By choosing Akvilon Renofast, you get a reliable stainless steel chimney lining system with CE certification, designed for long service life and full compliance with EN 1856-1.

Renofast single-wall chimney pipes are intended for renovation and modernization of existing brick chimneys and air ducts in residential, public, and industrial buildings.

They improve chimney draft, prevent damaging effects of condensation and combustion products on chimney inner walls, and ensure safe and efficient flue gas exhaust from various heating devices — such as, stoves, fireplaces, boilers, etc.

The shape of the chimney pipe is crucial for system efficiency and installation convenience.

• Round Pipes: Provide optimal draft and uniform flue gas flow with minimal turbulence. They are ideal for new chimney systems, connecting heating boilers, and inserting into large existing brick flues. Round shape is most effective for smoke exhaust and reducing soot buildup.
• Oval (Elliptical) Pipes: Particularly suited for renovating brick chimneys, as they better fill rectangular flue sections, reduce gaps, and increase cross-sectional area. This improves draft and reduces the negative impact of condensation.
• Custom Shapes and Configurations: Used when adapting to complex shaft shapes or specific connection requirements. We offer tailored solutions based on your project needs.

These sizes are optimized to maximize the usable volume of brick flues and ensure perfect compatibility with standard shafts:

Optimal Fit:

• 220×115 mm profile fits channels sized 250–270×140 mm (so-called "½ × 1 brick"). Ideal for equipment with D-180 or D-160 mm outlets.
• 180×115 mm profile suits 200×140 mm shafts ("½ × ¾ brick") and compatible with devices with D-150 or D-130 mm outlets.

In both cases, a 20–25 mm clearance on each side is maintained, preserving over 90% of the original chimney cross-sectional area.

Efficiency and Ease of Installation:

• Precise fit ensures good draft and prevents turbulence or constriction.
• Free clearance allows fast and easy installation without obstacles.

Both sizes are compatible with most brick shafts in private and multi-family homes, so we always keep them in stock for quick order fulfillment.

Custom Sizes Available Upon Request:

We also manufacture non-standard pipes according to your drawings or technical requirements to meet specific project needs.

Yes, we are the direct manufacturer. All our products are certified to high European quality and safety standards and carry mandatory CE marking confirming compliance with EN 1856-1.

Our complete production cycle — from design to finished product — is carried out at our factory in Riga. We ensure impeccable quality at every stage using precise laser cutting, automatic rolling, and robotic welding. Each element undergoes strict quality control.

Having our own warehouse allows us to maintain stock and promptly fulfill orders with minimal delivery times.

We offer several material options to meet different operating conditions and budgets:

• Budget Series: Made of AISI 430 stainless steel — suitable for environments with moderate humidity and condensation. Recommended operating temperature up to 600°C.
• Standard Series: Made of heat-resistant AISI 304L stainless steel with 0.6 mm wall thickness. It offers high corrosion resistance and withstands temperatures up to 850°C.
• Premium Series: Designed for the most demanding and aggressive environments. Made of AISI 316L steel with increased wall thickness up to 1 mm — providing maximum durability and mechanical strength.

Operating Temperature:

• AISI 430: up to 600°C
• AISI 304L: up to 850°C

Pressure Mode:

• Natural draft systems operate effectively without additional sealing.
• For overpressure systems (e.g., modern gas boilers), the following are required:          
  • Heat-resistant silicone seals
  • Special high-resistance sealants
  • Class D tightness, which ensures reliable operation under increased pressure
