Return temperature limiter RTL DN15, nickel-plated, Kvs 0.73, angled 9173-02.800

Return temperature limiter – precise control of thermal comfort

The RTL return temperature limiter is a reliable solution for controlling temperature in heating systems, both in radiator installations and underfloor heating. Made from high-quality materials and nickel-plated, the device provides long-term protection against corrosion and an aesthetic appearance. The DN15 model with a Kvs flow rate of 0.73 features an angular design that simplifies installation in tight spaces.

Application and functions

RTL is primarily a heating medium temperature regulator. Its main task is to limit the return temperature from radiators or maintain a constant temperature in underfloor heating systems with an area of up to approx. 15 m². This makes it possible to ensure optimal thermal comfort and efficient energy use. The valve automatically regulates the flow, working with Eclipse thermostatic valves, allowing precise adjustment of the installation parameters to individual needs.

Design and installation

The RTL valve consists of a solid nickel-plated body, a precise sensor and protection against excessive temperature jumps. The angular design simplifies integration with existing installations. Nickel-plating of the body and connecting fittings guarantees corrosion resistance and the durability of the device. Markings on the housing (THE, flow direction arrow, DN, II+) facilitate correct installation and identification of the valve. The possibility of using limiting clips allows for hidden limitation or locking of the valve setting.

For installers: The RTL valve is a proven component in IMI HEIMEIER systems, valued for its reliability and ease of integration with other heating installation elements. Precise temperature control translates into customer satisfaction and minimizes the risk of complaints related to the improper functioning of the heating system.
