The right furnace for the job

Electrical furnaces convert electricity to heat safely, cleanly and cost effectively. The types of labs that use electric furnaces range from dental labs to university labs to quality control labs. Accordingly, the needs of each laboratory can be very different. Important specifications to consider when searching for a laboratory furnace include the process temperature, control requirements, dimensions of sample and inner dimensions of chamber or tube and pressure range.


Electric furnaces are clean, safe, and better for our environment. Electric heat is efficient and clean. Furthermore, you can recycle your heating elements. Send your old elements to National Element Inc. for re-cycling, and re-melting and save energy for the future.
