Optimal Sound reduction

The M-SQ Pro 25 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 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 25 is the 7 inch full colour touch screen control which will be connected with WhisperCare. This allows full control over the M-SQ Pro 25 generator system, 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 25 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 ever growing global network of distributors and dealers take care of technical support and service. Spare parts can be ordered from them or through shop.whisperpower.com.
