Danfoss Refrigeration RT5A Pressure Switch
Product Introduction
The Danfoss RT5A 017-504666 is a pressure switch designed specifically for refrigeration applications, with a focus on ammonia systems and heavy-duty industrial use. As part of Danfoss’ extensive range of refrigeration and air conditioning solutions, it functions as a pressure control switch, featuring a single-pole double-throw (SPDT) contact design to monitor and regulate pressure in systems. With an IP65 enclosure rating and robust construction, it is built to withstand harsh environments, making it suitable for industrial and marine refrigeration setups. This switch supports both low and high-pressure control, ensuring safe and efficient operation of compressors, evaporators, and other refrigeration components. Its compatibility with fluoride and ammonia refrigerants further enhances its versatility in diverse cooling systems.
Features
Ammonia System Compatibility: Specifically designed for ammonia refrigeration systems, meeting the demands of industrial cooling applications.
SPDT Contact Function: Equipped with a single-pole double-throw switch, enabling flexible control logic (e.g., alarm, shutdown, or activation of auxiliary devices) based on pressure thresholds.
Wide Ambient Temperature Range: Operates in environments from -40 °C to 85 °C (-40 °F to 180 °F), adapting to extreme temperature conditions in refrigeration facilities.
Durable Enclosure: IP65-rated enclosure provides protection against dust and water jets, ensuring reliability in wet or dusty industrial settings.
Robust Sensing Element: Uses a bellows pressure sensing element, known for accuracy and durability in pressure monitoring applications.
Secure Connections: Features a 1/4-inch female pressure connection and wire connections suitable for 6-14 mm diameter cables (Pg 13.5), facilitating secure integration into system piping and electrical circuits.
Marine and Industrial Suitability: Part of the RT series, which is designed for heavy-duty use, including marine refrigeration applications, with resilience to vibration and harsh operating conditions.
CE Certification: Complies with CE standards, ensuring adherence to European safety and performance regulations.
