Refrigeration equipment companies and refrigeration contracting

Starting business operations in the field of refrigeration

If your company is going to perform refrigeration work, you must apply to Tukes for approval, a refrigeration equipment company certificate, before you start. Tukes may grant the certificate if your company has employed an appointed responsible person and at least one fitter who have adequate certificates of qualification and the required tools.

Typical refrigeration work includes, for example, installation and servicing of air source heat pumps and water-to-air heat pumps as well as servicing vehicle air-conditioning equipment.

The appointed responsible person is responsible for ensuring that the operations comply with the environmental protection requirements and that the fitters meet the qualification requirements. If the appointed responsible person works as a fitter, he or she must also meet the qualification requirements for fitters.

Applying for a refrigeration equipment company certificate

Before submitting the notification of operation, make sure that all requirements for the operation, i.e. the appointed responsible person, fitter, certificates of qualification and tools, are met. Also, make sure that the applications of the appointed responsible person and personnel are attached to the notification of operation, where appropriate. Tukes will charge the full fee also if the application is refused.

However, the appointed responsible person's qualification or refrigeration equipment company certificate are not required in the following cases, the fitter's certificate of qualification is sufficient:

  • installation and servicing of refrigerated units of refrigerated trucks and trailers
  • installation and servicing of refrigeration, air conditioning and heat pump equipment of ships and vessels
  • installation and servicing of electrical switchgear
  • recovering solvents.

The processing time for the certificates of qualification and notifications of operation is about 30 days.
