FRÄNKISCHE: alpex F50 PROFI® multilayer composite pipe system for more than 20 years

Safety and durability, easy installation and utmost hygiene: FRÄNKISCHE is a pioneer in the field of installation systems and has been on the market with its alpex multilayer composite pipe systems for heating and drinking water installations for more than 20 years.


Permanent temperature resistance, crimp jaw flexibility and lead-free design have been standard features for alpex F50 PROFI and alpex-duo XS for many years. Along with multilayer composite pipes in the dimensions from 16 to 32 mm, the systems also include a great variety of fittings – for maximal flexibility at the construction site.
