Ultra High Pressure Brazed Plate Heat Exchangers for CO₂ Refrigeration Systems
As industrial refrigeration increasingly adopts CO₂ (R744) , system pressure becomes one of the most critical engineering factors. HEXNOVAS Ultra High Pressure Brazed Plate Heat Exchangers are designed specifically for high-pressure refrigeration environments where reliability, compact design, and thermal efficiency are essential.
Application Background – CO₂ Refrigeration in Food Processing
Modern food processing plants increasingly adopt CO₂ refrigeration systems due to their excellent environmental performance and energy efficiency. However, CO₂ systems operate at significantly higher pressures than traditional refrigerants, especially in transcritical operation.
In such systems, heat exchangers must withstand high pressure conditions while delivering stable heat transfer performance. HEXNOVAS Ultra High Pressure BPHE units are engineered to meet these requirements in demanding industrial refrigeration environments.
Example of CO₂ Refrigeration Systems Using Plate Heat Exchangers
The following examples illustrate typical industrial refrigeration installations where plate heat exchangers are integrated within skid-mounted refrigeration systems.
Engineering Challenges in CO₂ Systems
- High operating pressure compared with traditional refrigerants
- Pressure cycling caused by load variations
