Danfoss KP15A Dual Pressure Switch | For Ammonia (R717) & Fluorinated Refrigerants |
Product Description:
The Danfoss KP15A (060-129466) is a high-performance dual pressure switch featuring both low-pressure (LP) and high-pressure (HP) control in a single unit. Specifically engineered for the UAE‘s industrial cooling sector, the KP15A is equipped with high-grade bellows that are compatible with Ammonia (R717), making it essential for food processing and large-scale ice plants in Dubai. This switch provides reliable protection against excessively low suction pressure and dangerously high discharge pressure. Its “trip-free” manual reset function ensures that the system cannot be restarted until the fault is cleared, providing an extra layer of safety for expensive compressor racks. The compact design and high-contact load capacity make it the preferred choice for Middle Eastern engineers who demand durability in extreme ambient conditions.
Key Features & Benefits:
- Ammonia Compatible: Features special bellows and connections (M10 x 0.75) designed to handle R717, a common refrigerant in UAE industrial plants.
- Dual Protection: Combines suction and discharge monitoring in one compact device to save space and reduce installation time.
- Trip-Free Safety: Ensures the compressor stays offline after a high-pressure trip until a manual reset is performed by a technician.
- Vibration Resistant: Built to withstand the mechanical stresses of mounting directly on or near large industrial compressors in Dubai.
- Ultra-Short Bounce Time: High-quality snap-action contacts minimize wear and electrical noise, extending the life of the control system.

FAQs:
- Q: Can the KP15A be used with standard copper pipes in the UAE?
- A: For Ammonia (R717) applications, steel or aluminum piping is mandatory. The KP15A features a steel connection suitable for these systems.
- Q: What is the benefit of the manual reset on the HP side?
- A: It forces a manual inspection if the system hits a high-pressure limit, which is critical for preventing compressor damage during the extreme UAE summers.
- Q: Is this switch weather-resistant for outdoor installation?
- A: It comes with a standard IP44 rating when the top cover is fitted. For high-humidity areas in Dubai, an additional protective housing is recommended.
