In 1994 TESSA was established with the task to provide support to industrial plants in Poland in the area of process and explosion safety and in developing their production technology. This provided foundations for the emergence of WOLFF GROUP which currently consists of two companies: TESSA and ATEX. The areas of their operation are complementary enabling us to offer comprehensive solutions to our customers.

ATEX Lighting – how to reduce costs

The cost of EX luminaires designed for hazardous areas is just one element that affects the overall costs of creating a lighting installation. In many cases, labor and materials costs for installation can account for up to several tens of percent of the final price. Therefore, by selecting the right ATEX luminaire tailored to the needs of a particular project, you can significantly reduce its total costs.
