Return temperature limiter RTL DX, angled version, DN15 36311222015

Return temperature limiter – precise control in your heating system

This angled return temperature limiter RTL DX, with a diameter of DN15, is a key component in underfloor heating and radiator systems. Its function is to protect against excessively high return water temperature, which translates to a longer lifespan of components and stable operation of the entire system. It is particularly useful in integrated systems, where underfloor heating and radiators operate in parallel.

The RTL limiter allows for precise temperature setting in the range of 10°C to 50°C, which enables optimization of thermal comfort and energy efficiency. Installation on the return loop of the underfloor heating is simple and intuitive, both for experienced installers and people performing renovation work independently. The valve body made of nickel-plated brass guarantees corrosion resistance and long-term reliability.

Application and functionality

The RTL DX return temperature limiter has a wide range of applications in:

• Underfloor heating: Protection against overheating of the heating loop, especially in systems integrated with radiators. Maintaining optimal temperature for user comfort and energy efficiency.
• Radiators: Limiting the return temperature to prevent damage to radiator elements and improve thermal comfort.
• Mixed systems: Ensuring stable operation of both underfloor heating (up to approx. 15 m² of surface) and traditional radiators.
• Installations powered from a single heat source: Controlling the temperature in different heating circuits, adapted to their specific needs.

Construction and characteristic features

The RTL DX valve is distinguished by its solid construction and high quality workmanship:

• Angled design: Allows for easy installation in tight spaces and aesthetic integration with the existing installation.
• Nickel-plated brass body: Provides corrosion resistance, mechanical strength and long-term reliability.
• Precise adjustment: The temperature setting range from 10°C to 50°C allows for accurate tuning of the heating system parameters.
• Clear setting scale: Facilitates quick and intuitive setting of the desired temperature. The white RAL9016 knob provides good visibility even in low light conditions.
• DN15 internal thread: Standard connection size facilitates integration with the existing hydraulic installation.
