HMR Hydeq AS
Short and long term benefits
HMR Hydeq develops and builds a wide range of mobile and stationary equipment for the aluminum industry.
The production facility of HMR Hydeq is located very close to Hydro Aluminium Årdal, and therefore HMR Hydeq is able to benefit from close co-operation with potroom specialists, operators and R&D personnel. This allows us to develop the most suitable equipment for pot-handling that meets the needs of both today and tomorrow technologies. The plant, which operates both end-to-end and side-by-side prebaked pots, offers HMR a range of unique possibilities in adapting our vehicles to different types of technologies.
The business was established in 1989, as a subsidiary of Hydro Aluminium Årdal, one of the largest aluminum plants in Norway. HMR Hydeq is now a private company incorporated in HMR Group. In January 2013 HMR Hydeq AS merged with HMR Årdal AS and the new company continues under the name of HMR Hydeq AS.

Automated Stud Repair Lines
HMR has developed and operates a new revolutionary system to repair the anode yokes (called otherwise anode hangers or hexapodes) by replacing worn-out studs with the new anode pins whilst on the power and free conveyer in the rodding shop. The operation consists of cleaning, cutting and robotic welding of nipples. The system is completely automated and requires only one operator. The process is effective, safe and secure, and reduces downtime to a minimum. Please find more about this system here.
