About us


Brookx Company B.V. (‘Brookx’) is a young company with a great history dating back to 1926. Brookx has been established October 1st 2003 via a Management Buy Out of the Power Electronics business operations of Thales in the Netherlands.

Our history

The history of Brookx Company goes back to May 1st 1926 when the brothers Leo and Pieter Van Der Heem (VDH) started producing radios in the city of The Hague, The Netherlands. VDH expanded its radio business to consumer electronics and professional equipment such as T&M equipment, mariphones, power supplies, traffic control and radar installations.

The consumer products were sold worldwide under the Erres brand while the professional equipment was branded VDH. The company prospered and in 1964 VDH was the largest industrial company in The Hague, employing over 3,000 people. In 1967 VDH was taken over by Philips and became part of the Philips Telecommunication Division, VDH concentrated on professional equipment. In 1979 VDH transferred to Philips Defense Division as part of Hollandse Signaalapparaten when VDH became Signaal Special Products (SSP). In 1990 Hollandse Signaalapparaten was taken over by Thomson-CSF and in 1994 SSP moved to Zoetermeer. In 2000 Thomson-CSF changed its name into Thales and SSP became Thales Special Products.

After a Management Buy Out on October 1st 2003, TSP’s Power Electronics business continued as Brookx Company. Several legacy power supplies, some dating back to 1979, are continued to be manufactured and serviced to date. At our premises a large bronze sculpture entitled “May your flight always be higher” created in 1951 symbolizes the drive and ambition of our predecessors. This stature was a gift from the VDH staff to Leo Van Der Heem at the 25th anniversary of the VDH company. Brookx Company keeps this spirit alive, today and in the future. With Brookx’ relocation to its founding city, the stature once more has a prominent spot in the new Brookx’ premises in The Hague.
