VHP Series 2 GL To Series Four GSI Conversions
Stay ahead of falling emissions limits, reduce operating costs, increase power output, and improve engine availability with the VHP Series 2 GL to Series 4 GSI conversion kit.
With class-leading NOx, CO, and VOC emissions, upgraded engines can be sited almost anywhere in the world to add capacity to existing sites or as part of new construction. These upgrade packages align well with top-end and bottom-end overhauls, and can be combined with the reUp program for Waukesha* gas engines’ remanufactured parts.
BENEFITS
What can this upgrade do for you?
- Up to 38% higher gas flow and up to $290,000 in increased revenue annually1
- Up to 60% longer time between top-end overhauls and reduced oil consumption by up to 55%2
- Save up to $175,000 over the course of two bottom end overhaul intervals (96,000 hours) with reduced lifecycle costs, including up to 60% increased overhaul extension and reduced oil consumption
- Up to 90% lowered emissions without lowered performance—site up to 80% more horsepower with a GSI to GL conversion3
- ESM engine system manager with emPact control solution maintains emissions in specified range with little to no operator intervention, using only 3% of the tuning time of other systems4
- Wider fuel tolerance (13% lower WKI w/o derate) and faster response to fuel swings preventing detonation or misfire-inducing shutdowns
- Wider full torque turndown range available: 750 rpm minimum for L7044GSI vs. 1000 rpm minimum for L7042GL
- Improved altitude performance with no derate up to 8,000 feet at 100oF.
1 Assumes $0.25/mmBtu fee, 12 mmscfd for L7044GSI, and that hp scales with flow.
2 Assumes conversion from Series 2 to L7042GSI S4 or L7042GL to L7042GSI S4.
3 Assumes 0.3g/bhp-hr CO and NOx emissions reduction from 1.5 to 0.15 g/bhp-hr at Title V limited sites.
4 Assumes 15 minute (if necessary) adjustment period for emPact vs. 8 hours for legacy AFR controls.
