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.

NORRES aeration systems expand the product range
The NORRES Group has expanded its range of aeration systems. In addition to polyurethane diffusers and membranes, the portfolio now also includes a diffuser and a membrane made from EDPM: PRO2AIR® EPDM 610 and PRO2AIR® EPDM 625.
PRO2AIR® EPDM 610 and PRO2AIR® EPDM 625 – The innovations
The NORRES Group has expanded its portfolio of aeration systems with new products and new materials. A membrane and a diffuser made from EPDM are now also available: the PRO2AIR® EPDM 610 membrane tube diffuser and the PRO2AIR® EPDM 625 membrane diffuser tube. The membrane has a wall thickness of 1.8 mm. PRO2AIR® EPDM 610 and PRO2AIR® EPDM 625 are used in industrial and municipal wastewater treatment plants as well as for pressure diffusion with fine bubbles, oxygen input for nitrification in activation basins and continuous or intermittent aeration. Other applications include oxygen input and circulation in fixed-bed and bioreactors, thorough mixing of activation basins, sand trap louvre aeration, renaturation of lakes and rivers, aquacultures and fish farming.
Both PRO2AIR® EPDM 610 and PRO2AIR® EPDM 625 are very user friendly – both products can be fitted quickly and easily. They provide very good resistance to industrial and municipal wastewater in accordance with the latest version of the DWA-M 115 Advisory Leaflet and also conform to RoHS guidelines. The very low pressure loss represents an important product benefit leading to optimal efficiency. PRO2AIR® EPDM 610 and PRO2AIR® EPDM 625 are designed for temperatures from 0°C to 85°C as well as for the following operating range: normal operation 6 to 8, minimum 2, maximum 12 and purge operation 15 Nm³/h (h*maer.)
