Social responsibility
NORRES Schlauchtechnik has a long history of responsible behaviour towards the society we live in. We frequently participate in activities that benefit charitable organisations. We are extremely keen to support projects that help the socially disadvantaged, especially when they involve children. We also make an active contribution towards environmental protection.
NORRES Schlauchtechnik makes regular donations to “Noah's Ark”, a charity that describes itself as “a children’s hospice in the region and for the region”. The Ark’s concept, which is the only one of its kind anywhere in Germany, defines two main functions: to offer a haven for incurably ill children and to act as a short-term care centre for youngsters with severe disabilities. The aim is to assist the families concerned by providing professional care and respite for children and teenagers in the Noah's Ark centre. NORRES traditionally makes a donation to this deserving cause at Christmas.
At NORRES, all people are equal. All our staff benefit from the same opportunities. Their ethnic origin, religion, social background, age, sex or disabilities are considered to be irrelevant. NORRES maintains close links with a centre for handicapped people. Disabled staff carry out their work directly on the NORRES site and are therefore fully integrated in the life of the company.
The sustainable use of natural resources is firmly entrenched in NORRRES Schlauchtechnik's daily work processes. The move to our new “Am Stadthafen” facility coincided with extensive investments in eco-friendly production and HVAC technologies. Efficient insulation, double glazing, centrally controlled air conditioning with water chillers and production utilising heat recovery mean optimal protection for the environment. Since taking possession of the new and completely refurbished plant at the port of Gelsenkirchen in 2009, NORRES has succeeded in reducing the consumption of water, electricity and heating fuel dramatically – despite an almost fourfold increase in floor space.

PRO₂AIR Pre-PUR® membrane tube diffusers made from polyurethane
For higher safety reserves and lower operating costs
For a stable and safe operation of a ventilation system in use, the best properties of the membrane tube diffusers material are decisive. With its PRO₂AIR product family, NORRES offers a very suitable solution for ventilation systems - With significant added value: an increased energy efficiency and reduced operating costs.
NORRES membrane tube diffusers: PRO₂AIR Pre-PUR® 601 and PRO₂AIR Pre-PUR® 602
In the field of aeration systems, NORRES offers applications for industrial and municipal use, membrane tube diffusers with industry leading product and material characteristics in its product range. The membrane tube diffusers made of Pre-PUR® offer, in addition to a fine-blown pressure aeration, the best material properties as opposed to the usual membrane materials such as EPDM or silicone. The membrane material exhibits very good resistance to municipal wastewater according to the latest version of the DWA-M 115 Advisory Leaflet. Thanks to the Pre-PUR® premium polyurethane, the PRO₂AIR Pre-PUR® 601 and PRO₂AIR Pre-PUR® 602 are characterised by high tensile strength and tear resistance, and is also remarkably durable and robust. NORRES PRO₂AIR Pre-PUR® membrane tube diffusers resist permanent kinking. The tube diffuser membrane of the innovative PRO₂AIR is absolutely free of softeners and therefore permanently elastic: there is no hardening or embrittlement of the membrane. PRO₂AIR Pre-PUR® the membrane tube diffuser made from premium polyurethane has an optimised slit perforation. NORRES membrane tube diffuser are perforated using a specially developed technique that assures optimal quality consistency. All tools and materials utilised were explicitly developed for, and tailored to, the PRO₂AIR Pre-PUR®. This guarantees a uniform bubble pattern and optimal oxygenation efficiency across the complete specific air flow range. It goes without saying that the PRO₂AIR Pre-PUR® membrane is permanently resistant to microbial attack and hydrolysis, and the minimal maintenance requirement is a further added bonus in regards to quality. Both PRO₂AIR Pre-PUR® membrane tube diffusers successfully combine low pressure loss with a very high oxygen transfer rate and transfer efficiency – yet another feature that helps keep energy requirements and operating costs to a minimum.
