Five, the circulation system:
Hot air circulation method: Horizontal circulation air is used, side air is forced, blown out by the hot air on the right side of the working room, and returned by the left side of the working room. The hot air circulation is forced by the top fan to achieve uniform temperature.
Centrifugal wind wheel: high temperature resistant long shaft oven motor with multi-wing centrifugal mute wind wheel, shockproof and self-radiating.
Noise index: The noise of a single device is ≤60dB.
Electrical control box: using independent hanging control box, installed on the side of the machine, left and right can be selected;
Temperature control device: The intelligent temperature controller is adopted. The controller is a dual-row LED digital display / PID control / automatic calculation / film button setting / control accuracy ± 1% FS.
Temperature measuring device: The stainless steel K-type thermocouple temperature sensing device is adopted for sensitive and accurate temperature measurement and long service life.
Timing device: 4-digit LED time display with intelligent digital display 0 ~ 9999 (hour / minute / second can be switched) and alarm function When the temperature in the oven reaches the temperature set value of the main control instrument, the timer starts automatically Timing, when the time reaches the set value, the red sound and light alarm automatically alarms to indicate the end of the work.
Alarm device: APT / AD16 timing alarm, sound and light alarm prompt at the end of constant temperature time, heating is cut off at the same time, the timer is controlled by the switch, if you need to continue heating after the timer is over, you need to restart the timer. Over-temperature alarm, when the temperature in the box reaches the set limit temperature value, it will start the buzzer alarm and cut off the heating, until the temperature returns to the normal state, it will automatically cancel the alarm state and continue to work.
Seven, perfect security protection measures:
Residual current circuit breaker, over-temperature protection, motor over-current protection, machine buzzer warning, etc.
Eight, equipment use conditions:
9.1 Environmental conditions: temperature—5 ～ 40 ℃; humidity ≤85% RH;
9.2 Power supply: AC380V 50HZ three-phase five-wire system
