Our repair service 

You have a problem or need information?!

Our trained, qualified staff are on hand to help and advise you. No matter whether you are looking for refrigeration, air-conditioning, ventilation or filter systems for mobile or stationary use.
Equally, we are happy to assist you in all other areas, such as special constructions, transport refrigeration systems or additional accessories.
Our experienced employees take time individually to provide you with optimum, expert advice.
Our team also approaches repairs and servicing in a workmanlike and professional manner.
Moreover, we have service vehicles operating throughout Germany that cater for your needs quickly and reliably. Our service engineers, who are well equipped with radio telephones and all the standard service materials, are there when you need them.

Our spare part sales service  

Our aim is to help you as a customer quickly and without any hitches in the shortest possible time. We can only do this by maintaining a warehouse that stocks a large variety of different spare parts.
The years of experience of our trained staff ensure that we are able to quickly seek out or procure exactly what you are looking for from our diversity of parts. After all, efficient, fast service for selling spare parts is becoming increasingly important, and not just for you. Our qualified, experienced employees constantly strive to have all the standard spare and wear parts in stock to save you having to endure expensive and long downtimes. Our expert staff aim to dispatch your order on the same day.
However, in the event that a spare part is not available in our well-equipped warehouse, we, as an agent of Konvekta, Mitsubishi, WAECO and Webasto, are able to fall back on our partners’ central warehouses, so that we can replenish the missing stock over night.

Our partners

At Hellwig & Lünenschloss, we work with well-known manufacturers of transport refrigeration, air-conditioning and vehicle heating systems, such as Mitsubishi, Konvekta, WAECO, Webasto, Truma or Eberspächer.
A key partner for us is also Westermann in Hamburg, whose safety ventilation systems and Clion product lines we exclusively market.
Besides selling, installing and servicing new systems, we also particularly focus on the procurement of replacement filters for all filter systems on the market.
An important and indispensable part of our business is also the regional representation of Konvekta, whose product we distribute and service nationwide.
In 2003 we were given the status of a Webasto service centre.
To meet our customers’ needs, we only work with reputable, reliable and future-oriented partners, as their product quality has convinced not just us, but also in particular our customers.
