Product characteristics of binary stacked ultra-low temperature refrigeration unit：

1. Using Bitzer imported compressors from Germany as the main engine, the main components are all internationally renowned brands. Combined with Siemsn industrial grade PLC and microcomputer control system from Germany, the system is safe and reliable, with a fully automatic control system and unmanned automatic alarm information function.

2. The binary stacked double ultra-low temperature refrigeration unit system is more optimized and stable, and can meet the demand for process cold sources in 24-hour continuous production in industrial production.

3. We can provide ultra-low temperature liquid cooling sources ranging from -135 ℃ to -40 ℃.
