Reconstruction of the plant after an explosion:

Things don’t always go smoothly, however, we have never left our partners in trouble. We have always worked TOGETHER to achieve the goal.

President of WOLFF GROUP
BARTOSZ WOLFF

See who has already took advantage of our services

Above, you can see our customers… big brands that need to be provided with highest quality solutions This does not mean, however, that we work exclusively for tycoons. Among our customers are both global companies and those operating locally.

Then it all began
In 1994, Dr. Andrzej Wolff, Ph.D., D.Sc. (Eng.), opened the Tessa Engineering Office in Krakow and these were the beginnings of today’s GRUPA WOLFF. From the outset, the company relied on engineering knowledge, which allowed it to gain the trust of still other customers. The best students of the Faculty of Chemistry of the Cracow University of Technology, where Dr. Wolff simultaneously served as a research worker, were encouraged by him to join the company. Some of them still work in the company.
We provide both individual machines and complete systems. Our own design office and service and installation department allow us to carry out the tasks ourselves.
A company is a body which is made up of people
People enter into interactions and thus generate hundreds of ideas. These ideas are implemented by us transformed into numerous events.

We share knowledge
to create a safer industry
Every year, under the HAZEX brand, we organize nearly 100 technical training events, as well as a conference on process and explosion safety in industry. Thus, every year, we share our experience with about 1000 people.
“Express Przemysłowy”
“Express Przemysłowy” is a magazine that is to inspire and stimulate activities and above all to demonstrate the Polish ingenuity (“A Pole Can”). And although the core of the magazine are topics related strictly to the industry, we do not only focus on that area. Why? Because “Express” is a magazine for people with inquisitive minds who are bored with conventional trade magazines.

Fire protection systems – offer

Fire protection systems – offer

Sprinkler
systems

They are an automatic fire extinguishing system that detects the onset of a fire, sends information to the control system, and automatically starts the selective water extinguishing process – only where there is a fire.

Fire protection systems – offer

Deluge
systems

They are equipped with open fire sprinklers and can be divided into several extinguishing zones. When a fire is detected, the appropriate valves for a given area are opened. Water is released throughout the protected area.

Fire protection systems – offer

Foam
systems

We use them especially for high fire risk facilities, such as: fuel tanks, solvents, and other flammable liquids; warehouses of plastics; flammable products and/or those creating explosive atmospheres.

Strobe light sirens EX ATEX

Fire detection
and signaling

We design and implement complete fire detection and signaling systems. Depending on the needs, we use one of the four available systems or a hybrid of two or three of them, optimizing the investment in terms of technical and cost aspects.

Fire protection systems – offer

Spark detection
and extinguishing

These systems are designed for installation on industrial installation channels. Their task is to prevent a potential ignition source in the form of a spark, cigarette butt, or heated particle from reaching the device.
