c) Controller specifications

Technical indicators:

1. 7-inch color touch screen

2. Two control modes: program/fixed value

3. Sensor type: two PT100 inputs (electronic sensor input optional)

4. Output mode: voltage pulse (SSR)/control output: 2 (temperature/humidity)/2 4-20mA analog output/16 relay outputs (passive)

5. Control signal: 8 IS control signals/8 T control signals/4 AL control signals

6. Alarm signal: 16 DI external obstacle alarms

10. Interface language type: Chinese/English

11. Equipped with English input function

12. Can be used with a printer (USB function optional)

13. A variety of signal combination relay outputs, and the signals can be subjected to logical operations (NOT, AND, OR, NOR, XOR), referred to as PLC programming ability

14. Diversified relay control methods: parameter->relay mode, relay->parameter mode, logic combination mode, composite signal mode

15. Program editing: 120 groups of programs can be programmed, and each group of programs can program up to 100 segments

Cooling system
Operation mode Air-cooled mechanical compression single-stage refrigeration mode
Heating and cooling devices

1. Hitachi or Emerson low-temperature and low-noise scroll compressor (air-cooled heat dissipation method).

2. Cooling method: air cooling
Heat and cold exchange device Single-stage refrigeration system, Emerson low-temperature and low-noise scroll compressor imported from the United States. Adopting ultra-high-efficiency SWEP cold coal heat and cold exchange design [made in Sweden (sus#316)], it is more efficient than the traditional internal spiral type.
Heating load adjustment

1. The automatic adjustment of the cold coal flow rate device is adopted to effectively take away the heating load of the product to be tested, which is synchronized with German/Japanese technology.

2. Compared with traditional designs, the control stability and reproducibility are higher, and it achieves ultra-high performance in terms of power saving and energy saving.
Refrigeration compressor

Hitachi or Emerson low temperature and low noise scroll compressor
