Concealed PBTMV – Fixed Temperature

The FM Mattsson 5190 Pressure Balanced Thermostatic Bath or Shower Mixer with Fixed Temperature Knob is a top-tier solution for environments requiring consistent and safe water temperatures. Ideal for hospitals, nursing homes, child care centers, disabled and special care facilities, hydrotherapy facilities, hotels, and hairdressing salons, this mixer is designed to maintain a precise temperature within ±1°C, even during sudden pressure changes or temperature fluctuations in the pipework.

The mixer features a fixed temperature knob, preventing unauthorized adjustments and ensuring that the temperature remains stable and safe. Although this unit does not include flow control, it must be paired with flow control devices between the mixer and each outlet to ensure proper operation.

FM Mattsson’s exclusive Pressure Balancing Piston technology guarantees accurate and constant temperature control, while also providing additional protection against scalding. The unit is factory pre-set to 38°C, but it can be re-calibrated by a licensed plumber if necessary.

Built with safety in mind, the mixer includes check valves, line strainers, and a fail-safe system that prevents scalding in the event of a cold water supply failure. It operates efficiently within a pressure range of 50kPa to 1000kPa, with a recommended working pressure between 100kPa and 500kPa.

Manufactured in Sweden and WaterMark approved (Approval No. 1186), this mixer is backed by a 5-year warranty on the cartridge, ensuring long-lasting reliability and performance.
