Product Description：
1. 4-sides Heating method, Temperature conduction by shelves, more efficiency.
2. With inflatable port, once-forming thermostability Silica gel Sealant strip, with good tightness
3. Double Observation glass window, inner is explosion - proof glass, outsite is resin protection plate, more safety.
4. Fastening handle, convenient for opening and closing.
