Our Heritage

The story of HITEC is one of innovation, ambition and sheer hard work. More than 123 years in power technology and more than 60 years in power protection. Highlights of over a century of rich history and innovative milestones from HITEC.

Founded by Mr. Hofstede Crull

1894

HITEC Power Protection can trace its roots back to 1894 when Hofstede Crull founded an electrical engineering consultancy company to design and build the first utility power station in the eastern portion of the Netherlands.

Hofstede Crull & Willink

1897

In 1897 Hofstede Crull partnered with mechanical pioneer William Willink to create Hofstede Crull & Willink, a design concern manufacturing electrical appliances.  

HEEMAF

1908

Several mergers in 1908 saw the creation of the Hengelosche Electrical Mechanical Equipment Factory, better known as HEEMAF.  Later, in the 1963, the company would become known as HOLEC.

Specialized in no-break power supply

1943

HEEMAF began to specialize in no-break power supply and braking systems.  The provision of these systems became increasingly important resulting in the formation of a project office and installation company.        

HEEMAF designed and built its first battery-based rotary UPS

1956

HEEMAF designed and built its first battery-based rotary uninterruptible power supply (UPS) system for a national telecom company.

First diesel rotary UPS system

1968

HOLEC designed and installed the first diesel rotary UPS system, a 300 kVA no-break system that was built for a data center application in northern Europe.

First Induction Coupling with free rotating inner rotor

1991

HOLEC designed and produced the Induction Coupling, a flywheel with a free rotating inner rotor. The revolutionary approach allowed for new increases in unit capacity.

World’s largest Dynamic UPS unit

2014

HITEC further innovated its Dynamic UPS systems to meet clients’ redundancy needs and operating voltage requirements. This culminated in the release of the industry’s first 22.8kV, 3600 kVA medium voltage Dynamic UPS.

Launch of the PowerPRO series

2015

HITEC listened to the changing needs of its clients and in 2015 launched the PowerPRO series, offering even higher efficiency, reduced downtime, and a more compact footprint in the first clad unit in the industry.

HITEC WINS AN IF DESIGN AWARD 2017

2017

HITEC Power Protection is a winner of this year’s iF Design Award, a world-renowned design prize. Every year, Germany’s oldest independent design organization, Hannover-based iF International Forum Design GmbH, organizes the iF Design Award.
