  • Chamber roof cooling system minimises powder deposits (bearding) and prevents overheating of any deposits that do form
Swivel adjustable lances

Swivel adjustable lances

Swivel adjustable lances for improved safety

  • Easy and accurate process adjustments and enhanced operator safety through short lances and side-mounted placement
  • Each air distributor has integrated high-pressure nozzle assembly and optional fines return capability
  • Depending on required functional properties, fines separated from exhaust air can be reintroduced in the atomising zone

Spray monitoring system

Spray monitoring system

Spray monitoring system for full control

  • Continuously monitors spray pattern of high-pressure nozzles to ensure safe spray drying and prevent nozzle leakage or product build-up on nozzle tips
