An Exclusive Interview with Mr Cooper and Mr Hiroharu Senju, Director, Sinfonia Technology Co. Ltd., Japan was conducted during the Daimon Genset launch
A Partnership Rooted in Mutual Strengths
The collaboration between Cooper Corporation and Japan’s Sinfonia Technology began with shared intent and complementary capabilities.
Mr Cooper shared, “Sinfonia is a very reputed company in Japan, listed as a Prime Member of the Japanese stock exchange. They’re a large multinational with diverse operations. They approached us with an interest in developing gas engines together. They saw value in our engines, and we saw value in what they could offer. So we collaborated, developed a product, and sent it to Japan. It was approved there, and now we’re selling it in India.”
From Sinfonia’s side, the focus was on leveraging their technological strengths to support clean energy initiatives in India. Mr Hiroharu Senju explained that, “Sinfonia Technology is actively working on clean energy solutions in Japan, including the use of ammonia, hydrogen, and LNG (liquefied natural gas). These energy sources are being considered for gensets and other applications. With this in mind, we’re looking to collaborate with Cooper Corporation to expand into the Indian market.”
Bringing Complementary Engineering Expertise Together
At the heart of this collaboration is a well-balanced division of strengths—engines from Cooper and alternator expertise from Sinfonia.
Mr Senju elaborated, “Our core strength at Sinfonia lies in alternators, especially those used in generators. In a typical generator setup, you have an engine and an alternator—the engine drives the alternator, which produces electricity. Sinfonia has deep expertise in alternators, particularly for high-capacity generators, and we aim to bring this technology into the Indian market.”
Mr Cooper emphasized the importance of engine design from the ground up, he said, “Our engines, designed by Ricardo, have a clear advantage—these aren’t retrofitted engines. They are designed and built from the ground up as gas engines. In fact, this is the only LPG engine certified under the CPCB IV+ norms. No other company currently offers this.”
Designed by Intent: Efficiency at the Core
This collaboration stands out for creating a gas engine not as an afterthought, but as a fundamental design objective. Mr Cooper noted that, “When you design an engine specifically for gas or diesel, you integrate it into the core architecture of the engine. It’s not about converting or retrofitting—it’s designed by intent. That gives you optimal fuel efficiency, power, reliability, and durability.”
Compact, Powerful, and Built for the Future
One of the standout engineering features is the V-Twin engine design, which offers both form and function.
Mr Cooper explained, “This is a V-Twin engine, while most of the competition uses a three-cylinder setup. Our two-cylinder engine is more compact, lighter, and more efficient—almost like a high-performance motorcycle engine. It has fewer components, less weight, and requires less maintenance.”
Tested and Approved: From Japan to India
Early feedback from both Indian and Japanese markets has validated the genset’s potential.
Mr Cooper shared, “We’ve received very positive feedback from early adopters. One sample was sent to Japan, they liked it, and that’s what encouraged us to move forward. While the engine is ours, the other components—like the canopy and electrical systems—were developed jointly. Sinfonia contributed to those elements, including making the product compatible with both 50 Hz and 60 Hz frequencies. That’s another unique aspect—this genset works seamlessly on both.”
Mr Senju added further detail on Japan-specific customizations, he said, “In our collaboration with Cooper, we’re not just developing the Indian model—we’re also working on a version tailored for Japan, which involves unique challenges. For example, in Japan, unlike India, the grid voltage is 100 volts, and the frequency varies between 50 Hz and 60 Hz depending on the region. We need gensets that can switch frequencies depending on the location. So, we’re working with Cooper to ensure the genset runs on both 50 Hz and 60 Hz—a feature that’s not required in India but is critical in Japan.”
Meeting Tough Regulatory Norms
Japan’s strict certification requirements also shaped the development process.
Mr Senju shared, “We also face strict regulatory requirements in Japan—for example, our gensets must be capable of running continuously for 72 hours. We’re collaborating closely with Cooper to meet these requirements and successfully adapt the technology for our market.”
A Long-Term Vision for Clean Energy
While the LPG genset is the first offering from this partnership, both companies see it as just the beginning.
Mr Senju said, “Looking ahead, we see this LPG genset as just the first step in a long-term partnership. Over the next five to ten years, we plan to expand into cleaner fuels like natural gas, ammonia, and ultimately hydrogen. Our shared goal is to move towards zero-emission energy solutions. We’re very excited about this journey with Cooper Corporation and look forward to what we can achieve together.”
Mr Cooper echoed this ambition while touching on the distribution model, he added, “We’ve also partnered with HPCL to distribute the genset through their outlets.”
This collaborative venture between Cooper Corporation and Sinfonia Technology represents a unique fusion of Indian engine design and Japanese electrical and systems expertise—built for both local needs and global aspirations.
