Optimal for exhaust gas extraction – high temperature hoses
Industrial environments using combustion engines are often operated indoors. The resulting exhaust gases must be extracted using exhaust gas extraction systems in order to ensure a safe and clean air transfer. This does not only depend on the correct selection of the fan or filter, but also the exhaust hose plays a critical role in these systems. An effective exhaust system is only as good as the exhaust hose!
Simply flexible – the entire range of exhaust hoses
Exhaust hoses are primarily used to route exhaust gases from vehicle engines and other equipment away from the operator. Exhaust hoses are used mainly in vehicle exhaust systems, overhead and underfloor exhaust systems as well as engine test stands in industrial workshops. In order to guarantee smooth and error-free use, the hoses must have certain properties, because reliability in-use and quality are important. This means that hot gases can be transported up to several hundred degree Celsius without damaging the hose material. A flexible hose shape is advantageous in order to withstand vibrations, impact and balancing effects from outside.
The NORRES portfolio of exhaust hoses serves many applications. For example, the PROTAPE® TPE 326 MEMORY is a highly flexible and compressible hose that has a flow-optimized outer protection profile which ensures the best delivery performance. That means: low pressure losses, reduced fan output and lower temperatures in the hose. Therefore: longer service life and lower operating costs are passed down to the customer and user.
Innovative and new: PROTAPE® TPE 325 WEAR STRIP is fabric-reinforced and has as a highly flexible and compressible hose with external abrasion protection via an external helix. Due to the outer special sliding surface, the hose maximizes floor space and has a prolonged service life and is easy to use. The patent pending bridge clamp CLAMP 210 BRIDGE CLAMP is the perfect complement to the PROTAPE® TPE 325 WEAR STRIP. The bridge clamp can be used for attaching externally corrugated spiral hoses and is easy to handle during operation.
NORRES clamping hoses are based on a patented design, which offers numerous product advantages, particularly in the case of heavy loads - especially for the range of exhaust hoses. The CP HiTex 483 is ideally suited for use in a temperature range from -60 °C to 900 °C, even up to 1100 °C for short periods of time. Hoses, such as the CP HYP 450 PROTECT, with an outer protection profile, help to avoid the risk of lacquer damage when used in car workshops. The highly flexible exhaust hose with an outer protection profile has a high vibration resistance. This increases the service life and reduces the risk of downtime. The CP ARAMID 461 PROTECT combines our best hose characteristics as a clamping profile hose, especially when subjected to high loads and can be used for flue gas temperatures of up to 300 °C. Its aramid wall corresponds to the fire protection class M1 according to UNE 23.727-90. The CP HiTex 481 has very good heat resistance and can be used up to 700 °C for short periods of time and is flame retardant according to DIN 4102-B1.
