A Look Inside The Furnace: Choosing the Best Hot Zone

One of Ipsen's furnaces, the TITAN T vacuum temper furnace, contains a metal hot zone with graphite elements for ease of replacement and uniform heating. When it comes to moly hot face shields backed by graphite felt, this used to be a fairly common design and is still provided.

Industrial Furnaces

Old design, hot zone graphite felt with graphite yarn sewn to stainless steel body, doors, etc. New design single or multi layered rigid graphite board fastened with CFC threaded rod and HLM nuts. For a harsh environment, add CFC plate on the hot-face to protect the rigid graphite board.

Vacuum Hardening Furnace: Horizontal Front Loading

Ultimate vacuum levels in the 10-6 torr range Modular hot zone design for easy maintenance All metal hot zones are available for ultra high vacuum processing – alternatively, economical graphite based insulation ensures extended durability Heating elements

Hot Zones

Vacuum Furnaces All refractory metal hot zones are manufactured on site in our specialized sheet metal shop using only the highest quality metals sourced from our vetted US and European suppliers. Our graphite hot zones are machined by our qualified vendors to exacting specifications before a final quality inspection at our facility.

Heating, ventilation, and air conditioning

Heating, ventilation, and air conditioning (HVAC) [1] is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality.HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics and heat transfer.

Vacuum furnace

Vacuum furnaces capable of temperatures above 1200 C are used in various industry sectors such as electronics, medical, crystal growth, energy and artificial gems. The processing of high temperature materials, both of metals and nonmetals, in a vacuum environment allows annealing, brazing, purification, sintering and other processes to take place in a controlled manner.

New energy efficient metallic hot zones for vacuum

In 80% of all vacuum furnaces, the insulation consists of solid graphite plates or graphite felt. Although this design saves energy, the employed material is a poor heat absorber and takes a long time to cool down. Furthermore, the presence of carbon in the

Vacuum Furnaces: Maximizing the Work Zone with Creative

2013/12/1Vacuum furnaces are expensive to purchase and operate. By using creative fixturing solutions, manufacturers and repair shops can safely increase the number of parts brazed or heat treated per run, increasing productivity while lowering the cost per unit. A shop can
