Nitrogen Inert Loop

Nitrogen Inert loop is used in the Mini spray dryer and Nano spray dryer to handle organic solvents safely. Nitrogen Inner loop conserves resources and environment. For monitoring the oxygen percentage, special purpose oxygen analyzer with imported electro-chemical sensor is provided. Nitrogen inert loop is controlled through PLC control via RS485 port and safety interlocks for heater and feed pump also linked with PLC. Condensation system (-250c) consist of refrigeration compressor, pre-cooler, and condenser with solvent condensate drain system.


  • Nitrogen Inertloop enables spray dryer to work with organic solvents safely and prevent explosive conditions due to oxygen and pressure control.
  • This is explosion free spray drying due to inert gas atmosphere.
  • This is cost effective loop system which consumes low inert gas and recovers the organic solvents.
  • Fast installation and space saving.
  • It minimizes pollution and protects the environment and also protects instrument damage during process.
