History of Ampulz

Ampulz dates back to the 1960s when a specialized engineering team at HOLEC decided to concentrate its efforts on improving power conversion technology. Ever since, we have been successfully applying our extensive knowledge and experience in numerous system-integration projects and technological developments worldwide.

Our flexible multi-site organizational structure and specialist know-how in all relevant disciplines provides asset owners, as well as technology partners, access to the very best in engineering and services.





On the basis of ‘building blocks’ – developed in-house – our systems can be configured according to the needs of any specific application.

The four core activities around which our company is internally structured enable us to offer you support with almost any technical query. The combination of activities is aimed at providing support throughout the entire lifecycle of your products and/or systems.

Whether your needs relate to product development, product assembly, system integration projects or service and maintenance, Ampulz is the partner par excellence that offers this support.
