Muffle Furnace

Lab Muffle furnace consists essentially of a furnace designed and built for processes that require higher temperatures. Versatility in the use of this equipment adds functionality and tends to adapt to a variety of processes. With a superior thermal insulation system, the muffle furnace is shown very efficient with low energy consumption. Being Heat treatment equipment, a muffle furnace can be used in several areas of the industry. The Muffle furnace also called a chamber oven or box oven has a wide range of applications, including laboratory ones such as calcination and heat treatment.

A Muffle furnace or muffle oven is extremely important equipment in a laboratory for all kinds of heat treatment experiments. A muffle furnace is very similar to a greenhouse and is used, mainly in chemistry laboratories, when needed for very high temperatures in the calcination of substances. The muffle furnace consists of a metallic chamber, its coating being composed of refractory material.

At the same time, it is worth mentioning that, today, there are many models of muffle furnaces provided by Yatherm, that allow a temperature variation between 900 ° C to 1800 ° C. The Yatherm offers high-quality and high-temperature muffle furnaces and is available in the temperature ranges of 900 ° C, 1100 ° C, 1200 ° C, 1450 ° C, 1700 ° C, and 1800 ° C. Regarding the size of the chamber, a wide variety can be offered to suit each application.

STRUCTURE & DESIGN OF MUFFLE FURNACE

Regardless of size and operational range, all of Yatherm Scientific’s Muffle furnaces are of high quality and superior performance attributes that give the product an important market differential. Highlighted features are the carcass structure, built with a double wall; the use of thermal insulation based on the ceramic fiber of low density and high insulation capacity, the mechanical arrangement used for opening, and closing the door.

High-Temperature 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 on 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 Element used in 1450-degree Muffle furnace, molybdenum Disilicide (MoSi2) U shape rod used for 1800-degree Muffle furnace &  Kanthal A1 Spring type heaters used for 1100-degree Muffle furnace.
• Temperature Control: Microprocessor-based profile PID controller gives accurate and programmable temperature settings with SV and PV display. PLC with HMI can be used for data logging with a temperature-controlling system. The programmable controller displays the RAMP rate and soaking time together for better understanding.
• RAMP RATE: What is the Ramp rate in terms of furnace heating?  The ramp Rate is the Change of temperature per unit of time.  Like an 1100 degrees Celsius furnace, we offer 1 to 25 Degrees per Minute. Our furnace can achieve 700 to 800 °C with a Ramp rate of 20 to 25°C per minute and above 800°C it operates at a rate of 5 to 15°C per minute. Our Furnace Can achieve 1000 degrees Celsius in 45 to 90 Minutes.
• Chamber construction: The Muffle furnace has triple-walled construction and is equipped with zirconia fiberboard cemented from all sides for long life. Chamber construction plays an important role in the working of a furnace by keeping it cool from the outside for the safety of the user. We provide 7 inches of 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 requirements depends on the temperature range. All furnaces are designed with different working temperatures and maximum temperature ranges.
• Voltage: To work on 220/230 V A.C. supply., The big size comes in three phases 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 locks.

WHAT ARE THE BENEFITS OF A MUFFLE FURNACE?

The Yatherm Scientific Muffle furnace offers numerous advantages, such as; low proportional energy consumption, more efficient thermal insulation, more uniform heat distribution in the equipment, temperature, and process control, high performance and durability heating system, exhaust gases from the process, robust structure with greater durability, heating systems security, etc., versatile, robust and efficient equipment. The high level of resistance and the excellent results in terms of durability are factors that also call the consumer’s attention, as this set of benefits results in more practicality on a daily basis.

HOW DOES A HIGH-TEMPERATURE MUFFLE FURNACE WORK?

It has mainly three main parts; the 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 to save the heating elements and chamber from thermal Shock. The microprocessor PID controller controls the supply of the heaters and gives a reading on the LED display.
