Cost-effective and reliable marine and offshore controllers

DEIF's range of marine and offshore solutions helps you make the most of your engines, gensets, and other power equipment in any application. Maximize power, reduce fuel consumption, get longer service life – and get it when you need it with our efficient logistics, 24/7 global support, and extensive training options.


Short lead times and timely delivery

Our extensive manufacturing capacity allows us to meet any volume demand – regardless of geographical destination. We work hard to make sure our customers receive orders as quickly as possible, and we ship standard products in less than 7 days.

We manufacture all our products in-house at our Danish HQ in Skive to ensure we continue to meet demand and reduce customer lead times. So if you are struggling to get hold of control products through your usual supply channels, there has never been a better time to talk to DEIF.

Paralleling and protection

It is essential to synchronize genset breakers before connecting to a busbar already supplied by another power source. DEIF’s market-leading synchronizers are microprocessor-controlled, easy to install, and have no moving parts. The synchronizers are perfect for testing frequency, voltage, phase angle, and more.

Advanced paralleling and power management controller

Designed for applications in the marine and offshore industry, DEIF has an extensive range of control, protection, and supervision functions, applications range from generator control and protection to engineered power management solutions developed for diesel generators (including emergency diesel generators), shaft generators, shore connections, and bus tie breakers.

AMC 300 - Advanced Programmable Controller

The robust and flexible AMC 300 controller allows you to build resilient solutions for marine and offshore applications. Designed by marine engineers for marine engineers, the Linux-based PLC platform includes industry-proven technologies like EtherCAT and is easy to specify, install, and maintain.

Bridge instruments

DEIF offers a comprehensive range of Bridge instruments that conform to the relevant marine standards. A combination of standard and customised scale designs with advanced digital meters enable you build a solution for all kinds of vessels.

DM-4 marine - Integrated systems

The DM-4 Marine is also a perfect match for simple to advanced solutions for marine hybrid applications. These include battery solutions, variable speed solutions, and DC-bus solutions. Common to all, they can potentially reduce your fuel and maintenance costs. Reducing fuel consumption also means reduced harmful exhaust emissions.


What if we told you that installing the energy management system Blueflow would lower your fuel consumption instantly with a minimum of 10 % in case of proper use? Not as a result of slowing down but a consequence of your crew’s increased awareness!
