Harper International's trusted expertise in integrated process lines has allowed us to
become a world leader in systems for Carbon Fiber Processing. From research scale to full
production, we provide the most innovative technology to support the advancing needs
of the market.
We take a comprehensive view of material transport, designing systems that
ensure best functionality, maximized throughput, minimized scrap and consistent product quality.
Harper offers an assortment of feeding and material handling solutions, including creel
stations, winders, drive stands, and material conditioners such as combs, moisteners, spreader
bars, as well as a variety of roll designs. We aim to design technologies that integrate
seamlessly into the line and deliver desired technical and business objectives.
Harperengineers bring a wealth of experience in pre treatment and material conditioning, weather
in traditional or emerging methods, such as chemical, electrochemical, plasma, or gaseous
treatments. Our focus is thoughtful management of chemical preparation and minimization and
treatment of the effluent solutions from the conditioning.
Harper offers the most advanced oxidation oven technology available today. Our state of the art designs are available
for tow bands from 300 millimeters to greater than 4,000 millimeters, incorporating a multitude
of technological improvements to support the markets growing needs. Some of these design
improvements include superior atmospheric seals, continuous monitoring of supply, recirculation,
and exhaust flow rates, and an improved nozzle design. For the customer, this means faster
oxidation through elimination of the chimney effect, improved velocity, uniformity and
range, assurance of temperature uniformity at a variety of flow rates, and optimal control
of the reaction ultimately enhancing fiber quality. Harper considers all aspects of the
customer experience with our technology. Our ovens modular construction design sets us
apart from competition with a significant reduction in labor versus similar field ***
times for a full line system.
Harper is the industry standard for continuous furnace technologies,
starting with our world leading LT and HT furnaces. We set the bar even higher with
designs for the most robust Ultra High Temp furnaces available anywhere, rated to 3000
degrees Celsius for the production of high modulous Carbon Fiber.
Harper approaches gas treatment and handling with focus on managing emissions and treating off-gas in an environmentally
conscience manner. We also carefully consider opportunities for energy recovery for use
within the process, aimed at reduced operating expenses and garnering a competitive advantage.
From first point of engagement, Harper carefully designs a production plant with rigorous detail
and thoughtful consideration of how the facility will be operated. Our controls group develops
a sequence of operations that drives simultaneously toward efficiency and enhanced product quality.
Our integrated design connects all process equipment to one centralized control system,
ensuring operation is that of a cooperative plant all funtioning on the same control platform
rather than individual and isolated control platforms.
