PRESSURE CONTROL KP1

Description

Item Description: Danfoss KP1 Low Pressure SwitchThe Danfoss KP1 is a highly reliable, single-bellows low-pressure control switch designed to protect refrigeration, air conditioning, and fluid systems from operating at dangerously low suction pressures.It functions primarily as a safety cut-out mechanism:Low-Pressure Protection: It constantly monitors the system’s low-pressure side. If a refrigerant leak occurs, a coil freezes, or the pressure drops below a safe limit, the switch breaks the electrical circuit.Compressor Safety: By cutting the power, it prevents the compressor from running dry, overheating, or suffering severe mechanical failure.Reset Style: Depending on the specific model code (such as the standard 060-110166), it features an Automatic Reset (which safely restarts the compressor once pressures stabilize) or a Manual Reset (requiring a technician to physically press a reset button before the machine can run again).Compatible Mechanisms & MachineryThe KP1 acts as a primary control interface across a broad spectrum of commercial, industrial, and automotive machinery:1. HVAC & Refrigeration CompressorsHermetic and Semi-Hermetic Compressors: Directly hooks into the control circuit contactors of major compressor brands (such as Copeland, Bitzer, Tecumseh, and Danfoss) to handle safety trip-outs.Scroll & Piston Machinery: Universally used in commercial cold rooms, supermarket display cases, liquid chillers, and industrial ice makers.2. General Industrial Pump and Turbine MechanicsWater & Booster Pumps: Frequently used in commercial water delivery systems to act as a “dry-run” protection switch, shutting off pump motors if the incoming water supply pressure fails.Air & Gas Compressors: Integrated into pneumatic systems to maintain minimum functional pressure thresholds.Steam Power Plants & Boilers: Utilized as a low-limit pressure safety cut-off in specialized steam loop mechanisms and steam turbines.3. Refrigerant Gas SystemsThe internal bellows are structurally rated to handle standard non-corrosive, fluorinated refrigerants. It is fully compatible with:Standard CFC/HCFC/HFCs: R22, R134a, R404A, R407A, R407C, R407F, R422B, R422D, R507A.Eco-Friendly HFOs: R1234yf, R1234ze(E), R448A, R449A, R450A, R452A, R513A.⚠️ Note: The standard KP1 copper-alloy bellows cannot handle corrosive gases. For Ammonia ($NH_3$) applications or highly corrosive environments, you must use the specialized Danfoss KP1A variant which features stainless steel connections.
