Danfoss CPCE 12 Hot Gas Bypass Regulator | 0.0 to 6.0 bar | 1/2 in ODF |

Product Description:

The Danfoss CPCE 12 (034N0082) is engineered to prevent the evaporator pressure from falling too low during periods of light load, a critical function for maintaining system stability in UAE‘s variable HVAC demands. By bypassing hot gas from the high-pressure side to the low-pressure side (typically after the expansion valve), it ensures the compressor remains within its safe operating envelope and prevents short-cycling. The CPCE 12 is designed to work in conjunction with a liquid-gas mixer (LG) to ensure that the bypassed gas does not overheat the suction line. Its robust, hermetic construction and high-grade bellows ensure long-term reliability and precise regulation even in the extreme ambient temperatures of Dubai.

Key Features & Benefits:

• Precise Capacity Regulation: Effectively matches compressor output to varying loads, ensuring stable operation in UAE commercial facilities.
• Compressor Protection: Prevents excessively low suction pressures that can lead to compressor overheating or oil return issues in Dubai.
• Improved Temperature Control: Minimizes temperature fluctuations in the cooled medium by providing continuous modulation instead of on/off cycling.
• Hermetic Solder Design: 1/2 in ODF connections provide a secure, leak-proof integration for UAE‘s professional refrigeration racks.
• Wide Adjustment Range: 0.0 to 6.0 bar setting allows for fine-tuning across different refrigerants like R134a and R404A.

FAQs:

• Q: Why is CPCE 12 important for air conditioning systems in Dubai?
• A: During periods of low cooling demand (like winter or nighttime), the CPCE 12 prevents the evaporator from freezing and keeps the compressor running smoothly without frequent starts and stops.
• Q: Do I need an LG mixer with the CPCE 12 in the UAE?
• A: Yes, for the best performance and to prevent high discharge temperatures, it is highly recommended to use the CPCE with a Danfoss LG liquid-gas mixer.
• Q: Is it compatible with newer low-GWP refrigerants?
• A: Yes, the CPCE 12 is compatible with most non-flammable HFC and HFO blends currently used in the UAE market.
