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
