Paarth Auto Change Over Systems are designed to eliminate the necessary shutdown of Gas Systems or Processes while replacing empty gas cylinders.

Paarth Auto Change Over System uses Paarth Gas Regulators on each side of the cylinder line and discharge line. The two regulators on two lines of gas cylinders are set at slightly different delivery pressures for automatic disconnection of one side of the cylinder line and automatic opening of the other side of the cylinder line. The regulator on discharge line ensures constant delivery pressure to the systems under use or application areas.
