The CO2 cascade system is mainly used in large and medium-sized food processing, quick freezing, and
Contact UsTechnical features:
1. Green and environmentally friendly
The secondary refrigeration system uses natural refrigerant CO2 as the refrigerant, with an ODP (Ozone Depletion Index) of 0 and a GWP (Greenhouse Effect Index) of 1, which is environmentally friendly.
2. Intelligent control
Siemens PLC is used to automatically control the start and stop of the unit and the number of machine heads running based on production load and suction pressure.
3. Safe and reliable
The unit adopts internationally renowned brands of equipment and accessories, such as Bitzer compressors, Danfoss automatic control valves, Alfa Laval plate exchangers, Haimitick fluorine pumps, Siemens PLCs, and other high-quality products, ensuring the safety and reliability of the equipment.
Adopting a multi head parallel assembly method, even if a single head fails, other heads can continue to operate without affecting the use of the entire system.
4. Efficient and energy-saving
Multiple machine heads are connected in parallel, providing flexible energy regulation. The unit can automatically adjust the number of units put into operation according to changes in production load, ensuring that the unit is always in the best state.
5. Reduce investment
The pry block unit integrates the compressor head and barrel pump unit, reducing the footprint and lowering investment costs.
Main application scope:
The CO ₂ stacked pry block unit is a refrigeration unit developed for single freezer cold sources.
The CO ₂ stacking block unit can also be used in low-temperature refrigeration and freezing systems with evaporation temperatures ranging from -30 ℃ to -45 ℃.
The COz compressor in the CO ₂ stacking block unit adopts a Bizelle semi closed piston compressor head
The Freon compressor adopts a Bizel integral screw.
