But don’t just take our word for it – read what real customers have to say about Harper…


“The Harper Pulse group’s outstanding performance on our recent HT Furnace upgrade and rebuild was key to a successful project that will deliver savings for our company’s bottom line.  Across our many experiences with Harper’s team, we have seen that they share the Cytec vision for safety and quality of work, along with an urgency to get production systems back in operation. With their strong technical and operational support, we completed the project ahead of schedule, below budget,  and reduced the total downtime for this equipment, ultimately delivering significant savings in capital expenses and an increase in revenue through additional uptime of the production line.”

“Harper’s ultra-high temperature (UHT) graphite furnace system has been rock solid in its performance. With the potential challenges a system that operates at 2500°C can offer, Harper’s design has been dependable, consistent and reliable since 2006. With minimal rebuild and operation at 2500°C, the system remarkably still has original heating elements and graphitic parts, which would normally degrade quickly at such high temperatures. The furnace is used for process development of multiple applications and it has proven versatile for this purpose.”

“It is critical that in our mission to develop breakthrough energy technologies, we have partners who are equally as dedicated to supporting us with innovative production equipment. We have been working with Harper since 2009 as we refined and optimized our thermal processing regime, and now that work culminates in this key piece of equipment that will enable our production scale operation.”

Phil Souza
Vice President of Manufacturing


“As we looked to significantly increase production capacity to meet the growing global demand for our unique and extremely wear-resistant Tough Coated Hard Powders (TCHP), we recognized that careful consideration and understanding of our thermal processing steps was required. Harper provided exceptional technical proficiency in this area, and then followed through with a tailored furnace that optimizes our process and delivers efficiencies in multiple areas.”
