Danfoss KVR 28 Condensing Pressure Regulator | 5.0 to 17.5 bar | 1 1/8 in ODF

Product Description:

The Danfoss KVR 28 (034L0095) is the professional choice for managing large refrigerant mass flows in the UAE‘s demanding climate. By throttling the condenser output, it maintains a constant minimum condensing pressure, ensuring the entire refrigeration system—especially the expansion valves—operates with peak efficiency during the cooler winter months or low-load periods in Dubai. With its large 1 1/8 in ODF solder connections, the KVR 28 is built for major installations such as large supermarket racks, industrial chillers, and warehouse cooling systems. It features an advanced internal damping system to prevent noise and vibration, and its hermetically sealed, robust construction ensures a long service life with zero maintenance in the high-heat environments of the Middle East.

Key Features & Benefits:

• Maximum Flow Capacity: Specifically designed for large-scale systems in the UAE that require 1 1/8 inch piping and high refrigerant throughput.
• Year-Round Reliability: Prevents low head pressure issues, ensuring consistent cooling performance in Dubai regardless of ambient temperature drops.
• Precision Performance: Fully adjustable from 5 to 17.5 bar to match the exact requirements of R134a, R404A, and other common HFCs.
• Hermetic Leak Protection: Laser-welded design provides a secure, permanent seal, reducing refrigerant loss and environmental impact in the UAE.
• Smooth Operation: Integrated damping mechanism eliminates chatter and pressure ripples, protecting the system’s mechanical integrity.

FAQs:

• Q: Is KVR 28 suitable for high-pressure CO2 systems in Dubai?
• A: No, the KVR 28 has a maximum working pressure of 28 bar. For CO2 or high-pressure applications, you should look into the Danfoss CCMT or specific high-pressure valves.
• Q: Can this be used for hot gas bypass in the UAE?
• A: While similar in look, the KVR is for condensing pressure. For hot gas bypass, the Danfoss KVC series is the correct choice for Dubai projects.
• Q: What is the best way to adjust the KVR 28 onsite?
• A: Use a high-quality pressure gauge on the condenser side and adjust the screw until the desired minimum head pressure is reached during low ambient conditions.
