Physical foaming
With environmentally neutral and cost-effective N2 and CO2 gases
Promix gas dosing stations for physical foaming have been specially designed and developed to meet the needs of foam extrusion. Promix gas metering technology is characterized by high dosing accuracy, reliability and amazingly simple operation.
CO2 and N2 gas dosing stations for physical foaming
Promix gas dosing stations meet all the requirements of a modern gas metering system for foam extrusion. These include high-precision mass flow control, process visualization by means of trend charts, operator-definable
operating limits, data acquisition, and synchronization of the dosing rate with the extruder output. Implementation in the extruder control system via fieldbus system is also possible.
