The winter season has now come to an end and at this time we tend to experience a bittersweet sentiment at Colmis: a combination of fulfilment of seeing so many projects successfully completed at our proving ground, inevitably combined with the melancholic feeling of saying “see you next season!”.

It’s been an unusual year, yet within the difficult context around the world, we are glad to have been able to offer you a fully operative proving ground, following the guidelines set in our Covid-19 policy, and with most customers working onsite. And to those of you that couldn’t make it - mainly because of the international travel restrictions, we know how much you wanted to come and we missed you just as much, but we are already looking forward to welcoming you back very soon.

To all of you: A BIG THANK YOU for your support, year after year.

At our proving ground in Arjeplog we will now start to work on the preparations towards next season, but until then don’t forget we offer all-year-round engineering services through ColmisPlus (

Happy Spring on behalf of all the Colmis team!

Around this time of the year, we always encourage employees and customers alike to take a break from everyone’s busy schedule and get together to enjoy an outdoor lunch with simple but tasty local food. This tradition will sadly (but obviously) not take place this year due to the special current circumstances.

And whilst we are extremely happy to keep Colmis up and running and in full operation throughout this 2020/2021 season (with most of our customers onsite amid smaller teams due to travelling restrictions), we would like to take the opportunity to point out just how much we miss these kinds of social interactions with all of you; a small part of what makes Colmis special.

We will follow our Covid-19 policy at the proving ground as long as it takes, but are very much looking forward to the day when we can once again share a coffee break with you without having to think about keeping social distance.
