    Why is my GESTRA UNA 38 Industrial Equipment blowing off live steam?

      Your GESTRA Industrial Equipment might be blowing off live steam because the control unit is damaged or worn, requiring replacement. Alternatively, dirt, precipitated solids, or foreign particles might have accumulated. Try operating the float-lifting lever if fitted, clean the pipes and all internal components. If the problem persists, consider replacing the internals or the entire equipment.

    What to do if fluid escapes (leaking) from GESTRA UNA 38?

      If fluid is escaping from your GESTRA Industrial Equipment, it could be due to several reasons. The body may be damaged by corrosion or erosion, necessitating replacement with a new unit made of suitable material. The equipment or the body itself might be damaged, also requiring a replacement. A damaged gasket could be the cause; replace it and clean the gasket seating surfaces. Lastly, the stuffing box packing might not be tight enough. Tighten it by hand, ensuring it doesn't impede the movement of the internals.

    How to improve the thermal output of GESTRA UNA 38?

      Harry CoxAug 23, 2025
      If your GESTRA Industrial Equipment has a low discharge capacity and insufficient thermal output, it could be due to several reasons. The equipment might be undersized, requiring you to use a model with a larger discharge capacity. The differential pressure could be too small; try increasing the steam pressure or lowering the pressure in the condensate line, or consider using equipment with a larger discharge capacity, a pump steam trap, or a condensate return unit. Insufficient deaeration may also be the issue; connect an additional air vent. Finally, ensure the pipes have a continuous fall in the flow direction.

    What to do if GESTRA UNA 38 discharge capacity is low and the equipment is cold?

      If your GESTRA Industrial Equipment has a low discharge capacity and feels cold or only warm, check if the shut-off valves for fluid flow are closed and fully open them. Also, the inlet, outlet, or the equipment itself could be dirty. If fitted, operate the float-lifting lever and clean the pipes and all internal components. If necessary, replace the internals or the entire equipment.

    Why is my GESTRA Industrial Equipment cold or only warm to the touch?

      Cindy MontgomerySep 3, 2025
      If your GESTRA Industrial Equipment is cold or only warm to the touch, it might be because the sealing plugs are still attached to the connections. Remove the equipment, remove the sealing plugs, and then remount the equipment.
