Details for sale 4 only 5.1 Plus or Minus mw portable Turbine - Gen. Sets - 60 Hz

 Here is the scoop on the units.

1. Technically there are 6 to 8 complete units.  – Original Voltage is 2,600 volts for all

2. 2 only of those units have been converted to 480 V via supply of a step down transformer.

3. Technically they all have been sold and the deal signed, but they are awaiting the funds.  So, the buyer has 15 days to come up with the cash or the units will be back on the street.  
   Actually, the prospective buyer has paid for two with an option to buy 6 more.

4. To set the other 6 units up with a step down transformed will take about 30 days.  Included in the $ 4.25 MM USD each price.

5. The units all have less than 4,000 hrs.  6 to 7 years old.

6. The units reside in Texas about 350 miles from Houston Port.

Gas Turbine Description

               4.1.1     General

The Model 501-KB7S one of the Siemens/Allison 501-K series of industrial gas turbine engines, which have been in production since the early 1960's.  To date, the 501-K series has in excess of 1600 engines in service with more than 30,000,000 operating hours.  Operating in continuous duty power generation are more than 680 engines with total operating time exceeding 15,000,000 hours.

               4.1.2     Classification

               The 501-KB7S gas turbine is a single shaft, simple cycle engine comprised of a high efficiency, 15-stage, axial flow compressor, directly coupled to a 4-stage, internally air cooled turbine sub-assembly operating at a speed of between 14,400 -14,600 RPM, depending on the exact application.  The compressor consists of a single stage boost compressor with a compression ratio of 1.5:1 which is directly coupled to a 14 stage core compressor with a compression ratio of 9:1 for a total compression ratio of about 13.5:1. The compressed air flows through a diffuser into the combustion liners where fuel is introduced. There are six combustion chambers of the full flow type assembled within a single annular chamber.  The engine incorporates modular construction including completely interchangeable accessory drive sub-assembly and turbine sub-assembly.  Each of these assemblies is manufactured to exacting standards with interchangeable parts so as to permit field replacement of sub-assemblies without re-balancing.  Each sub-assembly includes its own shafting and bearings.  Shafting is constructed with high precision splines to properly mate with adjacent shafting.  There are five high quality anti-friction main bearings which are pressure lubricated by an engine mounted pressure lube pump.  These bearings are designed to operate without pre-lube or post-lube and with minimum oil consumption and lowest possible heat rejection.
