The switch is calibrated to a fixed open temperature of 140 degrees F
For optimal service life and to prevent debris accumulation
System Protection: Rapidly detects venting restrictions to protect the heat exchanger and prevent flame rollout
making it suitable for 3-phase commercial refrigeration and global industrial power standards
Using this on R410A systems may exceed the pressure rating of the internal gaskets
Advanced Distributor Products 176799953 Piston THPU32HP7Y The switch is calibrated toThe ADP 176799953 is a precision engineered #53 ton piston designed for reliable refrigerant metering in residential HVAC systems. Also known as a fixed orifice metering device, this genuine ADP replacement part is critical for maintaining the correct pressure drop between the high and low sides of the cooling circuit. Specifically sized for 1. 5 ton R22 or 2 ton R410A evaporator coils, it ensures the optimal flow of refrigerant to maximize heat
