Features of Semiconductor Chillers

• Siemens S7-1200 PLC controller, support programming, 5 programs, each program 40 steps.
• Danfoss, Emerson accessories (drying filter, oil separator, high and low pressure protector, expansion valve).
• Emerson and other international brands are selected for refrigeration accessories, with stable performance.
• PT100 or 4 ~ 20mA or communication given, USB and Ethernet interface, high adaptability.
• The pressure of refrigeration system adopts pointer pressure gauge, and the pressure of circulating system is detected and displayed on the touch screen by pressure sensor.
• With self diagnosis function, phase sequence protector, chiller overload protection, high voltage pressure switch, overload relay, thermal protection device and other safety protection functions.

Advantages of Semiconductor Chillers

Structure Design

A fully closed piping design, high efficiency plate heat exchanger used to reduce the demand for the thermal fluid utilization while providing the system to achieve the rapid ups and downs in temperature.

The whole system is a closed liquid circulation system with the expansion of container, expansion of the container and the liquid circulation is adiabatic, and do not participate in liquid circulation, only mechanical connection, regardless of the temperature is a high temperature or low temperature, the tank temperature is limited to 60℃.

Display Function

1. Display all the kind of process control temperatures.
2. Shows the liquid level of the heat conducting medium in the expansion vessel.
3. Shows indication for refrigeration system working.
4. Shows indication for heater working.
5. Shows indication for circulation pump working.
6. Display the temperature control.
7. The temperature upper limit, lower limit control can be set.
8. The temperature difference between jacket & reactor material can be set.
9. Shows the alarm to add the liquid when it is empty.
10. The refrigeration compressor can be set to operate manually or automatically.
