Roth thermal decoupler

Roth HygieneXtra for perfect drinking water

Heat transfer at mixing valves - no thanks

Within the Roth drinking water system, the Roth thermal decoupler represents another important component for compliance with the normative requirements and hygienic safety. It prevents the transfer of heat from the hot drinking water to the tap fitting and the subsequent heat conduction to the cold drinking water. Thermal separation is important for surface-mounted tapping fittings in drinking water installations with integration of the hot water connection (PWH) into the circulation. The Roth thermal decoupler meets the requirements of DIN 1988-200. This stipulates that the maximum temperature of the cold drinking water must not exceed 25 °C.

The components

The pre-assembled component for connecting the hot drinking water consists of the individual components Roth wall disk, Roth Alu-Laserplus system pipe and Roth heat and sound insulation box thermal decoupler. The Roth plastic fitting as a T-piece is selected as a separate component up to dimension
20 mm as required. The Roth thermal and sound insulation box thermal decoupler made of expanded polypropylene (EPP) provides the necessary thermal and sound insulation.

Roth U-wall panels, which are also available with heat and sound insulation boxes made of EPP, are suitable for connecting the cold drinking water. The insulation thickness of the heat and sound insulation boxes meets the requirements of the EnEV and DIN 1988-200.
