AlpinJet has always put strong emphasis on teamwork. Our expert operators are the main driving force behind our company. It is their hands-on experience and commitment that have secured us a place in the competitive industrial cleaning business for over 14 years now and that have allowed us to continue to grow – both in terms of the number of completed projects and their industry-specific complexity. Mutual trust among our high-pressure operators is paramount in the dangerous work they conduct every day – each operator demonstrates a strong work ethic and excellent interpersonal skills. Our operators possess the necessary capabilities to take on every type of cleaning task – they are thoroughly prepared, properly trained, extremely skilled and fully committed to their jobs.
