Chimney liners are made of acid-resistant chrome-nickel stainless steel sheet (type 1.4404 according to DIN 17441) of thickness range from 0,5 to 1,0 mm. Their standard application is fume extraction from gas and oil fired heating devices, working in negative preassure conditions. These types of  chimneys are resistant to corrosion process caused by acid condensate, produced during burning process.

Advantages:

• acid-resistant, especially against sulphuric acid
• much lower resistance of fume flows in comparsion to traditional brick chimneys, because of small roughness of the surface
• possibility of applying chimney liners inside buildings, in lately built chimney duct, as well as during the renovation of the old ones
• simple mounting process, without the necessity of demolition works
• wide possibilities of system configuration
• wide range of products, possibility of making non-standard products

Usage

Heat resistant chimney liner system are single-walled chimney liners and ducts, made of heat resistant chrome-nickel steel sheet (type 1.4828 according to DIN 17441). They protect the inner surfaces of ceramic chimneys (exhausting fumes from wood burning stoves), from the destructive functioning of temperature and acids. These chimney liners can withstand high temperatures that can occur in woodburning appliances.

Advantages:

• high acid-resistantance
• much lower resistance of fume flows in comparsion to traditional brick chimneys, because of small roughness of the surface
• possibility of applying chimney liners inside buildings (renovation of old chimneys)
• simple mounting process, without the necessity of demolition works
• wide possibilities of system configuration
• wide range of products, possibility of making non-standard products

Usage

Flexible chimney liners are made with chrome-nickel strip 1.4404 of 0, 12mm thickness. They are used as a protection of chimney ducts extracting fumes from gas and oil heating devices working in negative pressure. To construct a SWKE system, rigid elements (of the SWK system) can be used, connected with the flexible pipe with the usage of special connectors.

Advantages:

• acid-resistant, especially against sulphuric acid
• possibility of applying chimney liners inside buildings, as renovation of the existing chimneys
• possibility of applying the chimney liner with uneven chimney ducts
• simple mounting process, without the necessity of demolition works

Usage

• to protect the inner surfaces of ceramic chimneys (exhausting wet fumes from oil and gas fired appliances)

Chimney connections are made of chrome-nickel heat-resistant steel sheet (type 1.4828 according to DIN 17441 ) of thickness 2,0 mm. Their application is fume extraction from stoves, where the fumes temperature can rise up even to 1200 °C.

Advantages:

• resistance to aggressive chemical compounds contained in the fumes
• long life span of the chimney, with the possibility of recycling all of the elements after usage
• exploiting the boiler to its maximum efficiency
• easy and simple mounting process, without the necessity of demolition works
• multiple system elements configuration possibilities
• non-flammable material and high tightness of the chimney

Usage

Chimney connection system is used for building chimney connections (connecting stove with chimney duct), it is made with mild steel sheet type DC01. It is recommended as a smoke extraction duct from solid fuels burning devices, where the temperature can rise up to 1000 ^oC. Pipe elements are welded with laser technology, that guarantees  highest connection quality, aesthetics and tightness.

 Advantages:

• easy and simple mounting process
• long working life
• avaliable in two colours: black (standard) and cast grey (for individual order)
• possibility of applying as a connectors to stoves fired with wide spectrum of solid fuels
• can not work as a chimney duct

Usage

Chimney connections are made with mild DC01 steel sheet (in thickness 1,2 [mm]) powder coated. They are used as a chimney connections for pellet stoves. In the bell connection special silicone seals are used, what makes the system airtight and, because of  that, possible to use in overpressure installations. Elements are powder coated with high temperature silicone coat (inside and outside). They are available in black color. Maximal temperature of constant work:  250°C.

Advantages:

• easy and simple mounting process
• high chimney tightness
• lower price than acid-resistant
• building chimney connections for pellets stoves
