From professionals – to professionals. Our goal is to enhance and improve our portfolio to meet customer needs and market potential.

Over the years, Nortroll has established a very strong brand. Our three recognised product lines are listed to the right.

ComTroll Repeater

The ComTroll stand alone repeater is based on the same hardware as the ComTroll 155 RTU/ICU.

The repeater can be configured to route signals to specific address ranges  keeping the radio traffic to a minimum for maximum throughput.

Any Nortroll RTU can be configured as a combined repeater extending the radio coverage to outstations further out in the network.


We offer professional help in setting up a system that will help you reach your goals in a cost efficient way.
