Out with the old, in with the new

Pictures of a backup power systems replacement evolution at one of our clients.  The old generator was a Katolight 45FGH4, circa 1990.  The new generator is a Cummins Power GGHE-1503557 60 KW 3 phase.  Unfortunately, when the Katolight generator was moved from the previous studio location in 1998, it was never installed correctly.  The 500 gallon propane tank was undersized, the gas tubing was undersized, etc.  We fixed those items, but the damage was done.  After running too lean under load a few times, the head gasket blew and there is oil in the antifreeze and antifreeze in the oil.  It is a Ford straight six engine, and sure, we could rebuild it, but why bother.  This is a major group of stations in a very lucrative market, it makes much more sense to replace the entire unit.

In addition to the head gasket problem, the load on the generator has increased. Since the old generator was installed in 1998, two more stations have been added to this facility. That means another air studio, another production studio, more computers, servers, air conditioning etc. Thus, the new generator is rated for 60 KW.

After the GENSET is placed, connections for remote start, battery charger, block heater and AC power output are made. We were able to reuse the existing conduit and cable, thankfully the electricians used 3/0 AWG cable for the AC power connections to the transfer switch.

It appears that they have dropped the Onan name, but not the color, completely.
