Our Team

Klimer Štirn & Co. d.n.o. is a company with domestic capital, which has a registered office and calibration laboratory in Domžale. The company was founded in 2001 and started operating with 1 employee. Today, after almost 20 years, we have developed into a company with 15 permanent employees and some contract workers. The company has been successfully managed all these years by the director Sašo Štirn, who has more than 35 years’ work experiences in HVAC systems as well as in cleanroom testing.

The company's main activity is validation of cleanrooms. The main clients are pharmaceutical companies, medical institutions, pharmacies, and research institutes at home and abroad. With an intensive recruitment of highly professional technical staff in recent years, we have been increasing the production volume and the quality of our products. In 2011 we have got the international certificate for cleanroom testing by the Academy for Cleanroom testing ltd., Letchworth, UK and CTCB – Cleanroom Testing and Certification Bord to ISO 14644 . We are also the member of Irish Cleanroom Society, which enable us to follow the development of cleanroom testing.
