SERVICE
WHO WE ARE
Ein leidenschaftlicher Produktentwickler mit einem hohen Grad an Erfindergeist, das ist Reinhold Kalteis, Gründer der S.E. System Electronic GmbH. The infrared radiant heater success story began in 2009, when Reinhold Kalteis had the idea of developing infrared radiant heaters by chance. A business partner wanted to import radiant heaters from abroad to Germany and sell them there. However, these showed considerable deficiencies. Since his interest was already at that time the electric heaters and the associated effective heat source, it was quickly decided to produce its own high-quality product.
Now, with over 30 of their own products and after sixteen years, Robert and Christian Kalteis have taken over the management of the company. With their many years of experience in the development of high-quality products, they know what is important when it comes to heat, air and light.
