Box / Chamber Furnace - BF/CF
Introduction
The box furnace is a versatile, box sized industrial furnace, an essential thermal processing equipment for heat treatment applications. Tempsens box type furnace consists of heating elements located at the sides of the heating chamber which ensures a better thermal uniformity. Our box furnace is manufactured according to the needs of modern industries using refractory bricks or lightweight ceramic fiber board insulation which are capable of reaching temperatures from 900°C to 1800°C. The furnace control box manages PID controller and data logging software which is essential for regulating temperature throughout the heating cycle which is ideal for sintering high-temperature materials, glass melting, ceramic testing, fusion processes, and powder metallurgy applications.

About Box / Chamber Furnace - BF/CF
Furnace Construction & Heating Chamber Design
The chamber furnace features a heavy insulated rectangular chamber with a front opening door which can be hinge type or vertical lift depending on the chamber size. Tempsens box type furnace is equipped with heating elements placed along the sides of the heating chamber which are manufactured using refractory bricks based construction or lightweight ceramic fiber board insulation.

Tempsens box furnace has NABL approved thermocouples to ensure measurement accuracy and compliance with regulatory requirements. The safety features of the furnace include an overheat protection controller, microprocessor controlled temperature management system, door limit switch, and automatic shutdown; these features work together to ensure the furnace operates safely, and meets all standards for industry compliance.
Yes. Tempsens is a box furnace manufacturer that allows for several different customization options, including gas purging for Ar, N2, O2, H2, CO etc. The ability to integrate a vacuum pump for heat treatment. It also has the option to use programmable PID controllers with RS232/RS-485/Ethernet data logging, and custom internal dimensions.
The industrial box furnace maintains uniform heating with the help of heating elements which are positioned on the sides of the furnace chamber. Microprocessor-based PID controllers continuously monitor and adjust power output via thyristor or SSR units. NABL-certified thermocouples offer precise temperature feedback to eliminate hot spots and thermal gradients inside the heating chamber.
Temperature capability for box furnaces: 900 – 1800°C based on type of heating element. NiCr elements are used in the CF-900 and the CF-1600 and CF-1800 use MoSi₂ elements. The broad temperature range is ideal for many different applications, from simple heat treatment processes to more advanced sintering of materials and glass melting.
Tempsens box furnace is equipped with either refractory brick or lightweight ceramic fiber board insulation. The heating elements are positioned on chamber sides ensuring uniform temperature distribution. For temperatures up to 1600°C & 1800°C, MoSi₂ elements are used, while lower models utilize FeCrAl or SiC elements.
