EW-Alkon – metal-sealing, single-walled stainless steel flue gas system, the innovative all-rounder
EW-Alkon is a universally applicable, single-walled flue gas system for connecting lines and space-saving shaft installation. The connection technology with metallic surface seal combines the quality of welded systems with the advantages of light and fast element construction.
The conical plug connection with the ideal taper angle of 2° ensures a pressure-tight connection and at the same time has a high self-locking effect against loosening. The metallic sealing principle without elastomer seals is consistently implemented right down to the cleaning caps and is patented throughout Europe.
Therefore, EW-Alkon can be used over the entire temperature range from condensing operation up to 600 °C continuous operation in both negative pressure and positive pressure up to 5000 Pa.
This suitability for all types of fireplaces, including CHP units, emergency power systems, fuel cells, engine systems, allows the heat generator to be converted at a later date or flue gas heat exchangers to be retrofitted, thus saving investment costs.
A wide variety of fireplaces can be connected, whether chimney or tiled stoves, boilers for oil, gas, wood, wood pellets or condensing boilers for oil or gas. The metallic sealing principle means wear-free operation, minimizes maintenance costs and increases the operational reliability of the heating system.
As a WPG design in material 1.4539 for wood logs, wood pellets and wood chips, the EW-Alkon system is approved for humid operation after any soot fire.
