About Dolder Electronic
Dolder Electronic AG develops and produces electronic controllers for renewable energies and general measurement, control and regulation technology (MSR). The product range includes universal controllers (eNet1, WPC3-S-U, SORA-WZ), heat pump controllers, heating controllers, solar controllers as well as operating units and accessories such as PT1000 temperature sensors, solar sensors and volume measurement parts. The core competencies lie in hardware and software/firmware development, the procurement of hard-to-obtain components and the evaluation of replacement types for discontinued components. In addition, the company offers electronics development on a customer contract basis, a configuration service (control concept, function modules, parameterization, simulation, documentation) as well as repair and overhaul service for all controllers in its own range. Fields of application are HVAC, energy management, home and building technology, solar thermal, industrial and process automation as well as remote control and analysis with data loggers. The headquarters are located in Gisikon in the canton of Lucerne; according to the company, the controllers are developed and manufactured as Swissmade products. As of 31 December 2025, the company will merge with ZETA Engineering AG as part of a succession solution.
