A Hamburg original since 1971<\/span><\/span><\/h1>
<\/div>

Hanseatic, practical, good.<\/p>\n<\/div><\/div>

<\/div>

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.<\/p>\n

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. <\/p>\n

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.<\/p>\n<\/div><\/div>

Overview<\/span><\/span><\/p>

How it all began<\/h2>\n<\/div><\/div>
<\/div><\/div><\/div><\/div><\/div>

From small-scale CO2 trading to a permanent fixture in the North<\/strong><\/p>\n<\/div><\/div>

<\/div>

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. <\/p>\n

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. <\/p>\n

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. <\/p>\n

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!”<\/p>\n<\/div><\/div>

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. <\/strong><\/p>\n<\/div><\/div>

Sven Stanke<\/span><\/h3>

“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.
