Product description
Parameters
The RX (FD) series of cascade refrigeration units are designed to provide users with low temperature brines for recycling from -35 ° C to -80 ° C.
This product is suitable for all kinds of chemical, mechanical, pharmaceutical and other industries where low temperature brine is required as a refrigerant.
1. Compressor: Bock.Bitzer imported from Germany has stable performance and low failure rate. Refrigerant: low temperature environmentally friendly refrigerant R404A/R23
2. German siemens industrial grade PLC + color LCD touch screen control system, with high degree of automation, precise control and unattended value. Can meet the 24-hour continuous production needs.
3. Convenience: The unit adopts advanced PLC control technology to realize one-button automatic operation. We can also realize multi-machine joint control and remote control according to your requirements.
4. The unit has been calibrated and the whole machine is qualified for delivery. The user can simply use the water source and power supply to use.

Note:
1. The cooling capacity is measured under the following temperature conditions: the coolant is alcohol; the cooling water inlet/outlet temperature is 32/37 °C.
2. Working range:
Cooling water outlet temperature is 22 ° C to 37 ° C
Cooling water inlet temperature difference is 3.5 ° C to 10 ° C
Freezing fluid outlet temperature is -40 ° C to -80 ° C
The temperature difference between the inlet and outlet of the freezing liquid is 2.5 ° C to 10 ° C
3, the factory is equipped with pairs of cooling water, freezing fluid inlet and outlet connection flange, the carrier (alcohol) by the user.
4. The above specifications are subject to change without prior notice. This will help our company to bring the latest scientific and technological achievements to customers at any time.
