Indicates the pressure in the polyol circuit.
14. Isocyanate heater sensor
Provides information on the temperature of the isocyanate heater.
15. Polyol heater sensor
Provides information on the temperature of the polyol heater.
16. Isocyanate intake filters
Prevent solid particles from the entering the unit’s isocyanate pump.
17. Polyol intake filters
Prevent solid particles from the entering the unit’s polyol pump.
18. Hydraulic pressure gauge
Indicates the pressure of the hydraulic circuit.
19. Isocyanate circuit safety pressure switch
Shuts off the solenoid valve in the event of excess pressure in the isocyanate circuit.
20. Polyol circuit safety pressure switch
Shuts off the solenoid valve in the event of excess pressure in the polyol circuit.
