LABORATORY MUFFLE FURNACE

A muffle furnace is a high-temperature heating device used in laboratories and industries for ashing, heat treatment, and material testing. Leading muffle furnace manufacturers like WEIBER offer customized models with insulated chambers that ensure even temperature distribution and protect samples from direct heat exposure.

ACMAS Technologies Pvt. Ltd., under its WEIBER brand, is a renowned name among Muffle Furnace Manufacturers, Suppliers, and Exporters in India. We specialize in delivering Customized Muffle Furnaces engineered for precision, durability, and consistent performance in both laboratory and industrial environments.

Our Muffle Furnaces are designed to create highly controlled high-temperature environments up to 1800°C, ideal for critical applications like material testing, heat treatment, and ashing procedures. Each unit features an isolated muffle chamber that prevents direct exposure of the samples to the heating elements, ensuring uniform temperature distribution and protecting sensitive materials from contamination or thermal shock.

Built with advanced insulation and robust construction, WEIBER muffle furnaces offer energy efficiency, quick heat-up time, and long operational life. Whether you require a general-purpose laboratory muffle furnace or a customized muffle furnaces tailored to specific industrial needs, our equipment is trusted across research labs, academic institutions, textile and rubber industries, metallurgy facilities, and more.

As leading Muffle Furnace Manufacturers in India, we proudly serve a global clientele, offering reliable export services to regions including South Asia, the Middle East, Africa, and Europe. Each furnace is manufactured in compliance with international safety and performance standards, making WEIBER a trusted choice for high-precision thermal processing equipment.

    WEIBER's Laboratory Muffle Furnaces are Light weight with ceramic wool insulation (instead of Brick insulation). The outer casting is made of double walled thick PCRC sheet, duly painted with attractive stove enamel. The inner casing is made of alumina block/ceramic wall (as per temperature).The unit is provided with single doors (flap type, lift type, single side opening). This door is provided with magnetic door closer. This door is provided with lock and key arrangement.

    Heating:

    Heating elements are made of kanthal wire, silicon carbide rod, and molybdenum silicide rod depending upon the temperature.

    Temperature Control:

    The temperature inside our muffle furnaceis controlled through PID controller

    Temperature Range:

    Temperature range of our standard furnace is 900°C-1800°C.

    Voltage:

    To work on 220/230V A.C. supply.

    It have mainly three parts; electronic control unit, inner chamber and insulation. The furnace chamber is heated by electric resistance elements and is insulated with ceramic fiber insulation. The controller is located under the furnace chamber and is well insulated from the heat generated in the furnace chamber. A door safety switch removes power to the heating elements whenever the furnace door is opened. The temperature is controlled by one of three types of controllers
