Integrel Next Generation
What is it? A very high output alternator that can replace traditional generators, plus hybrid propulsion options Who’s it for? Cruising yachts with power generation requirements above 5kw per day
Four years ago Integrel launched an intelligent system allied to an extra large 9kw beltdriven alternator that makes use of the spare capacity that’s intrinsic in marine diesel engine installations. It was overall winner of the 2018 DAME awards and is now fitted as standard on an increasing number of new yachts, including all Balance Catamarans, which no longer have an optional diesel generator. It also features on the options list for many yards. High-profile clients include Riley Whitelum and Elayna Carausu of Youtube channel Sailing La Vagabond.
LOCKDOWN DEVELOPMENT
During the Covid lockdowns, when the company’s engineers were unable to travel internationally to complete or advise on installations, Integrel invested heavily in product development, massively accelerating the launch of new equipment, resulting in three new Next Generation products that won this year’s DAME awards Machinery, Propulsion, Mechanical and Electrical category.
The Integrel Inline performs exactly the same task as the original big alternator. However, instead of being a belt-driven device, it has a thin 10kw, 48V ‘pancake’ alternator that slots between the engine and gearbox. This lengthens the drivetrain by only 20cm, and dispenses with the belt drive to significantly reduce routine maintenance. It’s suitable for engines from around 30hp-200hp.
The Integrel Plus is a powerful hybrid propulsion and charging solution, with an electric motor rated at 30kw continuous and 50kw peak output at the back of the diesel engine. This serves two functions – it can be used for propulsion over shorter distances and at lower speeds, such as when entering or leaving port. Alternatively it can be used as a massive alternator/generator to charge a 40kw battery bank when the diesel motor is running.
The final new item, the Integrel Ultra, has a Torque Boost function, for planing motoryachts that need a big burst of power for a few seconds to get on the plane, before throttling back to a comfortable cruising speed. Incorporating an electric motor with 100kw continuous (150kw peak) rating into the drivetrain allows that shortterm boost power to come from batteries, rather than internal combustion engines. The engines can therefore be up to 40% smaller, reducing weight and significantly improving efficiency at cruising speeds. At displacement speeds the electric motor can be used as a very high-output alternator to recharge the battery bank, thereby rendering a separate generator unnecessary.
Pricing has yet to be determined, but the starting price of the Integrel Inline is expected to be in the region of £20,000. integrelsolutions.com
