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.
