AI Description
BetaCapabilities
This STULZ tunnel dryer is a modular, continuous-process system designed to remove moisture from plastic materials using hot water heating. Operating at a supply temperature of 120°C with return at 80°C, it processes 1,000 m³/h of air flow and integrates seamlessly into existing PLC control systems. The unit comes pre-configured for vacuum pump connections and links directly to upstream screw conveyors and downstream silo storage, making it a complete drying solution within a production line.
Industries & Uses
Manufacturers in injection molding, extrusion, and recycling rely on tunnel dryers to prepare plastic pellets and granules before processing. Proper moisture control is critical for product quality—wet material causes defects like brittleness and poor surface finish. This machine suits mid-to-large production facilities handling continuous volumes of thermoplastic materials.
What to Check When Buying
When evaluating this dryer, request comprehensive maintenance records and inspect the hot water heat exchanger for corrosion or scaling, as mineral buildup directly impacts heating efficiency. Check all instrumentation (temperature, pressure, and flow controllers) for calibration documentation. Verify the condition of internal conveyor belts and air circulation components, which experience regular wear. Confirm that all modular connections—to screw conveyors, silo battery, and rotary valves—align with your current equipment setup.
