NEW | Akros UNI, Akros One


As of April 1, 2024, we are expanding our range of the popular Akros unit with hooks. The model is now available in 170 mm width and also in an all-electric version called Akros Uni. Moreover, we are also adding a stand-alone single-pipe model, Akros One, to the portfolio.
The Akros Uni is available in the same size configurations as the Akros with hooks. The unit's indisputable advantage is that its operation is independent of the heating system, ready to be used at any time.

The body of the Akros One unit consists of only a single pipe. It is available in both water and electric versions. Combining several Akros One units can add an intriguing design aspect to the interior.


The Popular Miro and Calypso Models with Center Connection


As of April 1, 2024, we are expanding our range of the popular Miro and Calypso heating units with new sizes and an optional center connection. 
Customers can now choose between a classic and center connection. This option facilitates customization of each unit to meet specific on-site requirements.
The units can also be ordered in different sizes. The Miro unit is currently available in eight variations instead of the original two. The Calypso unit also comes in a smaller size

                               Miro                                                         Calyspo

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.
