Electrical System Design

We are involved in system and detail design down to cabinet level, as well as installation planning and set to work.

Power Electronics

Power electronic systems mainly for motor drives are designed upon customer specification.

Automation

We design and produce control systems for different applications, mostly for submarines and for the process industry.

Electronic Design

From single PCBs to entire systems. To minimize development time we use modern design and simulation tools.

Mechanical Design

Due to our experience from different defence projects we have developed a certain skill for packaging of electronics and equipment.

Maintenance and Repair

Mainly on our own products but also in general. Periodic maintenance is planned and conducted in cooperation with the customer.

Nöjdhs has been proudly supporting the Republic of Singapore Navy since 2005 in numerous overhauls.

In 2016 Nöjdhs was awarded Swedish Business of the year.

DC/AC Converters

DC/AC converters of the NEDA type has been delivered to navies around the globe since 1987.

Proximity switches

Inductive proximity switches for submerged operation has been developed and installed on submarines around the globe.

Process control

Process Control Systems has been delivered to companies mostly in the field of biogas processing.
