On the occasion of the Cannes 2021 Boat Show, Mase Generators are at the starting line of the new nautical season with a new stand with the total renewal of its coordinated image and with new products and new systems that place the brand among the privileged partners of the most important international shipbuilders. 

The company is continuing to develop a constant process of renewal of its range of generators and has started the development of new systems for the production and use of energy on board of pleasure yachts and commercial boats, both for the supply of electrical utilities, and for medium and high power hybrid propulsion systems from 50 to 500 kW with voltages over 800 volts dc in collaboration with various project system engineering companies. 

Two groups with Volvo Penta variable speed engines with a power of 180 and 500 kW respectively (VS 500 SV – VS 180 SV) will be exhibited in Cannes, underlining the exponential growth gained by Mase in recent years in the sector of special groups aimed at proposing increasingly compact, efficient and environmentally friendly solutions, in combination with certified engines equipped with active and passive SCR and FAP post treatment systems. 

Among the other novelties, it is worth mentioning a new version of the VS 15.5 which has been named LOW, as it is capable of delivering the same continuous power equal to 15 kW in single-phase output but with a fixed speed at 2300 rpm which guarantees a low level of noise and vibrations. 

Another innovative and interesting feature of this model will be the possibility of arranging the exhaust on both the right and left side, thus increasing the installation flexibility. 

Alongside the aforementioned model, another group will be presented to complete the VS range, the VS 12.8 Y which offers the Yanmar 3TNV74F, Stage V, 3-cylinder, 993 cc engine with 12 kW continuous power. 

As it is known, these variable speed generators make it possible to build more technological and more environmentally friendly boats because the engine revolutions vary according to the request of load; this results in lower consumption and noise, as well as greater comfort and the possibility of placing more generators on board, even distant, but always interconnected. 

Going down in power and moving on to the IS range (Intercooler System), finally, here is the brand new and super compact IS 4.05 i, where the i stands for inverter and represents the new technological development of our range. 

The unit is in fact equipped with a permanent magnet alternator combined, internally, with a conversion inverter that allows to considerably increase the efficiency (+ approx 14%) compared to the IS 4.04, an extremely interesting result, especially if consider that it is obtained at just 3000 rpm, instead of the 3600 rpm of the 4.04 version at 60 HZ, with a consequent reduction in noise and vibrations, but above all in consumption and emissions. 

That’s why we use the new Yanmar L70 single-cylinder engines, which meet the strictest European and American regulations regarding emissions. 

As per the tradition of the IS range, the case is completely closed and inside there is our water – air exchanger, which allows installation in any place, quickly and easily, without any exchange of air with the external environment. 

Our generator is mounted on two series of anti-vibration dampers, four connected to the fixing brackets and four close to the engine: a double set to avoid any type of vibration and noise. 

Last, but not least, we have made the most of the space, concentrating a lot of power in a very small footprint, with 3.5 kW continuous at 3000 rpm, for a weight of only 96 kilos which makes the machine easy to install. 

It has to be underlined the most innovative feature of the product, which being based on the inverter technology, offers a parallel operation device that allows you to synchronize two machines in a very simple and efficient way. 

This allows to install this type of gensets in multi-hull boats, multiplying the power, in a single supply line, greatly simplifying the on-board systems. 

Mase Generators is today more than ever focused on research and development of new products and technologies for the production of energy on board and for the propulsion of boats and this important challenge is really just at the beginning.
