Dosing unit for the plastics industry ecofoam®

expansion agent

LEWA ecofoam is a redundantly designed, completely leak-proof system that meters different blowing agents used for foaming in the manufacturing processes of various types of plastics, including PE or PUR foam. The ecofoam metering system operates with a flow rate of 0.05 kg/h to 250 kg/h and a discharge pressure between 50 bar and 500 bar. LEWA ecofoam® Foam plastics with precision and safety. When producing plastics, numerous manufacturers rely on the ecofoam system from LEWA for the precise and fast metering of blowing agents in the extruder. The metered flow of the blowing agent is regulated according to the extruder output. The system – which features an integrated flow measurement system and a control unit – is tested and available as a turnkey system with multiple output ratings. LEWA ecofoam relies on tried-and-tested LEWA diaphragm pump technology. This means that precise, reliable, and low-maintenance operation is guaranteed for the non-lubricating blowing agent, even at a high vapor pressure level.
