipment is ideally suited for jacket coolant circuit heat recovery, if desirable.

All prices are exclusive of any Canadian or U.S., federal and provincial or State Sales Taxes, which would be extra if applicable.
