Cooling system

The refrigeration system: composed of a semi-hermetic low-temperature compressor. The compressor has the characteristics of compact structure, low vibration, low noise, high energy efficiency ratio, and large cooling capacity under low temperature conditions. The optimized design of the refrigeration system reduced operating costs and increased reliability.
Compressor cooling method: water-cooled

Air ventilation

The centrifugal fan sends air horizontally, and adopts the design of left and right air outlet and middle return air. It is most suitable for the aging of test items in the room, which can effectively take away the heat of the test items themselves. The wind speed and wind pressure meet the test standards, and the temperature stabilizes quickly at the moment of opening and closing the door, ensuring uniform indoor temperature.

All electronic control components and circuits are equipped with markings and wire numbers to standardize electrical assembly and facilitate inspection and maintenance:

Heating System

Finned radiator tube nickel-chromium alloy U-shaped high-efficiency heater, automatic calculation of high-precision PID+SSR control (calculation cycle: 1~4S can be set), so that the heat loss is equivalent to the heating capacity, Heater control mode: non-contact and other periodic pulse width adjustment, SSR (solid state relay)

Control system

7-inch color touch screen with Chinese/English display + German Siemens control module. The controller adopts LCD color touch screen, and the control system adopts man-machine dialogue; it has an automatic, intelligent and humanized design. The control system adopts a two-way input and two-way output control mode to control the temperature, and can display the operating time, the working status of the heater, the refrigeration unit, and the fan. The heating system, refrigeration system, circulation fan and other subsystems can be automatically combined to ensure the high control quality of the entire temperature control system; the control system also has self-detection and self-diagnosis functions, and automatically displays faults and alarms.
RS-232 communication interface software. The system software is designed based on the Windows platform, and has a wide range of adaptability, security, reliability and advancement with other software and hardware. The display screen can directly display and set various operating parameters, operating time, working status of the refrigeration unit and heating system.
