resin

Resin is a sticky and viscous liquid found in plants, trees and some types of animals. It contains a mixture of organic compounds that can be in liquid or solid form and can have different compositions depending on the type of source. Resin is…

resistive load

A resistive load is a type of electrical device or load that creates electrical resistance and converts electrical energy into heat. This means that the resistive load converts the electric current into thermal energy, heating it up. This load is…

Response time

Response time (or reaction time) in heating refers to the time that elapses between a change in room temperature and the reaction of the heating system to this change. This time can be critical for reaching a comfortable temperature in the room and…

return valve

A non-return valve in heating is a mechanical device that allows the flow of liquid or gas in one direction only and prevents its return or reverse flow. It is a type of valve that opens or closes the flow path depending on the flow…

Room temperature

  Room temperature is a physical quantity that describes the distribution of heat in space. It expresses how the temperature changes at different points in space. The basic idea is that the temperature is not the same at every point, but can…

RS communication

RS communication is a standardized serial communication protocol that is used to transfer data between different devices. This protocol was developed by the Electronic Industries Association (EIA) in the USA and is also known as EIA-232 or…

RS-232

RS-232 (Recommended Standard 232) is a serial communication protocol and physical interface used to transfer serial data between various devices such as computers, peripherals, modems, printers, and other electronic devices. RS-232 was developed in…

Rubber

Rubber is a natural or synthetic polymer characterized by elastic properties. It is known for its ability to deform under pressure and return to its original form when the pressure is released. Rubbers can be flexible to rubbery depending on their…

SALUS

about company SALUS is a renowned global supplier of intelligent solutions for heat management and heating regulation. Its scope extends to more than 80 countries and the company specializes in the development and production of quality products…

Sand filtration

Sand filtration serves to capture impurities contained in the water. They use natural principles for this. The pool water passes through a sand filter cartridge in which mechanical impurities are captured and clean water is returned to the pool. The…

sanitary distribution systems

A system developed for plumbing and heating/cooling systems. It consists of PEX-b pipes and brass fittings, which are sealed into the pipe using copper rings that compress the pipes on the fittings. The pipe used is manufactured in accordance with…

Saswell

Saswell is a company focused on the development and production of intelligent control systems for homes and commercial buildings. Based in China, it is one of the leaders in the field of intelligent devices for controlling heating, cooling…

scale

Scale is a precipitated coating of calcium carbonate on the walls of vessels or pipes through which hard water, whose temperature is lower than 100 °C, is conducted or mainly heated and then cooled. The basic component of scale is usually calcium…

SCOP

The abbreviation SCOP stands for "Seasonal Coefficient of Performance," which translates to "Seasonal Coefficient of Performance." SCOP is a measure used to evaluate the energy efficiency of heat pumps and air conditioning systems throughout the…

screw

A screw (colloquially a screw or a screw, unwritten a screw or a screw) is a machine part that is part of dismountable joints, based on the principle of interlocking external (bolt) and internal thread (nut). By turning the thread, the screw moves,…

screw conveyor

A screw conveyor is a mechanical device that is used to move materials, most often powdery or granular, from one place to another. It is a type of conveyor that uses a rotating screw or screw to transport material through a pipe or…

Sealant

Sealant is a material that is used to join or fill gaps, cracks and fissures in various materials. Its main function is to create a tight and solid bond between two surfaces or to fill gaps to prevent the penetration of water, air, dust or other…

Selective absorption

Selective absorption is a technology used on solar collectors to increase their efficiency in absorbing sunlight. It is a special surface or coating on the absorption surface of the collector that is designed to selectively absorb solar radiation…

Self-gravity circulation systems

Self-gravity circulation systems, also called gravity circulation systems, are simple and energy-saving ways to ensure the circulation of hot water in hot water distribution systems without the need for a pump. The principle is to use the natural…

sencor

SENCOR is a Czech brand that specializes in the production of household appliances and electronics. It was founded in 1969 and gradually became one of the most famous appliance brands in Central and Eastern Europe. SENCOR is characterized by…

sensor

A sensor or a sensor or a receptor is a physical system, technical device or, in a broader sense, also a biological organ, reacting to changes in the measured quantity (physical, chemical) immediately, or reacting to the time course of the…

serial port

A serial port is a communication interface on electronic devices that allows data to be transferred between these devices and other peripheral devices or a computer in a serial manner. A serial port is also known as a serial interface or COM port…

servo drive

A servo drive is a device that is used to control or move a certain mechanical system using an electric motor or a hydraulic actuator. Its main purpose is to provide precise and accurate movement control, often with the ability to adjust speed and…

setrilizer
