Norr Sprinkler handles sprinkler projects from design through installation to follow-up, plus service agreements and operator training, working from Luleå. Its site names its certification explicitly — SBSC certification under SBF 1020 as anläggarfirma vattensprinkler and SBF 1018 for its behörig ingenjör — and the SBSC register confirms company certificate 15-32 to SBF 1020:5, valid to the end of 2030.
