Low Temperature Circulator BCLT-203 3. The circulator is used for both external circulation and internal circulation. If it is used for internal circulation, plugs of water inlet and outlet must be tightened. If it is used for external circulation, remove the plugs, connect the water inlet and outlet with a tube, and fix a fastening throat hoop to ensure the tube ends are connected securely.
