SIKA water flow switch for Dometic marine chiller systems (MFG 290000172) — proves water flow and protects the compressor from no-flow lockout.
SKU / Ref: 290000172
This SIKA water flow switch (Dometic MFG 290000172) proves chilled/condenser water flow on marine chiller systems. It closes a contact when flow is present; a no-flow condition faults the control board and locks out the compressor to protect it. Installed at the chiller water outlet with the arrow aligned to flow direction; 3/4″ threaded connections.
