AMETEK HDR Power Systems designs, develops, manufactures and certifies custom power controller solutions for the Nuclear industry. The combined experience of HDR, Robicon and Halmar electronics reaches hundreds of nuclear installations around the world. This experience originates from the acquisition of Halmar and Robicon Group (HRG) by AMETEK HDR Power Systems, who built many Hydrogen Recombiners/Degasser and Pressurizer Heater Controllers prior to the acquisition by HDR. HDR has since done numerous replacements of their installations. We have built replacements of HRG controllers as well as new installations with an HDR controller base. We have worked with many CANDU, Westinghouse and KHNP plants to supply controllers.

AMETEK HDR Power Systems has interacted with various key players in this industry and we draw on the experience of our sister company, Solidstate Controls (SCI). We can build anything from a basic power controller to a custom-designed floor standing pressurizer heater controller with various alarms and metering.
