Danfoss KVR 22 Condensing Pressure Regulator | 5.0 to 17.5 bar | 7/8 in ODF |
Product Description:
The Danfoss KVR 22 (034L0094) is a robust solution for maintaining system efficiency across the UAE‘s diverse operating conditions. By regulating the refrigerant flow from the condenser, it ensures that a minimum condensing pressure is maintained, which is vital for the proper functioning of expansion valves and preventing “low pressure” trips during cooler Dubai nights. The KVR 22 is specifically sized with 7/8 in ODF connections to handle higher refrigerant mass flows in medium-sized chillers and supermarket racks. It features a built-in damping mechanism to eliminate pressure pulsations and noise, providing a stable and quiet operation. Constructed with high-grade materials and a hermetic seal, it is built to withstand the intense heat and humidity of the Middle East.
Key Features & Benefits:
- Enhanced System Stability: Maintains constant condensing pressure, preventing flash gas and ensuring consistent cooling in the UAE.
- Large Capacity Connection: 7/8 in ODF (solder) connections are ideal for larger piping systems and higher BTU loads in Dubai.
- Precise Control Range: 5 to 17.5 bar adjustable range allows for optimized performance with various HFC and HCFC refrigerants.
- Hermetic Design: Laser-welded construction minimizes the risk of refrigerant leaks, a critical factor for UAE environmental standards.
- Pulsation Damping: Internal damping ensures the regulator operates smoothly, extending the life of the entire refrigeration circuit.

FAQs:
- Q: When should I upgrade from KVR 12 to KVR 22 in a UAE project?
- A: Choose the KVR 22 when your system pipe size is 7/8 inch or when the mass flow requirement exceeds the capacity of the KVR 12 to avoid excessive pressure drops.
- Q: Can the KVR 22 be used with R410A in Dubai?
- A: No, the KVR series is rated for a maximum working pressure of 28 bar. For high-pressure R410A systems, specialized high-pressure regulators are required.
- Q: Does the orientation of the valve matter during installation?
- A: It is recommended to install it with the flow in the direction of the arrow on the valve body. In UAE installations, mounting with the adjustment screw accessible for maintenance is key.
