IDEA #1OLBT8 ENERGY-SAVING EQUIPMENT FOR SPRAY APPLICATION (CDS-HVOF)

HVOF CDS DN COLD SPRAY ENERGY-SAVING EQUIPMENT FOR SPRAY APPLICATION (CDS-HVOF) We introduce the Equipment for Thermal Spraying Applications (CDS-HVOF), the new alternative for the thermal spray industry offering technical and economic advantages over current Detonation, HVOF and Cold Spray techniques.  Operates safely on a variety of fuels e.g., propane, propylene, natural gas.  Easy to select spray parameters, providing a wide range of coating properties.  Integrated software provides on-screen operator control.  Low thermal inputs to substrate during coating.  Sprays most commercially available powders.  Integrated safety features.  Modular system concept allows for easy integration in existing thermal spray cells.  Cumulative flame sprayer has weight -15 Kg.  Uses conventional powder feeders – up 5 kg/h.  Adjustable high frequency firing - 15…30 Hz.
