Safeties In Refrigeration System Onboard Ship
> HP cut out: Trips the compressor if the pressure rises above the working level
> LP cutout: trips the compressor when the pressure goes below the working pressure
> Differential lube oil pressure cutout
> Relief Valve in the condenser

Must Read:> why back Pressure Valve in refrigeration system?
> Belt driven: which connects the motor to the compressor. Belt slips off if the compressor shaft does not rotate . Thus it protects the compressor.
> Cylinder head relief valve
> Cooling low water flow/ high temperature alarm
> Motor overload
> Drier: Absorbs any amount of moisture present in the refrigerant
> Unloader: It helps the compressor to start easily with no pressure in the cylinder so that the electric motors can start with low torque and low Amps.
> Capacity controller: In large type refrigeration systems, automation is provided to meet the varying refrigerating load
> Sensors-temperature and pressure: Senses the temperature and pressures in each stage
> Oil separator: Separates Oil and Refrigerant
