Danfoss KP1 Low-Pressure Switch Controller (Made by Danfoss):
- Technical Specifications: Regulating pressure range -0.2 to 7.5 bar (Pe) / (-2.9 to 108 PSI), adjustable differential (DIFF) range 0.7 to 4.0 bar, maximum working pressure (PB) 17 bar, proof test pressure 20 bar, reset function: Automatic Reset, contact system: Single Pole Double Throw (SPDT snap-action microswitch), electrical rating AC-1: 16A 400V / AC-3: 16A 400V / DC-13: 12W 220V, pressure connection G 1/4" Male flare / threaded, enclosure rating IP30 (IP44 with top cover), compatible with all fluorinated refrigerants (R22, R134a, R404A, R407C, R410A, R507A) and compressed air, Product of Danfoss Denmark.
- Ultra-Fast Snap-Action SPDT Electrical Contact Mechanism: Minimizes contact bounce and arcing, preventing compressor contactor chatter and extending electrical contact life.
- Dual Easy-To-Read Calibration Dials: Top-mounted pointer scales allow straightforward independent tuning of set-point cut-in and differential cut-out pressures.
- High-Reliability Low-Pressure Protection: Automatically shuts off refrigeration compressors when suction pressure drops below critical thresholds, preventing vacuum air intake and motor freeze-up.
- Robust Welded Bellows Sensing Element: Stainless steel / bronze pressure bellows withstands continuous pulsating compressor pressure cycles without fatigue.
- Vibration-Resistant Compact Industrial Design: Mounts securely onto commercial condensing units and HVAC chillers with excellent resistance to machine vibrations.
- Applications: Commercial cold room condensing units, HVAC water chillers, heat pumps, air compressor suction protection, and industrial refrigeration systems.
