Expired 2009, replaced by MS-35M4-SR
Description The SR-33 is a damper regulator that controls the flue gas damper on self-draught boilers.
Technical Data
- The damper regulator keeps the flue damper completely closed during the burner's standstill
- Before the burner can start, the damper regulator opens the flue damper completely and gives the starting state of the oil burner
- When the oil burner has lit, the flue throttle is controlled to an intermediate position where the negative pressure in the boiler is moderately large. In the case of a 2-step burner, the damper alternates between the setting for low 1 and the starting position depending on the boiler's heating
- The damper controller is prepared for completion of the towing control centre type SD-MRP-2000 \
