Electric Works for The Industry
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.
HARDO – the new Polish manufacturer of lighting fixtures and other electrical equipment for hazardous areas
A guest article. "All our products are ATEX and IECEx certified, What is essential, our products were designed based on direct input from installers who are the last link in the installation process in various facilities." - said Donat Czapski from HARDO.
Sprinkler system for transformers at power plants
We've designed in accordance with NFPA standards and installed a sprinkler system for oil transformers at a power plant.
Fire protection system for transformer
The objective was to build a fire detection and a sprinkler-based fire suppression system for oil transformers. The installation was designed to protect two 110 kV transformers.
