20 Years of ISAN


This year the ISAN brand celebrates 20 years on the market. During this time, it has developed into a major player in the domestic and foreign markets specializing in the production of heating units.

Let us take a step back in history, to the very origins of this enterprise. The year 1953 saw the founding of Univa, a company that combined glass and textile production. Over time, its portfolio was expanded to include the manufacture of furniture and radiators. In 2003, AMTEX bought the remnants of Univa, transforming it into a modern factory under AMTEX Radiátory s.r.o. Subsequently, the company acquired Opltherm s.r.o. and expanded its product range to include trench heaters. In 2003, the ISAN brand was also established, under which the heaters were marketed. It was not until 2006 that Amtex was renamed to today's ISAN Radiátory s.r.o. Much has happened in these 20 years. The company has expanded its operations beyond Europe to other countries around the world. It is investing in state-of-the-art technology and has expanded its production facilities to accommodate a greater number of orders. Furthermore, it is involved in the development of both the existing units and new product lines. All this has enabled the company to widen its customer base and to develop further. The ISAN logo itself has also evolved over these two decades. However, its color design has remained the same all this time, using a blue font on an orange background, as these two colors are very dominant and impossible to overlook. This year we decided to slightly modify the logo. We approached this task with respect and with the intention of maintaining the continuity of the brand.

ISAN's journey continues. We keep working on ourselves, constantly evolving, and improving our products, quality and services for our customers. We recognize that this is the only way we can continue to grow successfully in the future.

We would like to thank our business partners for their cooperation so far and look forward to continued success together.
