In our articles we have already considered options for connecting heaters by connection type (star, delta) and by connection sequence (parallel, series). This article is a conclusion in this chain. In the article we have tried to combine the knowledge already acquired to connect electric heating elements. It is an established fact that the use …
A circuit is a drawing of connected wires, cables, clamps, connectors, which are parts of an electrical circuit. A distinction is made between series, parallel and combined connections. Features of a series electrical circuit A simple design looks like this: one lamp is connected to the power supply, a second lamp is connected to it, …

Modern manufacturing is an automatic system in which each process is monitored and adjusted within a specified range. The use of a thermocouple is necessary in processes that require a clear indication of performance. Special sensors called thermocouples are used. They are used over a wide temperature range to transform the energy of the heat …

The manufacturer guarantees the performance of the cartridge heater only if 3 conditions are met. You will need to select a suitable heating element, install it correctly and adhere to the recommended operating conditions. Calculation part The first step is to determine the temperature value of the heating element. It is necessary to calculate the …
Field of use The products are designed for industrial processes and are installed on extruder units, in molds, injection molding machines, glue machines. They are needed in packaging areas, pipelines of liquid and gaseous semi-finished products, heating screw blades, bottle production machines, etc. Consider the most popular destinations. Equipment for polymer injection molding processes. Heaters …
Infrared light lies between the visible spectrum and microwaves. It is one of the methods of heat transfer. Convective transfer determines the equalization of the temperature of objects during the transfer of energy in a liquid, gaseous medium. IF is electromagnetic radiation, in which it is not the atmosphere in the room that heats up, …
By changing the temperature of steel by color is understood the range of shades that can be formed on metal surfaces during the appearance of oxide film. These oxide films are formed from the metal itself when heated. A key condition for the appearance of such a film is considered to be the absence of …
For automation, control of various technological processes at enterprises used various electrical equipment, devices installed in special cells – automation cabinets. The problem is that in most cases they are designed to restrict access and only then to protect the equipment installed in them from negative environmental factors. If the cabinet is installed in a …

Ceramic heating element are used in many areas of human activity. Let’s consider where dry heaters are used first. I. Brewing industry Significant demand for beer combined with a wide offer from different brands forces «to keep the brand» and to produce a high-quality foam product. The process of brewing beer lasts 2-3.5 months. The …
Almost any type of heater, even if it is designed for a current of 220 V, can have several types of connection that differ from each other in the number of phases: one-, two- and three-phase. In this case, there are several connection schemes that will be discussed in this article. Single phase connection This …
