DAIKIN 2222611

DAIKIN 2222611 is a rugged refrigerant pressure switch / pressure sensor assembly for Daikin marine & industrial chiller / HVAC refrigeration system. The pressure switch assembly monitors refrigerant high/low pressure inside cooling circuit, provides dry contact protection signals to chiller controller. This pressure switch assembly is used to prevent compressor damage caused by overpressure or loss of refrigerant. The pressure switch assembly adopts vibration-resistant housing, salt mist approved design for marine air conditioning and refrigeration cabinets.

This component delivers refrigerant pressure monitoring & compressor protection interlock logic control. The refrigerant pressure monitoring & compressor protection interlock logic control continuously detects refrigerant pressure value of chiller circuit. The refrigerant pressure monitoring & compressor protection interlock logic control cuts off compressor start command once pressure exceeds high limit or drops below low limit. The refrigerant pressure monitoring & compressor protection interlock logic control sends fault alarm signal to vessel monitoring panel when abnormal pressure is captured. The refrigerant pressure monitoring & compressor protection interlock logic control provides hardware interlock protection independent of main controller.

This DAIKIN spare is an essential marine chiller refrigeration protection spare for vessel air conditioning cabinet overhaul. The marine chiller refrigeration protection spare can replace faulty 2222611 pressure switches directly. The marine chiller refrigeration protection spare meets IEC and marine classification safety specifications. The marine chiller refrigeration protection spare is widely fitted on cargo ships, tankers and offshore platform Daikin chiller systems.

DAIKIN 2222611 pressure switch safeguards chiller compressor against abnormal refrigerant pressure. It executes hardware protection interlock and fault alarm output, performing reliably under high humidity and salt spray marine machinery room environments.
