Delpro – Impingement Jet Dryer

  • High efficient evaporation of water and solvent at rates up to 600g/m width/min.
  • Air is impinged upon the web via a series of jets at variable air flows up to 30m sec.
  • The web is supported upon flotation boxes to minimise the use of path rolls.
  • Temperature of air is controllable up to 250°C, (subject to the heat source) designed for steam, thermal oil, electric or gas fired heaters.
  • Modular 2m lengths enables a fully adjustable profile through the drying tunnel and ensures an evenly dried, smooth coating, free from bubbles, pin holes or the effects of premature skinning.
  • Web temperature and humidity sensors provide feedback to ensure the optimum drying profile is achieved with minimum energy usage.
  • Exhaust air volume is controllable to dew point or solvent burden (LEL) for maximum efficiency and economic solvent recovery or incineration.
