Custom Series 3350 High Temperature Box FurnaceKnown internationally for our ability to design and manufacture customized process heating solutions, here at Applied Test Systems (ATS) we are constantly working towards developing outstanding and efficient products. Our customers know that our reliable systems are built to last, supported by the skillful technicians in our service department.

Recently we designed and built a custom version of our standard Series 3350 High Temperature Box Furnace. Unique to this unit was the ability to hold an atmosphere – whether argon or nitrogen. The system was designed to purge the furnace of air and backfill with argon, which was delivered from a customer supplied argon tank. This design provided the customer an affordable way to operate the furnace without oxygen present, allowing them to avoid buying an additional vacuum furnace.

Capable of reaching temperatures up to 1700°C, this custom Series 3350 High Temperature Box Furnace was constructed from heavy gauge stainless steel with leveler mounts. A modified shell with water cooled seals was designed to contain the inert atmosphere, and a water manifold with valves provided independent control at each section of the furnace that requiring water cooling. Additional specifications and features included:
