About this product

Product advantages

1. The software: PID calculation is used to calculate accurately control the cooling capacity, making the temperature stable, and applying different loads and their heat generation within the capacity range of the refrigeration system.

2. The refrigeration system adopts cold system (R404 and R23) and adopts electronic expansion valve for energy-saving control to reduce energy consumption (about 40%~50%).

3. Temperature and humidity control range is wide (-70~180℃ & 10%~98%R.H)and accurate control(0.01℃).

4. Mitsubishi PLC + industrial-class man-machine interface, equipment with strong anti-interference, the system is stable and reliable, and low failure rate. After the fault occurs, the equipment alarm is the corresponding processing method of intelligent prompt fault, automatically record the equipment operation data and fault information to help customers to quickly troubleshoot faults and restore the equipment normal operation.

Product details

Suitable objects include metal, plastic. Rubber, electronics and other materials, it can be used as product improvement base or reference.

Technical advantages

1. Adopted temperature and humidity controller with independent intellectual property right.

2. Adopted Mitsubishi PLC+ industrial-level man-machine interface, with strong anti-interference, stable system and low failure rate.

3. Man-machine interactive output operation, recording equipment operation data and fault information automatically.

4. Historical data of temperature and humidity is exported by U disk, and also EXCEL format table or BMP format image output can be selected with easy operation.

5. Intelligent prompt corresponding processing method for fault.

6. Adopted PID+ fuzzy control method to save energy and wide range of temperature and humidity control.

7. Wide range of temperature and humidity control.

8. Refrigeration system adopts cold system (R404 and R23). Adopted electronic expansion valve energy saving control, through the software automatic adjustment of valve opening to achieve the stability of temperature, low temperature (below 0℃) stability process heater does not work, the compressor with refrigeration flow reduced power consumption correspondingly reduced, to achieve the purpose of energy saving (about 40~50%).
