About Lab and Process Furnace
Tempsens Laboratory and Process Furnaces are electric heating devices used in laboratory and industrial processes that require an accurate and controlled thermal environment. Our manufacturing methods have resulted in robustly constructed furnaces using high-quality materials such as steel and ceramic, making them ideal for both scientific and industrial applications. The available designs range from 4 litres to 40,000 litres in capacity, and temperature ranges from 50°C to 3000°C provide the uniformity and repeatability required for critical applications.
What Is a Lab and Process Furnace?
Laboratory furnaces are devices designed to heat materials or to heat-treat them to improve durability. Process furnaces are similar devices but are much larger than laboratory furnaces and are intended for large-scale thermal processing operations. Both types of furnaces operate on the same principle as electric kilns or other electric heating units. In both cases, electrical energy from the AC power supply is converted into heat via heating elements, producing a constant and contaminant-free heating environment.

FAQ
Frequently Asked Questions
Find answers to frequently asked questions related to Lab and Process Furnace.
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.
Yes, definitely. Tempsens can provide customized bottom loading furnaces that can be configured to fit your particular industrial application. Some of the options TempSens may include are: Gas/vacuum purging, Datalogging Software, and Ethernet connectivity.
Yes, because of the insulated work platform and the DC motor lift mechanism that provides stability to the work platform throughout the programmed temperature range, there will be very little variation in temperature throughout the cycle.
The industrial bottom-loading furnace utilizes high-efficiency heating elements (SiC, FeCrAl, MoSi2) at operating temperatures of 1200C, 1400C, and 1800C, which are configured for these temperature profiles. The BLF-I can also produce a heated load cycle.
Bottom loading contributes to temperature uniformity by providing strategically placed heating elements, multiple layers of insulation that allow for diffuse thermal distribution and no thermal gradient that would adversely affect material quality.
Bottom loading reduces the amount of vibration experienced during material handling; making it the best approach to handling brittle ceramics and delicate glass components that need as little mechanical disturbance as possible.
Main types of furnace include muffle furnaces, high-temperature furnaces, tubular furnaces, bottom loading furnaces, vacuum furnaces, electric ovens, annealing furnaces, chamber furnaces, bogie hearth furnaces, and microwave furnaces for diverse laboratory and industrial applications.
Industrial process furnaces (for example) are large-volume production-furnaces designed for high-volume production (up to 40,000 liters) and automatically control the amount of gas and or electric heat that runs through the furnace while laboratory or research & testing based furnaces, are small precision instruments used for research, test results, and testing of small batches materials with very specific temperature-control parameters.
Tempsens offers furnaces covering a wide range of temperature requirements, including laboratory furnaces (500°C–3000°C), industrial furnaces (250°C–3000°C), laboratory and industrial ovens (50°C–500°C), and microwave furnaces (250°C–3000°C), depending on the heating element and application requirements.
