Danfoss 067B3297 Thermostatic Element TEN 5

The Danfoss 067B3297 is a TEN 5 Thermostatic Element designed as a direct replacement or upgrade component for Danfoss thermostatic radiator valves (TRVs). Built to Danfoss’ exacting engineering standards, this element provides reliable, self-acting temperature regulation without the need for external power, making it an ideal solution for hydronic heating systems in residential and light commercial applications.

Product Overview

The TEN 5 thermostatic element operates on the principle of liquid-filled or wax-filled sensor technology, responding to changes in ambient room temperature to automatically modulate radiator valve flow. By maintaining consistent comfort levels room by room, it helps reduce energy consumption and improve overall system efficiency.
