Akvilon stainless steel chimney systems — a reliable solution for residential and industrial applications
SIA Akvilon — a Latvian manufacturer with over 20 years of experience in designing and producing stainless steel chimney systems. We supply certified stainless steel chimney solutions suitable for all types of heating equipment: boilers, fireplaces, stoves, saunas, diesel generators, and industrial installations. Production takes place at our own facility in Riga, using advanced technologies such as laser cutting, automated rolling, and robotic welding. This ensures high precision, reliability, and durability of every component. We offer both standard solutions and custom-made systems based on individual designs.
SIA Akvilon is not just a manufacturer but a provider of comprehensive solutions: we take into account technical requirements, operating conditions, and the specific needs of each project.
Page Overview
Single-Wall Chimneys RENOFAST — reliable solutions for chimney relining
Single-wall chimneys RENOFAST are designed for relining brick chimneys by inserting a steel pipe into an existing brick flue. The metal liner improves draft and reduces the exposure time of harmful substances — this lowers the risk of damage to the chimney’s inner walls and extends the overall system lifespan. We manufacture both round and oval (elliptical) liners specially developed for efficient modernization of existing flues to connect heating appliances such as fireplaces and stoves. Main sizes: 180×115 mm and 220×115 mm cover over 90% of standard chimneys. RENOFAST is suitable for various fuel types — natural gas, diesel fuel, wood, and other solid fuels, with flue gas temperatures up to 450°C (short-term up to 600°C).
Insulated Chimneys IZOKOMPAKT — three-layer sandwich systems
IZOKOMPAKT sandwich chimneys are three-layer chimney systems with 50 mm thick basalt wool insulation, designed for temperatures up to 600°C. These sandwich chimneys are ideal for private homes and industrial facilities, including systems with forced draft and excess pressure. The inner pipe is made of stainless steel with thickness starting from 0.6 mm. The outer casing is made from stainless, galvanized, or painted steel. There is an option to apply a high-quality powder coating in various colors — not only providing an attractive appearance but also ensuring a flawless finish without defects or fine scratches that can occur with pre-painted steel sheets.
Insulated Chimneys NordicPipe — premium system with powder coating
Insulated Chimneys NordicPipe is a premium-class modular system made of high-quality stainless steel 304L/316L with inner pipe wall thickness ranging from 0.6 to 1 mm. The outer casing is made of galvanized steel (DX51+Z275, 0.5 mm) with a longitudinal welded seam and coated with matte black powder paint, providing an attractive appearance and reliable protection against external influences. The system complies with EN 1856-1:2009 standard and has a CE certificate. The design allows for a simple "one-to-one" connection with expansion for a hermetic installation. The insulation is 50 mm thick basalt wool with a density of 100 kg/m³, ensuring high heat resistance up to 680°C. The temperature class ratings are T450 and T600, allowing use with equipment where flue gas temperature reaches 450°C (or temporarily up to 600°C).
The NordicPipe system is also suitable for custom solutions and can be adapted for specific tasks. This makes it an ideal choice for those seeking a reliable, safe, and durable chimney solution with a modern look.
Black Steel Chimneys
Black Steel Chimneys are designed for connecting solid fuel heating appliances — boilers, stoves, fireplaces — in private homes, industrial premises, and boiler rooms. These products are made from 2 mm thick black steel, resistant to high temperatures and aggressive flue gases. All components have a longitudinal seam welded using TIG technology, ensuring high strength, tightness, and durability of the system.
Easy and fast installation is achieved thanks to a "one-to-one" connection principle, which simplifies assembly and minimizes labor during installation. After welding, the products are cleaned and coated with heat-resistant Senotherm paint. It withstands temperatures up to +600 °C, does not emit smoke or odors, and protects the surface from corrosion, ensuring long service life and preserving an aesthetic appearance.
The products meet all European standards and carry the CE marking.
Chimneys for Pellet Boilers (SPNP)
SPNP black steel chimneys are specially designed for connecting pellet boilers and other pellet-fueled heating appliances. All pipes and fittings are made of cold-rolled carbon steel grade DC01 with a thickness of 1.2 mm, which ensures resistance to dry, low-temperature flue gases and provides durability and strength.
The longitudinal seam is TIG-welded, and the joints are equipped with heat-resistant silicone gaskets, ensuring the system's tightness and reliability. Installation is carried out in the direction of condensate flow, and the "one-to-one" connection design allows for quick and easy assembly without extra effort.
After welding and assembly at the factory, the components are coated with Senotherm heat-resistant paint, which withstands temperatures up to +600 °C, does not emit smoke or odors, and protects the surface from corrosion — ensuring a long service life and clean appearance.
The product complies with the European standard EN 1856-2 and bears the CE marking.
