Linde Gases, a division of Tier One player The Linde Group, has launched its high-pressure metering technology for extrusion foaming using carbon dioxide (CO2).
The DSD 400 system is a specially CO2-adapted system equipped with a high-performance compressor, an accurate mass flow meter and a flexible control valve. Unlike standard membrane-based metering pumps, these features enable it to counterbalance fluctuating extruder pressures under intense climatic conditions.
Additionally, the DSD 400 doesn’t require liquid CO2 pre-cooling, resulting in easier and more reliable handling compared to conventional systems.
