Hot Zones

All refractory metal hot zones are manufactured on-site in our specialized sheet metal shop. We only use the highest quality metals sourced from our vetted US and European suppliers. Our qualified vendors machine our graphite hot zones to exacting specifications before final quality inspection at our facility. We manufacture hot zones for our own products and can provide replacements for other manufacturer’s furnaces as well. We also manufacture standard replacement hot zones with extremely competitive lead times to reduce downtime.


Experience, craftsmanship and high quality materials set our heat zone designs and applications apart from the competition. We are then able to provide our customers with original designs and manufacturing techniques which offer consistent performance. And our longevity in high-temperature vacuum furnaces gives us experience and insight to provide each of our systems with the most reliable, consistent service in the field. Plus, our sales team are well versed in hot zone component manufacturing used in our wide range of furnace systems. This is also true of all the sub-system components of our furnace systems. Our knowledge of these finer details provides a complete understanding of all replacement parts.
