Summary
Should I use a dedicated line or common line conveying system?
Choose dedicated lines when reliable operation matters most. Dedicated lines cost more initially and somewhat reduce throughput, but they help avoid line clogs. In a just-in-time system with small vacuum receivers, dedicated lines should be used to avoid overfilling. Where those conditions don’t apply, weigh the lower initial cost of a common-line system against its higher clog risk.
Dedicated or Common Line System
Choose carefully between a dedicated-line system and a common-line system. Dedicated lines cost more initially and somewhat reduce throughputs, but they help avoid line clogs and ensure more reliable operation. Dedicated lines should definitely be used in a “Just-In-Time” system with small vacuum receivers to avoid “overfilling.” See System Types
Frequently Asked Questions
Why use dedicated lines in a just-in-time conveying system?
In a just-in-time system with small vacuum receivers, the receivers can overfill. Dedicated lines should be used in these systems to avoid overfilling. Dedicated lines also help prevent line clogs and make operation more reliable, at a higher initial cost and with somewhat reduced throughput.

Greg Washburn is Vice President of Operations at Novatec and has been with the company for more than three decades. He is involved in all phases of engineering design and product manufacturing, giving him a broad perspective on how resin drying and conveying equipment moves from engineering concept through production and into real-world processing environments. Greg holds a B.S. in Mechanical Engineering from the University of Maryland, Baltimore County (UMBC) and an MBA from Loyola University Maryland. His experience spans engineering, manufacturing and operations across Novatec’s material-handling technologies.
Technology Manager, Novatec
Joshua Belisle is Technology Manager at Novatec, where his work focuses on simulation and technology development for resin drying. He earned a B.S. in Mechanical Engineering with a minor in Engineering Business from the University of Virginia in 2023 and joined Novatec that same year. Joshua uses simulation tools to investigate previously difficult-to-measure aspects of the drying process, helping Novatec better understand airflow, heat transfer and other variables that influence resin-drying performance.
