We are KROENERT, COATEMA and DRYTEC. We are the companies of the ATH Group would like to introduce ourselves in more detail through our team. 

We are ATH. Pleased to meet you!

As the umbrella company of a group made up of tradition-steeped, somewhat more recently established but consistently innovative members, we attach great importance to a sense of togetherness. In the ATH Group we’re colleagues – not just people who happen to work for the same company! In order to give you more of an insight, we conducted brief interviews with some of our colleagues and asked them to describe themselves and their field of work in more detail. We also wanted to hear about their most interesting project, their favourite gadget and the app that changed their life.


“My most exciting project was nothing less than a prototype for the solar industry.”

“... Not only the system, but also the product itself were newly developed – they didn’t even exist before,” says Lutz Böwe (Sales) .
He’s married, father of a daughter and has been living in his adopted home of Hamburg for more than 10 years now. He has worked in sales for KROENERT since 1 January 2017.

The buzzwords digitalization and Industry 4.0 are on everyone’s lips, and they’re key issues at KROENERT, too. What was your first encounter with the digital age?
My first digital encounter was Windows 95 and the sound of the modem. Then there were the so-called LAN parties with long lengths of cable. Even back then, I was fascinated by the idea of “working” on something together as part of a network.

“Give someone a smile and you’ll get one back.”

My name is Melanie Rehberg, 29 years old. Although I’m not a native of Hamburg, I’ve always felt drawn to this beautiful Hanseatic city – because of work, friends, restaurants, concerts, musicals, the proximity to the North Sea and much more.

What did you do before you started working at KROENERT?
Unlike most people, I don’t come from an industrial background. In fact I trained as a hotel manager and gained a further six years of experience in the field before joining the ATH team on 1 July 2019. As a receptionist, I gained a foothold in the company and now I am happy to support the sales department as a sales assistant. 

What keeps you going on a day-to-day basis?
Give someone a smile and you’ll get one back. It’s this small gesture that keeps me motivated every day to sit at work with a smile and give my best.

“Why the production of prepregs was my most exciting project!” Interview with Markus Plocher, Head of Purchasing and Service Department

“Why was my most exciting project the production of prepregs – in other words reinforcing fibres (mostly fabrics) that are already pre-impregnated with resin and can be used in a whole range of areas, from aviation to the automotive industry? As the salesperson responsible, I was first able to sell the machine and then implement the mechanical design as the technical project manager. Today, I take care of the service for this machine with my team. In this way I got to know the entire cycle of a machine at KROENERT.”
