Laboratory High-Temperature Muffle furnaces are available in 900°C, 1100°C, 1450°C, 1700°C, 1800 °C
Laboratory Muffle furnace is a closed chamber laboratory instrument used for heating at high-temperature ranges from 50°C to 1800°C. Zirconia Fiber Board/Alumina Bricks gives an advantage to the high-temperature furnace chamber. We call it box furnace because of its design and shape & Muffle furnace because of its working without noise. We are the leading manufacturer of high-Quality Muffle furnace in India. Yatherm offers a wide range of muffle furnaces starting from 900 degrees Celsius to 1800 degrees Celsius.
This machine is controlled by a programmable controller and has features of RAMP RATE & SOAKING TIME. We can use SSR or SCR or Thyristor or Transformer for electric supply from source to heaters. Different temperature range furnaces use different types of heaters to achieve the maximum temperature with the help of different types of Thermocouple range from K type, R type to B type. Yatherm is a known brand in the field of 1800 degree muffles furnace with a working temperature of 1800 degrees with the help of high-quality graphite heating rods.
Muffle furnace Construction
High Temperature Muffle furnace/Muffle Oven designed in triple walled structure for long life and low skin temperature. Our Furnace comes with the insulation of the 1400 ZTL fiberboard for No Skin Temperature. We customized a box furnace with 5-7 inches of insulation in all sides to avoid heat loss and low skin temperature for user safety. Yatherm furnaces come in SS 304/PCRC sheet with rugged construction & high-quality lockable wheels for better performance & long life.
- Heating Element: Silicon carbide(SIC) heating ROD, molybdenum Disilicide (MoSi2) U shape rod & Kanthal A1 wires according to the temperature. These are few real images of heating elements used in a muffle furnace.
- Temperature Control: Microprocessor based profile PID controller gives accurate and programmable temperature setting with SV and PV display.
- Chamber construction: Muffle furnace has triple walled construction and equipped with zirconia fiberboard cemented from all sides for long life. Given the below images explains how we manufacture the chamber of a muffle furnace. Chamber construction plays an important role in the working of a furnace by keeping it cool from outside for the safety of the user. We provide 7 inches insulation from all sides for the zero skin temperature of a Laboratory muffle furnace.
- Temperature Range: Room temperature to 900°C, 1100°C, 1450°C, 1700°C, 1800°C. Choosing a furnace according to your requirement depends on the temperature range. All Muffle furnaces are designed with different working temperature and maximum temperature range.
- Voltage: To work on 220/230 V A.C. supply., big size comes in three phase 440 V, A.C.
- Doors: Our laboratory Muffle Furnaces are equipped with insulated doors with board insulation. There is no heating on the door due to good quality insulation. Yatherm Muffle furnace doors are supplied with hinges and door lock.

High-Temperature Muffle furnace working principle
It has mainly three parts; electronic control unit, the inner chamber and insulation & most importantly furnace chamber is heated by electric resistance elements. Door Safety Switch to disconnect the power supply of heaters for saving the heating elements and chamber from thermal Shock. The microprocessor PID controller controls the supply of the heaters and gives a reading in the LED display.

ATMOSPHERIC MUFFLE FURNACE
We are manufacturing Atmospheric muffle furnace with vacuum facility inside the chamber. Yatherm manufactures atmospheric muffle furnace in temperature range of 200 degree Celsius to 1800 Degree celsius.
Atmospheric Furnace is a kind of Muffle furnace designed to work under inert atmosphere. Atmospheric furnace has a standard procedure of working. After switching on the machine we vacuum the chamber with the help of vacuum pump and vacuum gauge provided with the machine. Atmospheric Furnaces are designed to work in Nitrogen & Argon atmosphere. After vacuuming we purge the nitrogen gas inside the chamber for creating the inert atmosphere. Inert atmosphere is generally created to save the testing sample from Oxidation. After gas purging we start heating the furnace to our desired temperature. Yatherm offers Atmospheric Muffle furnace at economic price in INDIA.
