  • Resources Resources

Atmospheric degassers aid in the prevention of potential blowouts and are engineered and manufactured to provide years of reliable service.

BRANDT™ DG-ATM degassers remove gas from the mud by accelerating the fluid through a submerged pump impeller and up a riser pipe, where the fluid sprays the baffle plate at the center of the spray tank, above the mud surface. The fluid is fanned out from the baffle plate with high velocity, creating a thin sheet that impacts the wall of the spray tank. Degassing occurs as the gas particles are brought to the mud surface by the high impact and turbulence of the thin spray sheet at the wall of the spray tank. The degassed fluid collects at the base of the spray tank and flows out of the discharge trough to the next pit. The gases escape through the top of the spray tank and dissipate into the atmosphere. This unit does not require an external feed pump.


  • Rugged, field-proven design enables reliable operation with minimal maintenance and downtime
  • Integrated feed pump ensures proper feed requirements with reduced component costs
  • Vertical-mount orientation allows installation in confined spaces
  • Variety of options available to meet different specifications
    • DG-ATM-6 is meant for use in standard mud tanks [6 to 8 ft (1.8 to 2.4 m) deep].
    • DG-ATM-8 is meant for use in deeper mud tanks [8 to 10 ft (2.4 to 3.0 m) deep].
