Hanseatic, practical, good.
A Hamburg original since 1971
From our own production facility in Hamburg-Stellingen, we supply our beautiful metropolitan region and the whole of northern Germany with carbon dioxide, dry ice, technical gases, balloon gas and liquid nitrogen.
Whether trade, industry, gastronomy, science or the event sector: many of our customers have been with us for many years – because they know that we are not just about product and service quality, but also about working together. It’s not for nothing that we are valued for our personal support, short lines of communication and straightforward approach.
We work pragmatically, think along with you and find solutions for every need together. Because we believe that a good supply needs more than just pressure in a bottle – it needs reliability. And we’ve been providing this free of charge for over 50 years.
Overview
How it all began
From small-scale CO2 trading to a permanent fixture in the North
Our story begins on September 1, 1971, when Manfred Wonsak founds a carbonic acid bottling company. The company started with two employees and a vision: to supply the catering trade in the greater Hamburg area with carbon dioxide.
In 2006, his son Michael takes over the helm. With a pioneering digital spirit and vision, he opens up new business areas and leads the company into a new era. When his wife Martina joins him three years later, everything picks up speed again. With her as the driving force and good soul in the company, the next milestone follows: the company’s own dry ice production.
An important step that has ultimately made us the No. 1 in the north for the rental and sale of dry ice blasting machines and compressors. In 2020, our online store will go live, making our range available nationwide.
Yes, a lot has changed since the company was founded, but one thing always remains the same: there is no trace of boredom. No wonder, because Martina and Michael Wonsak’s motto is: “Run your business like a heavy metal band!”
People
Our team
We may not be a heavy metal band, but together we really rock every project. In the warehouse, on the phone or behind the wheel – always competent and at eye level.

Martina and Michael Wonsak
“We are the second generation to run the business. We have completely rebuilt and expanded the dry ice business.”

Michael Wonsak
“As Managing Director, I am responsible for both strategic planning and the operational management of day-to-day business operations.
Since 2023, we have had the SOL Group as a strong partner at our side.”

Mario Čurčić
“I like coming to Hamburg, there’s always a lot going on at Wonsak, but everyone keeps a cool head and is well organized.”

Martina Wonsak
“I’m responsible for almost everything, from day-to-day business and HR matters to social media and purchasing.”

Sebastian Kopiec
“New challenges every day – that’s what I find particularly exciting at Wonsak. We try to make everything possible.” In my role, I am responsible for overseeing all aspects of our business, from strategic planning to day-to-day operations.”

Marilisa Pick
“I am responsible for all finance and controlling processes – and always keep an eye on the big picture. Because all other areas can only work optimally if the figures are right. Here at Wonsak, the chemistry is just right – between the figures, the team, the customers and the overall strategy.”

Jenny Nikitin
“As an Office Manager, I am always in demand to solve problems quickly and I usually succeed. HR is a new challenge that I really enjoy.”

Marc-Andreas Christlieb
“As a project manager, I work with the management and am convinced that our customers benefit from our service and also from the wide-ranging expertise in all our business areas. As an engineer, I am also always responsible for the smooth technical process in production.”

Nicole Ulbricht
“I process the orders afterwards and write your invoices. No two days are the same and I have to react flexibly every day, but it’s fun in the team. I wouldn’t want to work from home.”

Paulo Freitas
“I am responsible for the production of dry ice and the dispatch of online orders. I enjoy the extremely good working atmosphere every day.”

Christian Vockeroth
“I enjoy working in a team with my colleagues, it feels like home here.”

David Hameter
“As warehouse manager, I make sure that the gas is running and that our colleagues have enough goods on the trolleys to supply customers. I plan the demand for carbon dioxide, technical gases, liquid nitrogen and balloon gas must also be available in sufficient quantities.”

Sven Stanke
“Both filling the gas cylinders and selling them to customers who come to us directly is always a challenge. Whether it’s 2 KG bottles for the water dispensers or 37.5 KG bottles of Co2 for events. Especially in the summer months, when the sun is shining and everyone needs dry ice for parties, there’s a lot going on here in our yard.
I particularly enjoy serving our customers who run wedding halls and celebrate the opening dance with dry ice.”

Michael Timmermann
“Oldie but Goldie. I’m about to retire, but I can still get involved at Wonsak. I deliver carbon dioxide or dry ice, pack dry ice parcels for the online store, fill CO2 bottles or, or, or.
There is always something to do.”

“I’ve only been at Wonsak for a few months, I’ve already worked in almost all areas and I’m not sure what I like best. Whether it’s liquid nitrogen, dry ice, carbon dioxide or technical gases, I’ve learned to deal with everything. In any case, it’s a very nice team and I feel comfortable here.”

Rick Salzmann
