Industrial CO₂Cascade Refrigeration Unit

Product Introduction:

The Industrial CO₂ Cascade Refrigeration Unit is a high-performance ultra-low temperature refrigeration solution designed for industrial applications requiring stable cooling at extremely low temperatures. The system combines a high-temperature refrigeration circuit using conventional refrigerants such as R404A or R134a with a low-temperature CO₂ (R744) refrigeration circuit, creating an efficient cascade refrigeration system for demanding cold chain applications.

By utilizing the excellent low-temperature characteristics of CO₂, this refrigeration unit provides reliable cooling performance in the range of -40°C to -70°C, making it an ideal solution for blast freezing, ultra-low temperature storage, tuna freezing, seafood processing, and other industrial refrigeration projects.

PRODUCT DESCRIPTION

Key Features

· Excellent Ultra-Low Temperature Performance

The CO₂ cascade refrigeration technology delivers high efficiency and stable operation at extremely low temperatures. It is especially suitable for applications requiring -40°C, -55°C, and -60°C temperature conditions, where traditional single-stage or two-stage refrigeration systems may have limitations.

The excellent heat transfer performance of CO₂ allows smaller evaporators and more compact refrigeration equipment while maintaining high cooling capacity.

· Environmentally Friendly CO₂ Natural Refrigerant

CO₂ (R744) is a natural refrigerant with zero ozone depletion potential (ODP) and extremely low global warming potential (GWP). It meets increasingly strict global environmental regulations and provides significant advantages for international export refrigeration projects.

CO₂ is non-flammable and non-toxic, offering excellent safety performance compared with many synthetic refrigerants.

· High Heat Transfer Efficiency

CO₂ has superior thermophysical properties and a high heat transfer coefficient, enabling more efficient heat exchange. Compared with conventional low-temperature refrigerants, the system can use smaller heat exchangers and reduced pipe sizes, saving installation space and improving overall system efficiency.

· Reliable Low-Temperature Operation

The CO₂ low-temperature circuit provides stable performance under extreme operating conditions. Its high-pressure characteristics and favorable low-temperature viscosity help improve oil return performance and ensure reliable long-term operation.

· Heat Recovery Capability

The heat released from the high-temperature circuit can be recovered and reused for:

· Hot gas defrosting

· Hot water production

· Facility heating applications

This improves energy utilization and reduces operating costs.

· Flexible Configuration and Professional Design

The Industrial CO₂ Cascade Refrigeration Unit can be customized according to project requirements, including compressor brands, cooling capacity, temperature range, control systems, and installation conditions.

High-quality compressors, heat exchangers, and refrigeration components ensure reliable operation for industrial applications.
