F-Register
Creating an F-gas balance
What an F-gas balance is, which data you need and how F-Register supports refrigerant records in kg and CO2-equivalent.
An F-gas balance shows where refrigerant comes from, where it goes and which stock remains available. For HVAC/R companies it is an important part of the administration around refrigerants, installations, cylinders and work orders.
In F-Register the balance is not treated as a separate spreadsheet. It is built from daily registration: cylinders, work orders, charging, recovery, disposal and stock corrections.
What should an F-gas balance contain?
A practical F-gas balance contains at least:
| Item | Explanation |
|---|---|
| Opening stock | Cylinder contents at the start of the selected period. |
| Purchase | New, recycled or reclaimed refrigerant added to stock. |
| Use | Refrigerant charged or topped up in installations. |
| Recovery | Refrigerant recovered from installations and registered in a cylinder. |
| Disposal | Waste or contaminated refrigerant sent for disposal. |
| Corrections | Weighing differences, returns or administrative corrections with a reason. |
| Closing stock | Calculated and registered stock at the end of the period. |
Kilograms and CO2-equivalent
The balance is usually maintained in kilograms. For F-gases, CO2-equivalent is also relevant and is calculated using the GWP value:
CO2-equivalent = refrigerant amount in kg × GWP / 1000
This shows both the amount of refrigerant moved administratively and the climate impact of the registered amount.
Why cylinder administration matters
Without current cylinder administration, errors quickly appear:
- a technician takes a cylinder and returns it later with a different content;
- refrigerant is temporarily recovered and later reused;
- a recovery cylinder contains old or contaminated refrigerant;
- a correction is made without a cause;
- purchase or disposal documents are missing.
F-Register therefore links cylinder transactions to users, work orders, installations, invoices and correction reasons.
How F-Register helps
F-Register supports F-gas balances by:
- tracking refrigerant cylinders by type, status, content and maximum fill weight;
- letting technicians take and return cylinders;
- registering charging, recovery, dismantling and disposal as transactions;
- calculating kg and CO2-equivalent per refrigerant;
- requiring explanations for cylinder deviations;
- linking purchase and disposal documents to cylinders;
- generating reports for audit and internal checks.
Practical tip
Work from the work order whenever possible. That way the balance is created from the actual work and the administration does not have to be repaired afterwards in separate spreadsheets.
