Automation for the marine sector Save energy and reduce emissions Danfoss pressure transmitters, temperature sensors, switches and valves international maritime certifications are your guarantee for safety at sea

By land and by sea, Danfoss engineering is contributing to a better and cleaner environment Maritime expertise Look around a modern ship, and you’ll find Danfoss hard at work reducing energy costs and emissions in the engine room and beyond. In fact, several Danfoss divisions bring a particular range of technical benefits to the marine sector. On their own, each division is at the forefront of its field, with industry-leading insight and innovation. Together, Danfoss’s many divisions provide a comprehensive array of products that keep major fleets running efficiently. Refrigeration, A/C and...

Small controls … Constant improvement of reliability and efficiency is not an option. It’s a prerequisite for success no matter what role you play in today’s increasingly competitive shipping industry. That’s why Danfoss continues to work on the details of the components that are small in size but big in impact. … that enable big gains Danfoss controls empower operators to sail smarter, faster and more efficiently. They monitor temperature and pressure in the places that matter most. And they put you in control of the processes that let you fine-tune performance. All approved for marine...

The benefits of intelligent control: Measureable improvements that you can rely on SMARTER SERVICE Preventive maintenance keeps engines running efficiently and eliminates costly downtime. That’s why a broad range of Danfoss controls make it easier than ever to base service procedures on real-time information for the parameters matter most for service. PREDICTABLY RELIABLE PERFORMANCE Trusting cooling and lubricating systems to work is one thing. Controlling them with sensors, mechanical switches and alarms is quite another. Danfoss components let crews lift performance reliability to...

If it matters, measure it. Danfoss helps operators monitor and control the performance parameters that matter most throughout the engine room and propulsion system. And we do it day in and day out in some of the most extreme environments on a modern ship. IMPROVED ENGINE EFFICIENCY Smoother combustion means better engine efficiency and lower fuel costs. Danfoss controls contribute to this ongoing effort all around the engine room, every day. REDUCED CO2 EMISSIONS As emission regulations continue to become more and more stringent, marine applications increasingly rely on advanced electronic...

Wherever performance matters, automation matters even more Danfoss adds automation throughout your ship – so you can start adding up savings in fuel, emissions and downtime.
