Furnace Technologies

Harper’s capabilities in high temperature furnace technologies are focused on continuous processing at high temperatures 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 first-of-a-kind furnaces, calciners, and kilns for every customer’s unique needs.

High Temperature FurnaceThe design of a custom Harper furnace begins with understanding the customer’s goals and utilizing our exceptional 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 range of experience and engineering expertise allows us to develop the optimum thermal processing system for gas-solid or solid-solid reactions. We consider ourselves process experts in advanced processes up to 3000°C, 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.

Harper’s furnaces also address solutions for those materials where oxidation is a concern with revolutionary design considerations. 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 that result in the conservation of energy, cooling water, and protective atmospheres.
