Danfoss KP1A Low Pressure Switch | For Ammonia (R717) | -0.2 to 7.5 bar

Product Description:

The Danfoss KP1A (060-116066) is a critical safety and control component for ammonia-based cooling across the UAE. Built with specialized steel bellows to resist the corrosive effects of R717, it monitors the suction side of the compressor to prevent operation at dangerously low pressures. With a versatile range of -0.2 to 7.5 bar, it is widely used in Dubai’s large-scale cold stores and food processing facilities for both pump control and low-pressure safety cut-out. The KP1A features a high-load snap-action contact system that ensures an ultra-short bounce time, maintaining the electrical integrity of the control panel even in high-vibration industrial environments. Its rugged design is optimized to provide long-term stability in the extreme ambient conditions of the Middle East.

Key Features & Benefits:

• Ammonia (R717) Optimized: Features high-grade bellows and materials specifically designed for ammonia, the standard for UAE industrial cooling.
• Versatile Suction Control: Broad range (-0.2 to 7.5 bar) allows for precise setting of suction pressure limits in Dubai’s industrial racks.
• Snap-Action Contacts: Delivers an ultra-short bounce time to ensure stable signal output and extend the life of the electrical system.
• Vibration Resistant: Engineered to withstand the mechanical stresses of mounting directly near large industrial compressors in the UAE.
• Automatic Reset: Typically features an auto-reset function, allowing the system to restart once safe suction pressure is restored in Dubai operations.

FAQs:

• Q: Why use KP1A instead of a standard KP1 in a Dubai project?
  • A: The KP1A is “Ammonia Ready.” Standard KP1 models use copper/brass components which would be destroyed by ammonia; the KP1A uses steel parts required for UAE R717 sites.
• Q: What is the primary role of KP1A in UAE industrial plants?
  • A: It primarily acts as a safety device to prevent the compressor from pulling a vacuum, which could suck in air and moisture, leading to system contamination.
• Q: Is the M10 connection standard in the UAE?
  • A: Yes, the M10 x 0.75 thread is the standard for ammonia pressure switches in Dubai and is typically used with 6mm or 1/4″ steel tubing.
