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
