Slip Joint Engine Mounting


Patented mounting system utilizes a slip joint between the engine and skid– Relieves stress on the skid caused by thermal expansion– Greatly reduces the chances of skid failure– Minimizes the potential for downtime


Serviceability

Experience

Air Filters(condition-based maintenance)

Electronic condition-based air restriction sensorsreduce downtime– Provide advanced warning when

excessive air restriction is detectedin air filters

– Accurately determine when filtersneed to be changed

– Prevent unnecessary filter changesbased on hours alone

– Eliminate unplanned maintenanceand unnecessary downtime



Serviceability

Experience

Exhaust Port Temperature Sensors

Electronic exhaust port temperature sensors are fully integrated into the generator set control– Accurately record exhaust gas temperature at each of the

16 exhaust ports– Provide real-time indication of excessive exhaust gas

temperatures– Indicate that engine maintenance is required– Can be integrated into remote monitoring for trending

and alarm capabilities



Serviceability

Experience

Alternator Bearing and Winding RTDs Resistance temperature detectors (RDTs) in alternator bearing and

windings provide advance warning– Integrated into generator set control and displayed on HMI– Enable remote diagnostics– Allow operator to detect the potential onset of bearing failure– Provide the flexibility to schedule service when it is least disruptive

DC Load Management

Pre-Wired, factory-tested and validated common DC distribution box streamlines service and installation

– Single point of DC distribution– Allows for isolation of batteries of individual starters– Improves ability to safely service and trouble shoot– Enables breaker to be reset, rather than removing battery



Serviceability

Experience

Minimized AC Connections

Set-mounted AC distribution box accounts for all of the generator set’s single-phase AC accessories– Single point of connection to the

generator set’s powered accessories– Simplifies design and facilitates

installation– Improves ability to safely service

and troubleshoot– Contributes to clean/neat design

of generator set
