this limit switch protects the heat exchanger and blower motor from overheating conditions

Durable Core Design: Heavy-duty laminations and windings minimize humming and heat generation during high-demand cycles

If your one-pipe thermostat is unable to reduce branch pressure or if the controlled valve slams and stays in one position regardless of the setpoint

If it trips repeatedly

Sporlan 902905P Control Refrigerant this limit switch protects theThe Sporlan 902905P is a high performance OROA 5 head pressure control valve designed specifically for air cooled condensing units operating in low ambient conditions. This non adjustable head pressure control ensures system reliability by throttling liquid flow from the condenser while simultaneously regulating hot gas bypass to the receiver. By maintaining a 100 PSI setting, the valve prevents common system failures such as iced evaporator coils and
