Coaxial angle for exhausting condensate from the chimney, diameter 80/125 mm, 90°

A coaxial 90° elbow with a diameter of 80/125 mm is designed to change the direction of the flue system in a condensing boiler, providing ease of installation and adaptability to various installation conditions. The production process utilizes robotic technologies, ensuring high precision in connections and complete airtightness. After welding, the components undergo cleaning, anti-corrosion treatment, and thermal exposure at a temperature of 180°C, followed by painting in an automated chamber. This ensures resistance to moisture, acidic condensate, and external factors.

Functional Features and Purpose

The coaxial elbow is a crucial component of the exhaust gas removal system in condensing boilers. It connects the flue pipes to the boiler and allows for the adjustment of the flow direction of exhaust gases and air.

The design of a coaxial flue consists of two pipes of different diameters, one nested inside the other. The inner channel is responsible for venting low-temperature exhaust gases, while the outer channel supplies fresh air for combustion. In condensing systems, due to the low temperature of the exhaust gases, condensate forms inside the pipe, which is drained through a special drainage system.

Advantages of the Coaxial Elbow for Condensing Boilers

Resistance to Acidic Condensate – The inner pipes are made of corrosion-resistant materials (stainless steel or special plastic), preventing their degradation.

High Airtightness and Reliability – Heat-resistant seals prevent leaks of condensate and exhaust gases, extending the lifespan of the flue system.

Increased Boiler Efficiency – Preheating the combustion air reduces fuel consumption and increases the efficiency of the heating system.

Safe Operation – The outer pipe prevents overheating of surrounding surfaces, making installation possible in residential spaces, including wooden houses.

Installation Flexibility – Suitable for both horizontal and vertical installation, ensuring universal applicability.

Application of Coaxial Elbows in Condensing Systems

Coaxial flues are widely used in gas condensing boilers with closed combustion chambers. They ensure safe and efficient removal of exhaust gases and condensate. Such systems are suitable for both wall-mounted and floor-standing boiler models, creating energy-efficient operating conditions.

Thanks to its high reliability, durability, and ease of installation, the coaxial 90° elbow with a diameter of 80/125 mm is an optimal solution for adjusting the direction of the coaxial flue in condensing boiler systems.
