FeatureKoldwerkClimatools
BRL 100 / K25000 / STEK audit trail
Without an appeal-proof audit trail, any refrigeration installer fails their next Kiwa audit. Essential, not optional.
Present
Append-only audit log with hash-chaining + one-click BRL-100 ZIP export for Kiwa/InstallQ.
Present
BRL 100 / STEK / BRL 6000-25 reporting present; per-installation logbooks with audit-ready PDF export.
F-gas balance + GWP calculation
EU 517/2014 requires a closed balance per refrigerant type. Excel never hits zero — the auditor will ask why.
Present
Live kg + CO₂-eq balance per refrigerant type with GWP table from co2-eq.ts and annual reporting.
Present
Automatic ongoing refrigerant balance (purchases, use, emissions, recovery) — a core feature.
Machine-readable audit evidence (ZIP + SHA-256)
An auditor can verify and reuse a hashed, structured package — a PDF has to be trusted.
Present
BRL 100 audit package as a ZIP with manifest + SHA-256 hash; separate CSVs for installations, mutations and work orders.
Partial
Audit-ready PDF export confirmed; a machine-readable ZIP + SHA-256 manifest is not publicly confirmed.
Gas combustion + CO certification (BRL 6000-25)
Companies who also do gas/hybrid work want those inspections in the same system.
Partial
Installation records support gas + hybrid and CO personal certificates; CO certification is offered as a guidance track. A full Gas Appliances Act inspection flow in the UI is in development.
Present
Gas and hybrid logbooks + CO certification are a fully worked-out part of the offering.
LMRA for VCA installers
Last Minute Risk Analysis is mandatory for VCA-certified companies.
Present
Mobile LMRA flow with GPS, photo evidence, CRITICAL block, and installer + supervisor sign-off.
Unknown
Not explicitly found in the public offering.
Transparency + no lock-in
Your data and your progress should belong to you — not held behind a cancellation wall or a mandatory consultancy track.
Present
Public roadmap + release notes, and your full admin data always machine-readable and exportable.
Partial
Strong guidance, but the A-to-Z approach couples software and consultancy — less 'grab your data and go'.
Track record / installed base
A longer history gives a sense of security when choosing.
Partial
Koldwerk is a new product — we're upfront that we don't have a years-long installed base yet. Our proof is in software quality, not marketing numbers.
Present
Longer track record and a larger existing customer base.
Honest price + cancel monthly
No annual-contract lock-in. Our price is public (from €49/month) instead of 'request a quote'.
Present
€49/€69/€89 public on /en/prijzen. Cancel monthly.
Present
Public monthly prices at a comparable level, also cancel monthly — price is not a differentiator.

When Climatools is the better choice

  • You want a partner who runs the certification track for you (intake → action plan → audit guidance), not just software.
  • You do a lot of gas-combustion and hybrid installation work with CO certification (BRL 6000-25 / K25000) and want that flow ready-made.
  • A longer track record and larger installed base matter more to you than the newest approach.

When Koldwerk is the better choice

  • You want audit evidence a machine can read and verify: a BRL-100 ZIP with a SHA-256 manifest + STEK CSV, not just a PDF.
  • You want LMRA (Last Minute Risk Analysis) for your VCA installers in the same system — not as a separate tool.
  • You value radical transparency: a public roadmap, an open changelog, your data always exportable — no lock-in behind a consultancy track.
  • You want a modern, mobile-first system with offline mode and direct integrations (Exact, Debitan, Chamber of Commerce, Mollie).
