Heating System  Thermal air flow circulation from 4 sides preheat PCB quickly. Օ High setting value of A T between heating zones prevents interference between different zones.  Long preheating zones provide optimal heat to PCB. You can set lower temperature to reduce power consumption. Օ Modular heaters can be removed for easy maintenance. Rectifier board employed with 8mm Aluminum board results in effective heat preservation, sta-bility and exchange. Օ High-efficiency cooling chiller and long cooling zones can cool PCB quickly. (option)  Modularized cooling blocks can be removed easily for maintenance. Nitrogen System Օ N2 system restrains oxidation and improves soldering performance.  N2 can be recirculated back into process to reduce N2 cost Օ Chamber rectifier can keep N2 inside and save on the cost of N2 consumption. Conveyor System  Special aluminum alloy with superficial oxygenation ensures high strength and less distortion. Օ Width adjustment with precision screws provides stable conveyor and automatic adjustment.  Chain shield ensures that PCB will not be stopped or dropped from chain. Օ Central oil reservoir system lubricates the chain automatically through computer control, reducing maintenance time.  Dual track conveyor system / Central support system (options)
