Return temperature limiter
Among other things, the return temperature limiter RTL is used to limit the return temperatures of radiators or combined floor/radiator systems to equalize the temperature of smaller floor surfaces (up to ca. 15 m2).
The return temperature limiter RTL is an automatic thermostatic controller. The temperature of the flowing medium is transferred to the sensor via conductivity. This keeps the specified value constant within a proportional band necessary for control. The valve only opens when the set limiting value has not been reached.
Sensor element with concealed upper and lower temperature range limiting or blocking of the settings using stop clips. Thermostat filled with an expansible medium. Overstroke safety. White cover with printed scale.
Valve body made of nickel-plated gunmetal (angle/straight). With stainless spindle and double O-ring seal. Outer O-ring can be replaced without draining the system.
Potential connections using the model with inside threading for threaded pipe or with compression fittings for copper, precision steel, or multi-layer pipe. For the model with outside thread, potential connection with additional compression fittings for plastic pipe.
For the RTL return temperature limiter use only the accompanying, labeled IMI Heimeier compression fittings (e.g. 15 THE).
Attention: The RTL return temperature limiter is constructed from a special valve body and sensor element. Thermostatic valve bodies cannot be used.
