Danfoss RT260A Differential Pressure Switch | 0.5 to 4 bar | 017D002166
Product Description: The RT260A (017D002166) is engineered to monitor and control the pressure difference between two points in a system, typically used to ensure proper oil pressure in compressors or to monitor filter clogging in large industrial chillers. In the UAE—where massive ammonia-based cold stores and district cooling plants operate under extreme conditions—the RT series is favored for its exceptional reliability and repeatability. This model features a 0.5 to 4 bar regulation range and a manual reset function, providing an essential safety layer. The housing is built to withstand the humid and corrosive atmospheres found in Jebel Ali and other industrial coastal zones in the Emirates.
Key Features & Benefits:
- Ammonia (R717) Compatible: Specially designed with materials that resist corrosion from ammonia, making it ideal for large-scale UAE industrial refrigeration.
- High Reliability: The RT series is known for its long mechanical life and precision, even in the high-vibration environments of UAE plant rooms.
- Manual Reset Function: Enhances system safety by requiring a manual intervention if the pressure differential exceeds the set limits.
- Adjustable Differential: Allows for fine-tuning of the operating range to meet specific system requirements.
- IP66 Enclosure: Provides a high degree of protection against dust and powerful water jets, essential for maintaining electrical integrity in humid UAE environments.

FAQs:
- Q: Is the RT260A suitable for sea-water cooled condensers in Abu Dhabi?
- A: Yes, its IP66 rating and robust construction make it highly resistant to the saline air and humidity found near the coast.
- Q: Can this be used with standard HFC refrigerants?
- A: Absolutely. While optimized for Ammonia, it is fully compatible with R134a, R404A, and R507.
- Q: What is the benefit of the manual reset?
- A: It ensures that a technician must inspect the system for the cause of a pressure differential issue before the equipment can be restarted, preventing potential compressor damage.
