Linde has released its PRESUS™ C liquid carbon dioxide pressure booster that will help plastic foam manufacturers and gas-assist injection molders (GAIM) improve efficiency and quality.
PRESUS C carbon dioxide pressure booster systems can supply high-mass-flow LCO2 at a constant high pressure to a variety of industrial processes. Applications include high-performance spot-cooling of hot spots in plastic injection molds, and the supply of bubble-free LCO2 to metering systems such as the DSD 500 for the physical foaming of polystyrene (PS) and low-density polyurethane (PUR). The PRESUS C system can also supply high-mass flow for precision surface cleaning with dry ice particles, such as with the CRYOCLEAN® Snow system, which can clean and polish molds and OEM parts without water or ozone-depleting solvents.
Designed for precision and long service-life, the PRESUS C carbon dioxide pressure booster system automatically adapts to process demands. During pauses in production, the LCO2 mass flow will automatically stop to conserve cryogen and reduce energy consumption. Pneumatic operation and a dual-pump design enhance reliability and flexibility. During service or maintenance, the parallel pump can continue to supply LCO2 on a continuous basis to avoid interruptions in production.
Three compact models are available: the PRESUS C8 pressure booster can deliver LCO2 mass-flow rates from 10 to 220 lbs/h and operating pressures up to 1160 psi; the PRESUS C10 system can deliver the same mass-flow rates at pressures up to 1450 psi; and for heavy-duty industrial applications the PRESUS C50 system delivers LCO2 mass flow from 65 to 1100 lb/h at pressures up to 1015 psi. The compressor systems feature high-efficiency, low-noise operation, and are available with automatic switching and temperature conditioning options.
