About us
Ewald Gattlen AG is a family-run building technology company based in Visp in the Upper Valais and part of Gattlen Group AG. Since 1990, the company has implemented systems in the fields of heating, ventilation, air conditioning, solar/photovoltaics and electrical engineering, accompanying projects from the first concept through to ongoing operation. An in-house planning office with specialists from various disciplines develops cross-trade solutions, complemented by services in permitting, subsidy applications, GEAK (building energy certificates), fire protection, Minergie and radon measurement. Implementation includes heat pumps (ground probes and air-to-water), wood and pellet heating systems, comfort ventilation, air conditioning systems with free cooling, in-roof and roof-mounted PV systems, battery storage and building automation with KNX, Loxone or Feller WISER. A 24/7 customer service with on-call technicians, maintenance contracts, ventilation system cleaning, thermography by drone and load profile analyses ensure reliable operation. The references include residential construction, hotels, school buildings, senior residences and industrial and process buildings in the canton of Valais.
