Return temperature limiter RTL DN15, nickel-plated, Kvs 0.73, straight 9174-02.800

Return temperature limiter – precise control of thermal comfort

The RTL return temperature limiter is a reliable solution used in heating systems, both in radiator installations and underfloor heating. Its main task is to control the temperature of the heating medium, which translates into stable thermal comfort in rooms and optimized energy consumption. It is particularly useful in integrated systems where underfloor heating and traditional radiators work together.

Application and functionality

RTL effectively limits the return temperature, preventing overheating of rooms and ensuring even heat distribution. It can be used to maintain a constant temperature on smaller heating surfaces, up to approximately 15 m², making it an ideal solution for precise regulation in individual zones. This makes it possible to adjust the temperature to the individual preferences of users.

Construction and installation

The RTL limiter is characterized by its simple construction and ease of installation. Made of a nickel-plated body, it provides corrosion resistance and long-term reliability. It has an external thread Rp1/2, which allows it to be connected to threaded pipes or with appropriate fittings to copper, thin-walled steel and multilayer pipes (in the case of DN 15). Compact dimensions make installation easy even in tight spaces.

Performance and parameters

The RTL DN15 model with a Kvs coefficient of 0.73 ensures optimal flow of the heating medium while maintaining precise temperature control. The nickel-plated coating of the body and connecting fittings guarantees high corrosion resistance and long device life. The "THE" marking and flow direction arrow facilitate correct installation and identification of the device.
