PEX-A tubing is produced using Peroxide method.
Maillefer uses with an oven, infrared waves to bring the heat to the pipe. Compared to ram extrusion systems, the infrared technology offers higher productivity and product flexibility.
The advantage is a full, ready-to-use product at the end of the production line.

Thanks to the use of a powerful vertical infrared oven, the PXL-I line allows the continuous production of a full crosslinked pipe at speed up to 35 m/min.
