All components of the heating equipment used have the national compulsory safety certification mark. Each group of electrothermal components is connected by a centralized beam flange, which is set independently. It has the characteristics of simple  structure, high mechanical strength, safety and reliability, easy replacement, long service life, etc. Electric heat pipe is made of high quality products at home and abroad, with thermal efficiency of nearly 99%. It runs quietly and cleanly, meets the requirements of environmental protection, and does not emit NOx (nitrogen oxides) to the atmosphere. PLC control system is used in operation, with no operation button, no indicator light, touch screen panel, Chinese and English display, man-machine dialogue, operation authorization, real-time information and automatic page turning. The circuit is designed with fuse to ensure that the electric harmonics are controlled and to effectively protect the safety of the power supply circuit.
