Danfoss 060-203191 Pressure Controller

The Danfoss 060-203191 is a high-performance KP15 dual pressure switch designed for safety monitoring and control in commercial refrigeration and air conditioning systems. Engineered as the direct 060-203166 replacement, this controller features a dual-signal output to manage both high-pressure cutout and low-pressure control within a single compact housing. It utilizes SPDT plus LP signal switching logic, allowing for independent operation of the compressors and alarm circuits. The low-pressure side offers a regulation range of -0.2 to 7.5 bar with an adjustable differential, while the high-pressure side provides a 10 to 30 bar range with fixed 4 bar differential and manual reset functionality. This HVAC pressure controller is compatible with HCFC and non-flammable HFC refrigerants, featuring 1/4 inch flare connections and ultra-short bounce times to protect contact integrity. For contractors troubleshooting short-cycling or discharge pressure spikes, the 060-203191 ensures millisecond-accurate response to system fluctuations.

• Vibration Resistant: Trip-free snap-action contacts minimize wear and prevent contact welding during heavy compressor vibration.
• Dual Functionality: Combines low-pressure safety and high-pressure limit control, reducing piping complexity and installation footprint.
• Manual High-Pressure Reset: Ensures system inspection is required after a high-pressure event, protecting the compressor from repeated stress.
• Broad Compatibility: Rated for a wide range of refrigerants including R404A, R134a, R407C, and R507.
• Enhanced Durability: Robust bellows construction designed for high-cycle industrial applications and harsh mechanical rooms.

Is the 060-203191 compatible with R410A systems?
No, this model is rated for a maximum working pressure (MWP) of 17 bar on the LP side and 35 bar on the HP side; R410A systems typically exceed these parameters. Use the KP6 or KP17 series for high-pressure R410A applications.

How do I wire the independent alarm signal?
The SPDT contact system includes a dedicated terminal that closes upon a low-pressure trip, allowing you to trigger a remote alarm or PLC input while simultaneously breaking the compressor contactor circuit.

What is the difference between this and the 060-203166?
The 060-203191 is the updated technical successor, maintaining identical mounting footprints and electrical ratings while meeting current manufacturing standards for improved bellows longevity.
