About HITEC
Dynamic UPS since 1968
HITEC’s roots go back to 1894. As HOLEC, the company built the first diesel rotary UPS in 1968 – a 300 kVA no-break system for a data centre in northern Europe.
1991 brought the induction coupling with a free-rotating inner rotor, 2014 the world’s first 22.8 kV/3600 kVA medium-voltage DRUPS, and 2015 the PowerPRO series. HITEC is today a subsidiary of Japan’s Air Water Inc., with head office and factory in Almelo.
Technology
The PowerPRO principle
A PowerPRO combines UPS, kinetic energy storage and standby generator in one machine on a sectional base frame.
Generator and choke act as an active filter. The energy store – Kinetic Energy Module or Energy Transfer Module with flywheel – keeps the generator running during an outage while the diesel engine starts and takes over the load through a mechanical free-wheel clutch. HITEC states up to 97 % efficiency and 40–60 % less space than static UPS.
