The Horizontal Vacuum Furnace (HVF Series) is designed for horizontal front-loading applications. A standard horizontal furnace uses baskets or fixtured loads. The circular design hot zone delivers improved temperature uniformity and volume utilization.

The 3Q™ series of quick quench vacuum furnaces are available with 2-bar, 6-bar, and 10-bar cooling capabilities. This horizontal double-chamber furnace also includes a quench pressure range between 2-20 bar absolute. Gas quenching in a separate cooling chamber ensures superior metallurgical results. This process also eliminates deformation typically associated with workloads moving in a conventional two-chamber vacuum furnace. Additionally, with the hot zone away from the high-velocity gas cooling nozzles, there is less wear and tear on the hot zone which translates to lower maintenance costs and longer service life. The 3Q™ series features a larger gas cooling system with a post cooler heat exchanger that provides a lower gas quench temperature than any other gas cooling system in the market.

The Vertical Vacuum Furnace (VVF Series) is designed for vertical bottom loading applications. Like the horizontal vacuum furnace, vertical bottom loading vacuum furnaces utilize a circular design hot zone that provides for taller and larger workloads.

The Quantum Quench™ Vacuum Furnace offers controlled multi-directional delivery of cooling gas in selected quadrants without having moving parts inside the vacuum vessel. This patented design delivers controlled cooling in selected areas and eliminates maintenance commonly caused by moving parts within the main vacuum vessel which are constantly exposed to excessive heat. The circular hot zone and cooling arrangements are divided into four quadrants: the bottom quadrant below the hearth area, the top quadrant, and the right and left quadrants. Cooling gas can enter from any one quadrant or a combination of quadrants. An alternate cooling gas can flow from the top and bottom quadrants to control distortion and provide unparalleled metallurgical and physical results.

HIGH-PERFORMANCE, LONGER-LASTING HOT ZONES You’ve repaired, relined, and rebuilt your hot zone to extend its lifespan and performance for as long as you can. When this is no longer a practical fix, call on the hot zone experts at Nitrex to build a replacement hot zone for your existing vacuum furnace that is designed to deliver state-of-the-art performance and reduce operation and maintenance costs. Nitrex hot zones are the industry’s workhorses, designed to outperform competitive offerings with a lower cost of ownership. We can deliver a more durable, cost-effective, and thermally efficient alternative for even the most difficult processing applications. Click Here to download our Free Hot Zone leaflet
