Keith designs and builds standard and custom furnaces for processing a broad range of materials and products. 

Systems are available in laboratory to high-volume production sizes, with gas or electric heating systems, in batch or continuous processing configurations, and with many atmosphere and process control options. 

Our customers include leading aerospace, heat-treating, foundry, inorganic chemical, and specialty metals manufacturers worldwide. We combine the latest in control and automation technology with nearly 50 years of practical experience and industry leadership. 

The following overview of furnace capabilities describes many of the challenges Keith has successful solved. 

Advanced Materials

Homogeneous temperatures to 1800 C, integral drying and firing of saturated materials, uniform heat treatments of dense material, low tolerance for impurities, high volume organic volatization and venting, process repeatability, and resistance to chemical attack are some of the many process challenges Keith successfully solves.

Metals Processing

Keith provides special furnaces for uniform heat treatment of small or large metal parts, melting, holding, and transferring high volumes of non-ferrous metals, precise and repeatable solution heat-treating, and tightly controlled atmospheres. 

Specialty Metals

Precise management of multiple temperatures and process atmospheres, continuous removal of solvents, binders, and lubricants, extreme sensitivity to contamination or moisture, uniform heat treatment at high throughput, and tightly controlled rapid cooling are just a few examples of our expertise. 

Inorganic Chemicals

Keith offers solutions that combine precise control over all process parameters with greater operational flexibility to meet the increasingly complex requirements of the chemical process industries. Our systems are typically designed for longer heating cycles, resistance to chemical attack, low tolerance for impurities, and for applications where the residence-time-distribution is critical. 

Aerospace Materials

From space shuttle tile to stealth bomber technology to lightweight structural components for commercial aircraft, Keith works closely with leading aerospace and aircraft companies to provide novel solutions for high-performance challenges. 

Research & Development

Keith pioneered fast-firing 1700C laboratory furnaces in 1972. Today's Keith's FastHeat furnaces reflect nearly 30 years of innovation combined with input from leading universities and research facilities around the world. The rugged construction of these furnaces makes them ideal for small-scale production.
