Closed loop drying systems, which are very common with hopper
dryers in the plastics industry, operate at very low pressures of a few
inches of water. The air passing through the DewPro bypass is fed
back to the main stream after a pressure drop in the main line. In this
configuration, the DewPro bypass has no flow restriction at the inlet
and outlet.The outlet is equipped with a 6 mm (l/4") tube fitting to
allow simple connection of the loop tubing.
