Product details
Danfoss RT5AL Pressure Switch | 4.0 to 17.0 bar | Neutral Zone
Product Description:
The Danfoss RT5AL (017-004066) is a specialized high-tier controller engineered for the complex demands of the UAE’s industrial sector. This “L” series model features an Adjustable Neutral Zone, which allows for a set pressure range where no switching occurs. This is vital for preventing compressor “hunting” and unnecessary cycling in large-scale Dubai cooling plants, especially during the high-load summer months. With a range of 4.0 to 17.0 bar, it is ideally suited for discharge side regulation. Its IP66-rated enclosure and ammonia-resistant bellows ensure that the unit remains accurate and durable despite the humidity, sand, and corrosive atmospheres common in UAE industrial and maritime environments.
Key Features & Benefits:
- Neutral Zone Efficiency: Minimizes mechanical wear and energy consumption by creating a stable “dead band” in UAE high-pressure systems.
- Ammonia (R717) Ready: Specifically built for natural and fluorinated refrigerants, a standard for UAE‘s industrial cold chain.
- Heavy-Duty IP66 Housing: Provides complete protection against dust and high-pressure water jets in harsh Dubai environments.
- Industrial Stability: Designed to maintain precise trip points even on high-vibration compressor racks across the UAE.
- Flexible SPDT Contacts: Offers advanced wiring possibilities for multi-stage control or alarm systems in UAE plants.

FAQs:
- Q: Why is a Neutral Zone (RT5AL) better for large UAE chillers?
- A: It allows the pressure to fluctuate slightly within a safe range without triggering the switch, which reduces the start/stop frequency of large motors in the UAE, saving significant energy.
- Q: Can this 017L004066 model handle the heat of Dubai?
- A: Absolutely. It is rated for ambient temperatures up to +70°C, making it one of the most heat-resistant switches available in the UAE.
- Q: Is it easy to adjust the neutral zone in the field?
- A: Yes, UAE technicians can easily adjust both the main range and the neutral zone differential using the internal setting disks and visible scales.
