Two molecular sieve tower, a molecular sieve tower to produce dry air, the tower's absorption plastic by the release of water. Another molecular sieve regeneration tower tower, two cycles of operation. Continuous drying. Dew point between -55 ° C and ~-60 ° C, drying product: 10KG/H ~1000KG/H, suitable for a variety of production needs. Especially suitable for PET sheet extrusion and the PET bottle production. Stability: Configuration Siemens brand electrical components, safe and reliable. The color PLC touch control panel, simple manipulation. Inch screen display, display the working temperature, the set point and any warning information. Flexibility: Professional engineering groups, senior program officer, at any time according to the production requirements change configuration. Accuracy: The temperature control module for high sensitive control processing temperature with automatic differential PID algorithm, ensure the high accuracy. Energy saving: Efficient recovery of waste heat, improve the utilization rate of heat energy. Intelligent management of raw material drying temperature: optimizing energy use, to prevent the materials thermal degradation or too dry.
