Inpraise systems s.r.o.

Description

Inpraise systems is primarily focused on small-series production and prototyping of high-speed electric rotating machine systems and subsystems for special and demanding applications. Inpraise systems offers product development and engineering development services for energetics, automotive, HVAC, cryogenics, and space industries. The Inpraise systems’ bearing technology and the high-speed rotating machine technology heritage date to 1976. The Inpraise systems’ team combines an enduring passion for new space applications and abundant experience in this field. We work with young and experienced specialists who create unique technological competencies in the capital of South Moravia, Brno and in Vsetín. The company also closely cooperates with the Brno University of Technology (BUT). Inpraise systems is among the founding members of the Brno Space Cluster – the first cluster in the Czech Republic focused on commercial space activities.
