What is a GasCube?
Minimum cost, pre-designed, single engine
power plant solution using:
W20V34SG (GasCube)
16V34SG option
Targeted for power plants wi th 13 engines
Features
High electrical efficiency throughminimization of plant own consumption
Simple technical solut ions
100% detail design
No changes in the cube, options outside(tanks, sw itchgear-room etc.)

GasCube highlights
Low own consumpt ion High electrical efficiency
low energy radiators with frequency control efficient ventilation concept
no air conditioning
Minimized footprint
radiators on the roof minimum space, maximumperformance
control panels inside the cube no control room
Cost effic iency & project execution
elimination of repetitive design
minimization of material excess streamlined no change order - project execution
containerized transportation
high level of pre fabrication
Integrated gas skid
exhaust gas module
