JAWAR CERASTAL is an independent chimney system for exhaust of flue gases from heating devices run on any fuel.

Product description

The JAWAR CERASTAL chimney system consists of a set of pipes and fittings, the inner jacket of which is made of the modern JAWAR ceramics, produced in isostatic pressing technology, characterized by low water absorption, high tightness (2.5 cm muff) and very high resistance to high temperatures and their changes (thermal shock). The outer jacket is made of stainless steel, and the insulation is made of ceramic fibers.

The chimney system configured this way is an ideal solution for the exhaust of flue gas from devices fired with gas and oil, as well as with solid fuels, especially coal.

The JAWAR CERASTAL chimney system is the only alternative for the renovation of solid fuel fired boiler houses. Due to its construction, JAWAR CERASTAL is insensitive to aggressive exhaust gases, high temperatures and condensate.

Its durability and versatility exceeds all insulated steel systems currently used on the market. CERASTAL is covered by a 20-year guarantee for internal components made of JAWAR isostatic ceramics.
