The extracite offered in the Heizprofi product range today is a hard-coal briquette of extremely high quality. Made according to the original formula and the traditional production process employed by the former SJ briquette factory in Hückelhoven, extracite is a quality leader among hard-coal products in Europe.
The basis for extracite is fine anthracite coal of a select quality which, mixed with a high-grade bonding agent, is pressed into the familiar cushion shape. And adorned as well, of course, with the traditional "S" and "J" marking. This, coupled with its compression strength, guarantees low-dust, loss-free handling and storage.
Its combustion properties are true to the historic original: high calorific value, low ash, absolute preservation of shape during combustion and slow burning are the outstanding features of this premium product, which is smokeless and odourless!
