Tunnel Trays

The tunnels of our tunnel trays can be arranged parallel or crosswise to the flow direction. Trays with tunnels crosswise to the flow direction provide long residence times. An increase of the residence time in processes with risk of solids deposition can be realised with both constructions.

Tunnel trays can be manufactured out of metal or plastic.

Owing to the self-sealing cartridge construction, minimal liquid loads (approx. 0.02m3 / m2h) can be handled at medium gas loads. The trays can be equipped as well with deentrainment devices.

  • suitable for lowest liquid loads
  • liquid-tight
  • preferred type for application in acid recovery
