The Ash Furnace is a high-temperature heating device widely used in various laboratories for multiple purposes including combustion, degassing, drying, sterilization, stabilization, sample ashing, and testing. The equipment has a rated power of 2.5 KW, an operating temperature range from ambient to 1000°C, a chamber size of 300×200×120 mm, a capacity of 7.2 liters, and a heat-up time of only 10-20 minutes. The furnace shell is made of high-quality steel plate by edge folding and welding, with a surface finish using imported two-color epoxy powder electrostatic spraying process, providing corrosion resistance and an attractive, durable appearance. The working chamber features a furnace hearth made of refractory material with heating elements positioned inside, and the space between the hearth and shell is built with high-quality insulation material for excellent thermal performance. The furnace body and intelligent controller are integrated into one unit, with a brand-new digital instrument for intelligent temperature control. Temperature uniformity is good, heating speed is fast, energy is effectively saved, and the service life of heating elements is significantly extended. The equipment has multiple protection functions for enhanced safety and reliability. It is widely used for sample preparation and analytical testing in industries including pulp and paper, chemical, pharmaceutical, environmental protection, and research institutions.
