The SD-MRP-2000 is a pull regulator (negative pressure regulator) that regulates the negative pressure in the fireplace of a self-draught boiler.
The system consists of a differential pressure regulator and a relay box used in combination with a damper regulator type MS-35M4-SR.
The system is designed to replace older drag regulators type SD/SD-D with a minimum of changes in the existing installation.
The traction regulator regulates the negative pressure (draught) of self-draught boilers to a constant low value during the burner operation. This means that the burner burns independently of tensile variations and leakage air. The burner's maximum combustion performance can be utilized throughout the year, resulting in high fuel efficiency
