Meet the M-SQ Pro 15, designed to last a lifetime
Every M-SQ (Super Quiet) Pro 15 WhisperPower diesel generator is designed for non-stop, 1500 rpm operation under harsh circumstances. They are robust, silent, compact and extremely reliable. All M-SQ Pro 15 generators are made in the Netherlands and tested during a 2 hours running period in one of the most advanced generator production facilities in the world, before distributed on a world-wide base by dedicated, service orientated, distribution partners.
Only the best 4 cylinder engines are applied: long lasting, reliable, silent engines, complying with EPA Tier 4 (USA standard) and Stage V (European standard). The engine is water-cooled and kept on a constant temperature via a heat exchanger.

Optimal Sound reduction
The M-SQ Pro 15 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.

7" Touch screen and DeepSea control
Important feature of our new SQ Pro range is the 7 inch full colour touch screen control which will be connected with WhisperCare. This allows full control over the M-SQ Pro 15 generator system, on board of a ship or boat. A perfect solution for instant information and/or historic with attractive visualization.
Features DeepSea control
- Genset parallel functionality included (ask for more details)
- Provides secure and simple off site monitoring (optional)
- Enables fault conditions to be resolved quickly and provides instant system information to aid preventative maintenance
- Graphical displays showing, charts, meters, power display, graphs and engine status information
- Information is displayed clearly and in a universal format for all users
- Language by choice
Pure power, excellent service & adequate parts supply
All M-SQ Pro 15 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

24/7 Monitoring with WhisperCare
The M-SQ Pro 15 can be monitored 24/7 in real-time remotely via the optional WhisperCare Wi-Fi router package. This is based on a 4G/ 5G internet connection in combination with a WhisperTouch 7ʺ or 10” monitoring screen.
With WhisperCare, all important parameters can be read from a distance via a cell phone, tablet or computer. In addition, full Wi-Fi is now available for computers, TVs and other enabled devices. WhisperPower systems can also be connected to various digital switching systems and each integrates perfectly with Naviop, Yachtcontrol, Garmin, Trigentic, EmpirBus and others.
