Tandem seal is Grundfos’ name for a shaft seal system, where an additional sealing chamber has been mounted on the existing shaft seal.
The primary unit of temperature is degrees Celsius. However, temperature can also be specified in other units, such as Fahrenheit [°F] and Kelvin [K]
Temperature control mode is used in circulating systems without control valves to generate a variable flow and in systems where it is important to have a constant temperature
Temperature sensors are used in all kinds of building installations within ventilation, heating, air conditioning, etc.
A temperature transmitter is used to transmit the measured temperature as an analogue signal to a receiver.
A thermostat is a device for regulating the temperature of a system so that the systems temperature is maintained near a desired set point temperature.
A thermostatic radiator valve is fitted on radiators and convectors to regulate room temperature. The valve functions automatically and is comprised of two parts: a sensing element and a valve casing.
A thermostatic return temperature limiting valve is installed in a system when the return pipe water temperature must not exceed a set temperature.
A two-string system, where each radiator on the same floor has the same total distribution pipe length is called a Tichelmann system.
TUV is an abbreviation for Technischer Überwachungsverein – an independent state-registered testing agency.
