Devices that keep things moving

Keep your harbour and inland vessels sailing with our class-approved, cost-effective devices.



Workboats of every shape and size keep things moving in harbours and along inland waterways. From riverboats to lake freighters, from tugs and pushers to dredgers and fireboats, and from sampans to lighters and crew boats, they play a key role in waterborne transportation – and in the communities that depend on it. 

Operating in shallow waters close to shore, these craft rarely need the advanced systems required on oceangoing ships – but to operate safely and reliably, they need uninterrupted power and accurate control, and they increasingly need to reduce emissions and pollution. DEIF devices help owners and operators reach these targets and keep up the flow of people, goods, and services. 



Efficient control and a complete overview 

DEIF devices cover every control need on harbour and inland vessels. Our compact and cost-effective iE 150 Marine provides control and power management with up to two generators, two energy storage systems, two bus tie breakers, and a shore connection. You can monitor and control it remotely using an AGI 400 display, and you can get a complete overview from the bridge or pilothouse with our range of bridge instruments, including analogue and digital indicators and wind monitoring devices.

iE 150 Marine ideal for battery retrofit 

Replacing one or more diesel generators with an energy storage system is a quick way of converting workboats for compliance with tightening emission regulations. Easy to install and integrate with other devices, the iE 150 Marine helps you handle this retrofit operation quickly, reducing emissions and climate impact – and reducing fuel consumption.
