Carrier HK02ZA436 Pressure Switch 318172-701 suggesting the refrigerant filter drierThe Carrier HK02ZA436 is a professional grade high pressure switch engineered for critical refrigerant monitoring in industrial refrigeration and air conditioning systems. As an essential safety component, this HVAC pressure switch features a 290 PSI cutout and a 185 PSI cut in, providing a precise 290 185 pressure range. When system pressure exceeds the preset limit, the switch breaks the electrical circuit to the compressor, preventing catastrophic
