Unternehmenszertifizierung für die klimaschutzgerechte Installation, Wartung und Instandhaltung von Anlagen mit fluorierten Treibhausgasen beantragen

Does your company want to install, maintain, service, repair or decommission systems containing fluorinated greenhouse gases, check them for leaks or recover the gases? Then you need a company certificate.

You require a company certificate in accordance with the Chemicals Climate Protection Ordinance if your company installs, maintains, repairs or decommissions the following stationary systems:

• Refrigeration and air conditioning systems,
• heat pumps and
• fire protection systems.

Parts of your company that install, service or maintain stationary refrigeration systems within your company also require certification.

The reason for this is that the systems contain certain fluorinated greenhouse gases. Companies that operate such systems must prevent these climate-damaging gases from escaping, repair leaks as quickly as possible and regularly check the systems and applications for leaks.

You may only carry out these leak tests and maintenance and repair work if your company is certified. A certificate for the certification of the company will be issued to you upon application.

As a company, you must prove that you

• have sufficient qualified personnel. You must submit a certificate of competence in accordance with the Chemicals Climate Protection Ordinance.
• have the necessary technical equipment.

• Application form
• for all specified competent persons:
  • proof of reliability by submitting a certificate of good conduct of document type "O"
  • Certificates of competence for the personnel covering the activities in question (copies)

For the activities of installation, maintenance or servicing of systems

• you as a company must provide evidence of sufficient competent personnel.
• your personnel must have access to the tools and procedures required for the activities subject to certification.

For activities in connection with fire protection systems and fire extinguishers

• you as a company must have sufficient personnel with the appropriate certificate of competence available for the expected annual volume of activities and
• You must provide sufficient evidence of the type and number of technical equipment required.

If your company is registered as a so-called EMAS company in the Community Eco-Management and Audit Scheme, you can obtain the certificate under the following conditions:

• The environmental statement or the environmental audit report shows that you fulfill the above requirements
• and the following information is provided:
  • Name and registered office of the company,
  • Name of the site and the certified activities in relation to the site and its facilities,
  • Name of the authority (competent body), date and signature

Pursuant to point 21.6.2 of the Appendix to Paragraph 1(1) of the AllGO, the issue of a business certificate pursuant to Paragraph 6(2) incurs costs based on time, but at least €200.
