Freon

  Freon is a trivial designation of compounds from the group of halogen derivatives that contain at least 2 types of halogen substituents, one of which is fluorine (F). This is the unofficial name for a group of chemical compounds…

freon-free

The term "freon-free" is used to describe systems, products or technologies that do not contain freons or chlorofluorocarbons (CFCs). Freons are chemical compounds that were once widely used as refrigerants in a variety of applications, such as…

Frequency

Frequency is a physical quantity that expresses the number of repetitions or cycles of an event per unit of time. It is the rate at which an event or wave repeats itself in a time interval.   Frequency is measured in hertz (Hz), which…

Frequency

Frequency is a physical quantity that indicates the number of repetitions (oscillations, cycles) of some periodic event per unit of time. It is a basic parameter characterizing periodic processes, such as oscillations, waves and various types of…

frequency converter

A frequency converter is an electronic device that is used to regulate the frequency of the electric current, and thus also the speed of rotation of the asynchronous electric motor. Its main task is to change the frequency of the current, which has…

fuse

The fuse serves to protect electrical circuits from overload and short circuit. A fuse is a simple protective device that works on the basis of the physical principle of thermal or electromagnetic action. It is one of the most common protective…

Gabarrón

about company ELNUR s.a., based in Spain (Madrid), is one of the recognized world leaders in the field of electric heating equipment production. For more than 40 years, it has been providing solutions for modern comfortable electric heating…

Galvanic water treatment

Galvanic water treatment refers to the process of removing impurities and ions from water through electrochemical reactions. This process is similar to electroplating of metals, but in this case it is applied to water treatment instead of metal…

gas

A gas or a gaseous state or a gaseous substance is one of the basic states in which the individual particles of the substance are relatively far from each other, move freely in space and are affected by negligibly small attractive forces. In a…

Gas density

Gas density is a physical property that indicates the mass of a gas per unit volume. Basically, it expresses how much matter is contained in a unit volume of gas. The density of a gas is usually denoted by the symbol ρ (rho) and is measured in…

gasification boiler

A gasification boiler is a type of heating equipment that uses the process of gasification (conversion) of solid, liquid or gaseous fuel into fuel gas, which is then burned to produce heat. This type of boiler is usually designed to burn solid fuel…

gasoline

Gasoline is a liquid mixture of volatile hydrocarbons (mainly alkanes, cycloalkanes, aromatic hydrocarbons and alkenes) separated from crude oil and other additives (most often benzene and isooctane) that improve its properties as fuel. The usual…

Gauss

Gauss is a unit of magnetic induction field, which is part of the CGS (centimeter-gram-second) system of units. Magnetic induction, which is measured in Gauss units, indicates the strength and density of the magnetic field at a particular point in…

Gel batteries

Gel batteries are a type of lead-acid battery (or lead-acid battery) characterized by the fact that the electrolyte in the battery is in the form of a gel instead of liquid acid. These batteries are often referred to as "gel electrolyte batteries."…

Geminox

The manufacturer adheres to the Ecoefficiency motto, which actually means maximum efficiency, the lowest possible energy consumption and below-limit amount of harmful emissions with above-standard user comfort. The basis of success is the perfect…

Geothermal energy

Geothermal energy is a type of renewable energy that is obtained from the geothermal heat inside the Earth. This heat comes from the radioactive decay of elements in the Earth's crust and from the Earth's thermal radiation from its…

glass

Glass is a homogeneous amorphous, isotropic, transparent, solid and brittle substance in a metastable state, formed by cooling the melt. It mostly contains siliceous sand, soda, alkali metal oxides, limestone. It is a biologically inactive…

Glass ceramics

  Glass ceramics is a material that is created by combining glass and ceramics. This material is made by a process called "glass ceramization," where glass products are heated to a very high temperature and then quickly cooled. This…

Glass fibers

Glass fibers are thin and strong fibers made from a melt of glass materials. These fibers have exceptional properties and many different applications. Glass fibers are commonly used as reinforcement for various composite materials and products…

global warming

The generally accepted definition of global warming is the process of increasing the average temperature on the Earth's surface due to an increased concentration of greenhouse gases in the atmosphere. This process is considered to be the…

Glycol solutions

Glycol solutions are mixtures of water and organic compounds known as glycols. Glycols are hydrocarbons that have included hydroxyl groups (-OH) that allow the formation of aqueous solutions with high density and the ability to lower the…

Glycols

Glycols are organic compounds that belong to the group of sugars. They are carbohydrates with a relatively small number of carbon atoms and have a sweet taste. Glycols occur in several forms and can be simple or complex structures. Known examples…

Google Assistant

Google Assistant is a voice assistant developed by Google. It is an artificial intelligence that is able to recognize and respond to the user's voice commands and questions. Google Assistant is available on a variety of platforms and devices,…

google home

Google Home is a series of smart speakers and home assistants developed by Google. These devices allow users to control various smart devices in their home, listen to music, get information, plan and organize their day, and perform many other tasks…

Gorenje

Gorenje is a large Slovenian manufacturer of white goods. With a 4% market share, it is one of the eight largest home appliance manufacturers in Europe. Appliances are sold under the company's own brands Gorenje, Mora, Atag, Pelgrim, Etna, Körting…
