What is a GasCube?
Minimum cost, pre-designed, single engine power plant solution using:
– W20V34SG (GasCube)• 16V34SG option
• Targeted for power plants with 1…3 engines
• Features– High electrical efficiency through
minimization of plant own consumption– Simple technical solutions– 100% detail design– No changes in the cube, options outside
(tanks, switchgear-room etc.)

GasCube highlights
• Low own consumption – High electrical efficiency– low energy radiators with frequency control– efficient ventilation concept– no air conditioning
• Minimized footprint– radiators on the roof – minimum space, maximum
performance– control panels inside the cube – no control room
• Cost efficiency & 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
