Our furnaces/muffles can be constructed in sizes ranging from 3" - 60" (76.2 -1524 mm) in length and from 1/2" - 24" (12.7 - 609.6 mm) in diameter. Their solid metal housing is designed along with a ceramic fiber insulation in order to maintain an insulated environment. If a customer requires fast cool-down for an application, a perforated metal housing allows heat to escape quickly . On the other hand, if low pricing is paramount or an existing support mechanism is present, the furnace/muffle can be manufactured without any housing. Furnace/muffle entry styles include an open end, closed end, or vestibule end. A vestibule opening is designed to match another device, such as a bell jar entry used in semiconductor applications. Solar Products' furnaces/muffles can attain internal temperatures up to 1800°F (982°C) and are designed with watt densities ranging from 5 to 15 watts/in2 throughout their inner circumference. A furnace's watt density is often determined by a required internal temperature. Our furnaces/muffles can be controlled by a thermocouple extending through a thermowell hole that senses the internal operating temperature. Below are the design options from which you may choose.

 Industrial Furnace |
 Clamshell Style
This design makes use of a complete metal shell that is hinged along the furnace length in order to enable the furnace to be accessibly opened.
Solid Cylinder
The solid cylinder is the more common design. This furnace style can be manufactured with a metal housing for better structured integrity or with no housing to reduce cost.
