33+ Years of Engineering Excellence Since 1992
High Temperature Engineering (Pty) Ltd was founded in 1992 by Giep van Eck, an industry visionary who recognised the highly specific material challenges facing precious metal refineries. From day one, our objective was clear: design and manufacture Fused Silica vessels that outperform standard market alternatives under extreme operating conditions.
Mr. van Eck remains actively involved in the organisation today, ensuring the foundational tenets of engineering excellence, hands-on quality control, and customer-centric innovation continue to govern everything we do.
For over three decades, we have operated at the forefront of the pyrometallurgical, precious metal refining, and casting industries — establishing HTE as an indispensable supply chain partner within the Southern Hemisphere and the global refining sector.
