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.
izberite:
1. Zrak, potreben za procesni tok, je čist. Prvič, vhodni vir zraka v grelnik zraka mora biti čist in suh, material dela, ki je v stiku z zrakom v grelniku, pa mora biti najmanj razreda SUS304;
2. Ker vir zraka v običajnem procesu zagotavlja zračni kompresor ali Roots puhalo, mora grelnik zraka izbrati cevovodni-grelnik s tlačno-nosilnostjo;
3. Pri izbiri grelnikov je treba podrobno upoštevati dejavnike, kot so prostornina zraka, temperaturna razlika in toplotne izgube med transportom po cevovodih;
4. Postopek-pihanja taline ima višje zahteve glede natančnosti nadzora temperature grelnika zraka. Pri nadzoru temperature je treba izbrati modul z večjo natančnostjo nadzora temperature, specifična temperaturna razlika površine pa je velika, kar vpliva na stabilnost temperature zraka;
