Danfoss KVR 12 Condensing Pressure Regulator | 5.0 to 17.5 bar | 1/2 in ODF

Product Description:

The Danfoss KVR 12 (034L0093) is an essential component for maintaining system stability in the UAE‘s variable climate. It functions by throttling the flow of refrigerant from the condenser, ensuring that the condensing pressure remains at a constant level even when ambient temperatures drop (such as during winter nights in Dubai). This is critical for ensuring that the thermostatic expansion valve (TXV) has enough pressure drop to operate correctly. The KVR 12 is often used in conjunction with a KVD receiver pressure regulator to provide a complete “head pressure control” solution. Built with a hermetic construction and featuring a damping mechanism to prevent pulsations, it ensures long-term reliability in demanding Middle Eastern commercial refrigeration applications.

Key Features & Benefits:

• Constant Head Pressure: Ensures reliable system operation year-round in the UAE, regardless of ambient temperature fluctuations.
• Precision Adjustment: A broad setting range of 5 to 17.5 bar allows for fine-tuning based on specific refrigerant requirements in Dubai.
• Vibration Damping: Specially designed to eliminate chatter and noise, protecting the piping system from mechanical stress.
• Hermetic Solder Connection: 1/2 in ODF (solder) connections provide a permanent, leak-proof seal for UAE installations.
• Compact Design: Easy to install in tight condensing unit housings while providing high flow capacity.

FAQs:

• Q: Why do I need a KVR 12 in a hot climate like the UAE?
• A: While Dubai is usually hot, night-time temperatures or seasonal changes can cause condensing pressure to drop too low, leading to “flash gas” and poor cooling performance. The KVR 12 prevents this.
• Q: Where should the KVR 12 be installed?
• A: It should be installed in the liquid line between the condenser and the receiver, or in the discharge line after the oil separator.
• Q: Is it compatible with the new low-GWP refrigerants in Dubai?
• A: Yes, the KVR 12 is compatible with most standard non-flammable HFC and HFO blends commonly used in the UAE market.
