Innovation leader in insulation for fittings

 GWK Kuhlmann’s insulations for fittings and insulation systems have been the market leader and well-known throughout Europe for over 30 years. We are an innovative family business and offer high-quality and EnEV-compliant insulation systems for heating valves and heat exchangers and for the engineering and construction of stations. We are not reliant on a particular insulating material, but instead process various materials at our factory in Salzkotten near Paderborn.

Merchandise

In terms of our merchandise, we rely on materials such as PUR (rigid polyurethane foam) and EPP (expanded polypropylene). With the ES-box, we cover a major part of the fittings on the market, in both the flange and threaded area. The universal and affordable EPP-box supplements the threaded area.

We offer various modular systems specifically for the engineering and construction of stations and plants.

 The PWT box rounds off our range of merchandise. With this system, we offer tailor-made insulation for brazed plate heat exchangers.

 OEM (original equipment manufacturer)

Alongside our merchandise, we are a major player within the OEM sector. We develop and produce custom-fit insulations for all components in the field of building service. From the very start, we will give you expert advice on material properties, regulations and thermodynamic behaviour during operation.

Everything under one roof

We are your reliable partner, from the development of the concept to series production. In addition to PUR and EPP, we have production lines for XPE (extruded polyethylene), as well as a deep-drawing division in which we process PS (polystyrene), PE (polyethylene) and other plastics. Our particular strength lies in our specialization in the requirements of the building service industry – great diversity, small batch sizes, low-cost tools. We can offer you the most suitable materials depending on the intended purpose. We are also particularly good at material combinations for very specialised applications. With our assembly lines and packaging lines we can carry out preparation and packaging in line with customers' requirements.

 Manufacturing service

The proportion of our manufacturing services is rapidly increasing and we are able to manufacture tailor-made insulations without tooling costs, specifically for small batches and custom-made items.

More than just a manufacturer

We are more than just a manufacturer – we are continuously researching and developing. In our specially developed measuring laboratory, we are able to measure the heat loss of uninsulated and insulated valves and determine potential savings. We are also able to test low-temperature insulation for diffusion density.

Visit us at our booth and see our wide range and unlimited possibilities for yourself. At the booth you will find an intuitive and unique measuring device to find out about actually occurring heat loss. We look forward to seeing you.
