Train limiter 012 RaRo/012 RaRo E from Kutzner & Weber – precise draft control for exhaust systems

Product overview

The 012 RaRo draft regulator and its variant 012 RaRo E are components of air group 4 according to DIN 4795 for the reliable regulation of chimney draft. Both models offer high control accuracy, a self-acting and self-cleaning blade bearing, and a universal connection for easy flue pipe installation.

Key features

The devices are equipped with a robust turnbuckle for secure fastening and can be retrofitted to existing connecting pipes – regardless of their gradient. Cover segments allow for pipe diameters from 100 to 180 mm.

The design is geared towards long-lasting function and minimal maintenance: The self-cleaning blade bearing reduces deposits and ensures consistent control characteristics over long operating times.

Advantages for operators

A stable draft control improves combustion conditions in fireplaces, reduces fuel consumption, and thus lowers operating costs. At the same time, emissions are reduced, thereby decreasing environmental impact.

The simple retrofitting on existing lines makes the train limiter an economical solution for modernization and maintenance without costly conversion measures.

Installation and assembly

For installation, the universal connector is mounted onto the flue pipe, and the draft regulator is secured with the turnbuckle. The flexible design allows installation regardless of the slope of the connecting pipe.

Thanks to the cover segments, no special production is necessary for common pipe diameters between 100 and 180 mm, which reduces time and material costs during installation.

Technical data

Designed for Pipe diameter 100–180 mm by means of cover segments; corresponds to air group 4 according to DIN 4795. Mechanics and bearings are optimized for permanent function and precise control.

The unit is secured using a turnbuckle; a universal connector for flue pipe installation is included. Detailed dimensions and connection information can be found in the technical data sheet.

Maintenance and care

The self-cleaning blade bearing reduces maintenance requirements. Regular visual and functional checks as part of routine chimney maintenance are sufficient to ensure long-term, trouble-free operation.

Spare parts and services are available if required; maintenance intervals depend on the specific application and the operator's regulations.

Areas of application

The draft regulator is suitable for residential and commercial heating systems as well as industrial exhaust systems where a constant and controlled draft is required. Ideal for fluctuating external conditions such as wind and temperature changes.

The retrofit capability makes the product particularly suitable for modernizing older systems and for operators who want to improve the energy efficiency of their heating systems.

Manufacturing and quality

The train limiters are manufactured in Germany from high-quality materials and are subject to strict manufacturing standards. Precise manufacturing processes ensure durable and reliable components.

Compliance with relevant standards and high-quality workmanship ensure safe and efficient application in a wide variety of exhaust systems.

Scope of delivery and accessories

The scope of delivery includes the draft regulator including a universal connection piece for flue pipe mounting.Additional cover segments for adapting to different pipe diameters are included.

Optional accessories, spare parts, and technical documentation can be ordered separately; please contact your dealer or the manufacturer for this.
