Refrigeration service software that holds up at audit.
Work orders, F-gas logbook with live balance per refrigerant, maintenance contracts, customer portal — built around EU F-Gas Regulation 517/2014 + 2024/573 from day one. Made for installers who get audited.
Honest country-coverage disclosure
Koldwerk was built first for the Dutch market. The product is EU F-Gas-compliant, but country-specific certifications vary:
- Netherlands (NL): Full support today — BRL 100, K25000, STEK certifications + Kiwa audit-trail out of the box.
- Germany (DE):EU F-Gas compliance works. ChemKlimaschutzV-specific reports + TÜV-format documentation on roadmap. Talk to us if you're an early adopter.
- Belgium (BE): EU F-Gas compliance works. FOD-specific certifications (e.g. BEKOO) on roadmap.
- Other EU countries: EU F-Gas baseline works. Country-specific audit formats are available on request.
We'd rather tell you upfront than oversell. If your country isn't fully supported yet, we can adapt the report formats for your country.
