Optimal Sound reduction

The M-SQ Pro 27 comes standard with a robust sound-shield with corrosion proof metal plating and heavy insulation material for optimal sound reduction. The sound shield is equipped with easy entry to all sides of the 27 kVA diesel generator and offers access to all maintenance related components from one-side.

Units can also be delivered without a sound-shield. Ask for our open units with or without sound-shield.

DDC with optional 7" Touch Panel

Important feature of the M-SQ Pro 27 is the 7 inch full colour touch screen control which will be connected with WhisperCare. This allows full control over the 27 kVA diesel generator on board of a ship or boat. A perfect solution for instant information and/or historic with attractive visualization.

Pure power, excellent service & adequate parts supply

All M-SQ Pro 27 generators are set up to automatically operate air-conditioning/ heating systems, heavy-duty tools, compressors, kitchen galleys, lights, refrigeration and cooling systems, computers and more. All at the same time, depending on the load.

The purchase of the 27 kVA diesel generator comes with a dedicated WhisperPowerWarranty Term. The standard warranty term is 2,000 hours of operation time. The ever growing global network of distributors and dealers take care of technical support and service. Spare parts can be ordered from them or through whisperpower.com.
