Product details
Danfoss RT1A Pressure Switch | -0.5 to 7 bar | Ammonia (R717) | 017-500266
Product Description: The RT1A (017-500266) is engineered for precision in the most demanding industrial environments. In the UAE—where massive ammonia-based cold stores, dairies, and district cooling plants are standard—this switch provides reliable monitoring of suction or discharge pressures. With a regulation range of -0.5 to 7 bar, it is typically used for low-pressure control or compressor cycling. The stainless steel construction ensures it is immune to the corrosive nature of ammonia. Its IP66-rated enclosure provides ultimate protection against the high humidity and fine dust found in Jebel Ali and other industrial coastal areas, ensuring a long service life and high repeatability.
Key Features & Benefits:
- Ammonia (R717) Compatible: Features stainless steel sensing elements (bellows) specifically designed to resist ammonia corrosion.
- Exceptional Environmental Protection: IP66-rated housing is dust-tight and resistant to powerful water jets, essential for humid UAE engine rooms.
- SPDT Contact System: Includes a Single Pole Double Throw switch, allowing for versatile control of compressors, fans, or alarm circuits.
- Adjustable Differential: Allows for precise setting of “cut-in” and “cut-out” pressures to optimize system efficiency and reduce wear.
- Mechanical Reliability: The RT series is world-renowned for its “fit and forget” durability, often operating for decades in vibrating industrial settings.

FAQs:
- Q: Can the RT1A be used with standard HFC refrigerants like R134a?
- A: Yes, while it is optimized for Ammonia, its stainless steel bellows make it compatible with all standard non-flammable refrigerants used in the UAE.
- Q: Is it suitable for marine refrigeration in Abu Dhabi?
- A: Absolutely. Its robust IP66 casing and corrosion-resistant bellows make it an ideal choice for the salty, humid conditions of the maritime industry.
- Q: Does this model have a manual reset?
- A: No, the 017-500266 is an automatic reset model. It will switch back automatically once the pressure moves past the differential setting.
