HAKL

O spoločnosti  about company The company headquarters is located in Ivanka near the Danube (approx. 8 km from Bratislava). Construction of the production complex began in 1996. Today, assembly halls with an area of more than 1,000 m² are in…

Hard water

Hard water is water that contains a high content of minerals, especially calcium and magnesium. These minerals contribute to the formation of scale and can have a negative effect on household appliances, pipes, taps and other water…

Heat exchanger

A heat exchanger or heat exchanger is a device used to exchange energy between systems and objects with different parameters. Exchange stations are part of factories or housing estates. They ensure heat distribution for heating individual objects…

Heat exchangers

Heat exchangers are an important part of many systems and processes that require the transfer of heat from one medium to another. These devices are used for efficient heat transfer between hot and cold media. Here are some important facts about…

heat loss

Heat loss is a process in which heat escapes from an object or system to the surroundings. Heat losses can occur in different situations and are caused by different factors. The main source of heat loss is the thermal conductivity of materials.…

Heat Pump

A heat pump is a thermodynamic device that serves to transfer heat from one place (heat source) to another (target heat removal) using the heat pump cycle. Its main purpose is to transfer heat from a lower temperature to a higher temperature using…

Heat resistance

Heat resistance is the ability of a material to withstand high temperatures and to protect against direct exposure to fire, hot gases and radiation. Materials that have high heat resistance are designed to maintain their structural, insulating or…

heating burner

A heating burner is a device used to burn fuel and generate heat. It is a part of the heating system that ensures the supply of fuel and its combustion in order to produce heat for heating the building. The burner can be gas, oil, solid fuel or…

heating circuit

An electric heating circuit is a wire that is made to a certain length and cannot be shortened. The installation company must install the entire length of the heating cable. Each conductor is terminated by a supply conductor, the so-called cold end,…

heating coil

A heating coil is a component of a heating system that is used to transfer heat from a heating medium (often hot water) to the surrounding environment, such as a space in a house or building. This coil is usually made of metal, such as…

heating curve

The heating curve is a graphical representation of the relationship between the outside temperature and the temperature setting of the heating system. This concept is often used in central heating systems, where the room temperature is regulated…

heating elements

Heaters are devices intended for heating and dispersing heat in the interior in order to ensure a comfortable temperature and room heating. These bodies are part of heating systems and can be used in homes, offices, commercial premises and other…

heating mat

A heating mat is an electric heating pad or tape that is installed under a floor covering (eg ceramic tile, floating floor, linoleum, etc.) in order to provide effective and comfortable thermal insulation in a room. These heating mats usually…

heating medium

A heating medium is a substance that is used to transfer heat from a heater (such as a boiler, heat pump, or solar system) to heating elements (such as radiators or underfloor heating) in heating systems. Its task is to transfer heat from the…

Heating output

Heating output (often also called thermal output) is a physical quantity that indicates the amount of heat that can be produced or transferred by a heating device, such as a heater, heat pump, boiler or electric heater. This quantity is measured in…

heating system

Each central heating system consists of a heat source, a characteristic pipe system for heat distribution and a heating element. Special heating systems consist of a heat source and a heating element, which are built into one device and are located…

heavy metals

Heavy metals are metallic elements with increased density and weight that occur naturally in the earth. Some of them are essential for the normal functioning of organisms in very small amounts, such as iron, zinc, copper, manganese and others.…

HEPA filter

A HEPA filter is a type of air filter. Its name is an acronym from the English high efficiency particulate arrestance, i.e. a highly efficient filter of air particles. This type of air filter is able to remove particles with a size of 300 nanometers…

HEPWORTH

The HEPWORTH heating system is a flexible, comprehensive and, above all, demountable installation system for floor heating, radiator heating and water distribution. Among the biggest advantages of the system are its quick assembly without tools,…

HEWALEX

  HEWALEX has more than 30 years of experience. What sets us apart is innovative production technology and care for the highest quality and efficiency of the products in our offer. We are constantly improving our products to meet the high…

hmax

The abbreviation "hmax" is most often used to denote the maximum lift/discharge head (or maximum pumping head) of the pump. In the context of pumps, this value indicates the maximum height to which the pump can pump liquid from a reservoir or other…

HNBR

The abbreviation HNBR stands for "Hydrogenated Nitrile Butadiene Rubber" in English, which in Slovak is "Hydrogenated nitrile-butadiene rubber". HNBR is a special type of synthetic rubber with increased resistance to heat, oil, ozone and…

Honeywell

  Honeywell has a rich history that began in 1885. Founded by Mark C. Honeywell, it originally focused on manufacturing thermostatic equipment. It gradually grew and expanded its portfolio of products and services. During the 20th century,…
