"NOx"
"NOx" is used to refer to a group of nitrogen oxide (NO) and nitrogen dioxide (NO2) pollutants that are produced when fossil fuels are burned in a variety of processes including heating, transportation and industrial activities. NOx pollutes the air…
10-100 Base-T
10-100 Base-T is the designation for Ethernet connections that support data transfer rates of 10 Mbps (megabits per second) and 100 Mbps. Here is the meaning of this label: Data transfer rate: The number "10" in 10-100 Base-T indicates a data…
5G network
5G (short for 5th generation) is the fifth (latest in use) generation of mobile communication technology and mobile network, following 4G, launched in 2019. To take advantage of 5G, a device (e.g. smartphone, modem) capable of communicating on the…
A heating cable
A heating cable, also known as a heating cable, is an electrical cable designed to heat or defrost surfaces, especially in areas where ice, frost or snow accumulation may occur. These cables are used to maintain temperature in certain places such…
A heating rod
A heating rod is an electrical device used to generate heat. This element is often used in various heating devices, such as water heaters, radiators or dryers. Its main function is to transform electrical energy into heat, which is then transferred…
A non-programmable
A non-programmable thermostat or controller means that the thermostat can set one heating temperature based on a timer. But it cannot set different times on different days of the week. This is what programmable thermostats are for.
A pressure hose
A pressure hose is a flexible tube or hose that is used to transfer various liquids, gases or other media under pressure. Pressure hoses are usually made of a flexible material that allows them to adapt to the pressure and temperature of the…
A pressure station
A pressure station is a device used to control and maintain a constant pressure in a system, most often a water or hydraulic system. These stations are often used to ensure a consistent flow of liquid such as water, oil or other fluids in a variety…
A pressure switch
A pressure switch (also called a pressure sensor or pressure protection) is a device that is used to monitor and regulate the pressure in the system. Its main function is to switch the electrical circuit based on reaching a certain pressure. The…
A pressure vessel
A pressure vessel, also known as a pressure tank or pressure vessel, is a device used to store liquids or gas under pressure. These vessels play an important role in maintaining and regulating liquid or gas pressure in hydraulic and pneumatic…
A proportional dosing pump
A proportional dosing pump is a device used for accurate dosing of liquids with a certain proportion. This means that the amount of output fluid is controlled based on a certain ratio to the amount of input fluid. These pumps are structurally…
A semi-siphon
A semi-siphon is a variation of a regular siphon, which is used to remove waste water from sinks, showers or bathtubs in homes and other buildings. A polysiphon is also known as a polysiphon trap and is designed to prevent the return of unpleasant…
A sinusoidal output
A sinusoidal output is a type of output signal or a signal that takes the form of a sinusoidal waveform. A sinusoidal waveform is a mathematical form that has a curve shape similar to a sine function and is characterized by a periodic and smooth…
A socket with a pipe
A socket with a pipe seal is a special type of connecting component that serves to connect two pipe parts or pipes with an emphasis on the tightness of the connection. This socket has an integrated seal, often in the form of a rubber ring or…
A temperature class
A temperature class is a designation that determines the maximum temperature at which an electrical device, appliance or component can be safely used without risk of damage or fire hazard. The temperature class is especially important for…
A thermostatic head
A thermostatic head is a device that is used to regulate the temperature in radiators or heating elements in heating systems. Its main function is to maintain a constant temperature in the room and regulate the supply of hot water to the…
A thermostatic insert
A thermostatic insert is a component used in radiator heating systems to regulate the temperature in a room. This insert is installed in the radiator and enables automatic adjustment of the temperature radiated from the radiator into the room. Its…
A thermostatic mixing valve
A thermostatic mixing valve is a device that serves to maintain a constant temperature of water or other liquids when mixing hot and cold water. Its main function is to regulate the temperature of the outlet water to a preset value, which is…
A transformer
A transformer is an electrotechnical device that serves to decrease or increase the alternating voltage between two windings using electromagnetic induction. Its basic principle is the transfer of electrical energy from one circuit to another…
A ventilation unit
A ventilation unit, also known as a fan unit or an air handling unit, is a device that is used to exchange air between the interior of a building and the outside environment. It is an important component of air-conditioning systems, which ensures…
abbreviation DVGW
The abbreviation DVGW stands for "Deutscher Verein des Gas- und Wasserfaches e.V.", which translates as German Gas and Water Association. It is a German technical association that focuses on research, development and standardization in the field of…
abrasiveness
Abrasiveness or scratchiness is the abrasive, abrasive effect of a substance on objects coming into contact with it.
absorption
Absorption can be: in general and in medicine: absorption, absorption, amalgamationphysics and chemistry: the process of dissolving a gaseous compound in a liquid, or solid substancephysics:absorption of (light, X-ray, radioactive, etc.) radiation…
absorption surface
The absorption surface on solar collectors is the part of the collector surface that is responsible for absorbing solar radiation and converting it into heat. This surface is usually made of a material with high absorption capacity for solar…
accumulation tank
An accumulation tank is a device that serves to accumulate heat and then release it in heating or hot water heating systems. This tank is used to store the excess heat that is generated in the system when there is no need to use the heat at the…
