Koeltechnicus Cat I · Work through your exam, one topic at a time.

The Koeltechnicus Cat I credential (also written Koeltechnicus Categorie I, F-gas Koeltechnicus Cat I or Technicien frigoriste Cat I) is the Belgian certification for refrigeration technicians who handle fluorinated greenhouse gases. It is aimed at practising refrigeration and air-conditioning technicians, and at installers and service engineers whose work involves refrigerant circuits, leak checks, recovery, and commissioning. In Belgium, certification bodies such as BCCA (Belgian Construction Certification Association) operate certification and attestation schemes and publish quality frameworks and training offerings, but the specific Koeltechnicus Cat I certification page could not be retrieved at the time of writing, so the exam's question count, duration, pass mark, fee, format, retake rules and validity period are not confirmed here. Candidates should therefore treat any figures they encounter elsewhere as unverified and check them directly with the certification body before booking. Topics on this exam: F-gas certification of refrigeration technicians (category I) and Refrigeration installation and maintenance practice. The Koeltechnicus Cat I study guide has 2 sections and about 739 words.

01

F-gas Certification for Refrigeration Technicians (Category I)

Category I technicians may work on any refrigeration system, including those with charges of 3 kg or more of F-gas, and may perform leak checks, recovery, installation, and maintenance. They must understand the environmental impact of fluorinated greenhouse gases (high GWP), legal obligations under the EU F-gas Regulation (or equivalent national rules), and the requirement for certification and company registration. GWP and CO2 equivalent : The CO2 equivalent is the charge in kg multiplied by the GWP of the refrigerant. For example, R-404A has a GWP of 3922 (AR4) or 3943 (AR5); a 5 kg charge equates to 19,610 kg CO2e (using AR4).

Refrigeration Installation and Maintenance Practice

Proper installation ensures efficiency, reliability, and compliance. Key steps include: selecting correct pipe sizes to minimize pressure drop, ensuring proper insulation (especially on suction lines to prevent condensation and capacity loss), and leak-free brazing with nitrogen purging to prevent oxidation. Evacuation to below 500 microns (with decay test) removes moisture and non-condensables. Charging must follow manufacturer specifications, using weighing scales for accuracy.
