the larger NG295 unit is powered by
a PSI 14. 6 L turbocharged V8 gas
engine rated 361 hp.
Each machine has an automatic
dual-fuel switch that allows the generator to operate on propane in the
event that gas flow from the wellhead is interrupted or unavailable, the
company said. Electricity is produced
by Leroy Somer alternators that are
directly connected to the engine.
“When you’re running off wellhead
gas there’s often not enough pressure to run the engine or the gas is
dirty,” Franks said. “To combat that, if
the pressure drops, the engine automatically switches over to propane so
there is always a fuel source supplying the engine.
“To clean the wellhead gas we have
a scrubber system that collects water
and particulate matter and sends
cleaner gas to the engine for more
uptime and longer service intervals.”
The scrubber is supplied by Van
Gas Technologies, a division of
Generator diagnostics are supported by PSI’s own MasterTrak telematics system that is designed to allow
fleet and service managers to remotely observe machine performance.
The telematics system is standard
on Doosan Portable Power’s natural
gas generators and satellite options
A control panel monitors and indicates whether the generator is operating on natural gas or propane as well
as other critical functions. Operators
can use it to scroll through fault codes
to diagnose problems and determine
if the issue is something that can be
repaired in the field.
Manufactured in Statesville, N.C.,
Doosan natural gas generators are
expected to be available to the North
American market in late fall, the company said.
The new L20 light tower has a
hydraulic and cable-operated vertical
mast designed to help illuminate oil and
gas exploration activities and drill rig
sites. It can also operate as a generator, providing power to run job site tools.
