Injector cooler unit is a closed loop system; the cooling system is a pressure system. The pressure depends on the setting press
working principle
The HFO have to heat up so the viscosity of the reduced, The media oil temperature is very high; temperature of injector is also high, so it needs the pump on cooler unit to cool the injector.
