Refrigerant registration & balance

Refrigerant administration in Excel never balances. There's always a 0.5 kg discrepancy somewhere — and that's the finding that gets flagged at a Kiwa audit.

Koldwerk calculates the live balance per refrigerant type. Cylinders, mutations, stock, installations in the field — all automatic. If the discrepancy is more than 0.01 kg (10 grams), you get an alert on the dashboard.

BRL 100 and STEK are Dutch national certification schemes — full support today is NL-only. See our honest country-coverage disclosure.

What it does

  • Cylinder register with serial number, refrigerant type, capacity, contents, location, status (full / partial / empty / returned).
  • Mutation types: purchase, added to installation, recovery, return to supplier, transfer, disposal.
  • Live balance per type: purchased / in stock / in installations / recovered / disposed / missing / expected / discrepancy — loss tracked separately from documented disposal.
  • GWP values + CO₂-eq calculation for F-gas annual reporting.
  • Directly linked to work orders: refrigerant added on a work order → mutation + cylinder update happen automatically.

Use cases

How installers use this module day to day

A balance that closes for every audit

A pre-check before Kiwa's visit: one glance at the dashboard tells you if a mutation is missing anywhere.

STEK annual reporting

At year-end: one export button, a CSV with every field required for the STEK participant platform.

Multi-installer cylinder stock

Cylinders are issued to installers (see the Issue & return module). The balance collects mutations from every van.

FAQ

Frequently asked questions

What if the balance doesn't close?

The dashboard shows a red banner with the exact shortfall/surplus per type. Click through to the mutation history to trace the cause.

Which refrigerant types are supported?

All common types: R32, R410A, R134a, R290, R744 (CO₂), R407C, R454B, R1234yf. You can add custom types.

Can historical mutations be edited?

No — append-only. A correction is made via a counter-mutation so the audit trail stays complete.
