Danfoss KP7ABS Dual Pressure Switch | For Ammonia (R717) & Fluorinated Refrigerants

Product Description:

The Danfoss KP7ABS (060-120566) is engineered for mission-critical safety in UAE ammonia (R717) and fluorinated refrigerant systems. This dual pressure switch provides both low-pressure regulation and high-pressure safety cut-out in one robust unit. The “ABS” designation signifies a premium safety version: it includes a fail-safe double bellows system on the high-pressure side—if the inner bellows leak, the outer bellows will still trigger a system shutdown, preventing hazardous situations. With a high-pressure range up to 32 bar, it is the industry standard for large-scale Dubai ice plants, cold storage, and chemical processing facilities where uncompromising safety and vibration resistance are mandatory.

Key Features & Benefits:

• Ammonia & Fluorine Compatible: Features high-grade stainless steel bellows, making it versatile for both R717 and HFC systems in the UAE.
• Double Bellows Safety: Provides an extra layer of protection; a sensing element failure will still trip the switch, safeguarding UAE personnel and equipment.
• Dual Functionality: Combines suction pressure control and high-pressure limit protection to save space and installation costs in Dubai.
• Trip-Free Manual Reset: High-pressure side requires a manual reset, ensuring the fault is inspected before the compressor restarts.
• Vibration Resistant Snap-Action: High-quality contacts minimize bounce and ensure stable operation near heavy industrial machinery.

FAQs:

• Q: What is the benefit of the “ABS” model over a standard KP15 in Dubai?
• A: The KP7ABS offers the double bellows safety system on the high-pressure side, which is often a requirement for high-risk industrial ammonia sites in the UAE.
• Q: Can it handle the high temperatures of a Dubai plant room?
• A: Yes, it is rated for ambient temperatures up to 65°C, ensuring reliable safety performance even during the peak summer months.
• Q: Is the reset “Trip-free”
• A: Yes, even if the reset button is held down, the switch will still trip if the pressure exceeds the safety limit, providing true safety for UAE operators.
