Harper’s expertise in high temperature furnaces is focused on continuous processing at temperatures of 500 to 3000°C and in controlled atmospheres for a range of advanced materials. We don’t shoehorn a standard line of products to fit our customers’ requirements. We use our building blocks to deliver the ideal furnaces, calciners, and kilns for every customer’s unique process needs.
The design of a Harper furnace begins with understanding the customer’s goals and utilizing our exceptionally skilled engineering team to analyze their distinct process requirements. Harper works to devise a complete thermal solution with our range of offerings including gas treatment and handling and fully integrated control systems. Our depth and breadth of engineering experience allows us to develop the optimum thermal processing system for gas-solid or solid-solid reactions.
We consider ourselves process experts in advanced processes including calcination, graphitization, carburization, controlled oxidation, reduction, purification, pyrolysis, drying, metalizing, debinding, waste remediation, and more. Precise control of temperature, process atmosphere, material flow, and residence time ensure consistent and uniform material production in our high temperature furnaces. Harper’s systems also address solutions for those materials where oxidation is a concern by incorporating revolutionary design features. Harper offers extraordinary patented gas-tight designs and superior sealing system with unique purge chambers. Additionally, because of the high temperatures associated with Harper furnaces, we are experts in ensuring our equipment is exceptionally energy efficient. We focus on incorporating materials and design features in our high temperature furnaces that result in the conservation of energy, cooling water, and protective atmospheres.
