The electric air heater is a heat exchange device that is converted into heat energy by use. It has the advantages of convenient energy supply, compact structure, temperature control, easy installation protection, and no pollution. The air heater structure is composed of a tubular container and an electric heating element, together with a temperature control cabinet (table). Some of the controls use leading digital circuits, integrated circuit triggers, and high back pressure thyristors to form an adjustable temperature measurement and constant temperature system to ensure the normal operation of the electric heater. The heating element adopts the straight tube type instead of the U-shaped structure, and the special sheet hand can be used for convenient installation and disassembly. The temperature control adopts thyristor adjustment and PID digital. Within the temperature control range, the required temperature can be set arbitrarily, and the constant temperature is automatically maintained, and the control temperature is ±5 degree . And there are over-limit sound and light alarm and multiple protection functions, which can be controlled locally or remotely.

1. Lè ki nesesè nan koule pwosesis la pwòp. Premyèman, opinyon sous lè a nan aparèy chofaj lè a ta dwe pwòp epi sèk, ak materyèl la nan pati a an kontak ak lè a nan aparèy chofaj la dwe omwen SUS304 klas;
2. Paske sous lè a nan pwosesis nòmal la bay yon COMPRESSOR lè oswa yon antilatè Rasin, aparèy chofaj lè a ta dwe chwazi yon tiyo-tip chofaj ak presyon-kapasite pote;
3. Faktè tankou volim lè, diferans tanperati, ak pèt chalè pandan transpò tiyo yo ta dwe konsidere an detay nan seleksyon an nan aparèy chofaj;
4. Pwosesis fonn-soufle a gen pi wo kondisyon sou presizyon kontwòl tanperati aparèy chofaj lè a. An tèm de kontwòl tanperati, yo ta dwe chwazi yon modil ki gen pi wo presizyon kontwòl tanperati, ak diferans espesifik tanperati sifas la se gwo, ki afekte estabilite nan tanperati lè a;
