Heavy-duty furnace for coal ashing with a temperature range up to 1100ºC. Meets ASTM D3174, D2361 and D2795. Features furnace chamber design which provides capacity for large number of crucibles and promotes faster combustion.

Features

• This single chamber model has a resistance wire wound refractory muffle, a digital programmable controller and a controller for over-temperature protection.
• The Digital Programmable Controller is a 8 segment system - any segment can be ramp or dwell - with dual display showing the measured value and set point or program status.
• Furnace has an outward and upward swinging door with a power isolation switch for protection of the operator when opened.
• A 50 mm ID chimney fitted to the chamber creates a natural draft, with air entering the rear and then being preheated before flowing through the front and over the samples. This design provides for very thorough ashing of all coal samples, regardless of their position in the furnace.
• Overall dimensions: 705 mm H x 505 W x 725 mm D. Chamber dimensions: 90 mm H x 170 mm W x 455 mm.
