2. The air circuit is designed with upper and lower return air, wind speed and wind pressure all meet the test standards, and the temperature stabilizes quickly when the door is opened and closed.
3. Optimized ventilation design, strong air circulation, avoid any dead angle, and make the temperature distribution in the room even.
4. More energy-saving and meet current international and domestic environmental protection requirements.
5. More silent, ≤55dB, better guarantee a good office environment and the working environment of the operator.
6. The extremely small inner volume and ultra-small volume ensure the room is quiet, generous and beautiful.
7. Easy installation, maintenance and repair.
8. High quality and reasonable design.
9. All parts have extremely high reliability.
Fourth, the heating system:
1. High efficiency titanium alloy stainless steel electric heating tube imported from Japan. The heater is connected with high temperature resistant wire, which does not burn at 300 degrees.
2. The heating system adopts hot air circulation heating method, the temperature distribution is uniform, the system is completely independent, and does not affect the control circuit.
3. The temperature control output power is calculated by microcomputer, and the heating power is automatically controlled according to the internal load to achieve high-precision and high-efficiency power consumption benefits, more environmental protection and energy saving.
Five, circuit control system:
1.Adopt AZBIL-SDC23 series controller imported from Japan. (Fuji, Japan).
2. Wide and easy-to-use double-layer seven-segment display, high-brightness digital tube, so that the operator can see clearly at a long distance.
Values and other values are clearly displayed on two lines of nixie tubes.
3. With auto / manual, run / standby, RSP / LSP, contact lock cancellation, etc.
4. Custom parameter function: SDC23M provides "para" key as user-defined key. Up to 8 parameters can be assigned. This key is used to access and monitor common parameters without entering the menu.
5. Can directly display the temperature curve, and can be connected to a computer.
6. Has 3 independent self-tuning functions: ordinary self-tuning; fast response self-tuning, suitable for heating systems with fast response heaters; stability self-tuning, suitable for control systems that require stable control of small overshoot.
7. Block control: SDC23M / 24M can set up to 8 SP values. Each SP has hold time and slope settings. Up to 8 blocks (16 blocks) can be set for programmable control.
8. Time relay, can set the required running time, when the time is up, it will automatically stop.
9. The temperature control adopts the PID + SSR system synchronous and coordinated control, which can improve the stability and life of the control components and interfaces.
10. Control mode: PID (proportional-integral-derivative) automatic calculation, PID control is simple and easy to understand, and no prerequisites such as an accurate system model are required in use.
11. In the setting, if an error occurs, a warning signal will be provided.
12. Temperature sensor: DIN PT-100Ω (platinum induction).
Six, safety protection device
