Evaporation

Heat exchanger evaporator

When it comes to such a heat exchanger, the position of freon evaporator of the refrigeration unit immediately comes to mind. In this case, they are used to cool products and various process flows due to the boiling of working agents. However, this is hardly the only area of their application. In industry, it is common to find various positions where one of the working fluids boils completely, or partially, eventually forming a vapour-liquid mixture. Evaporators of liquefied gas, ammonia, freon, oil products, water, alcohols, this is not a complete list of positions where a heat exchanger is needed. Various types of heat exchangers may be used: shell-and-tube, welded, brazed, and even gasketed, although this is not recommended due to the presence of rubber seals and high risk of depressurization.
Shell and tube evaporator
They are installed in most process positions. This is due to the fact that they were invented much earlier and therefore took the main place in the industry. Other types of heat exchange equipment have to fight for their “place in the sun” constantly competing with them. But there are process positions where shell-and-tube evaporators are difficult to replace with another type of equipment, despite their advantages. One of these positions may be called a reboiler. Cube product from column partially boils in it. Due to the non-standard design of this equipment, alternative solutions are rarely considered for its place.
Buy freon evaporator (of the refrigeration unit)
Freon evaporator is the main element of an industrial refrigeration unit. In this device, the working agent boils and the product is cooled. The process of phase transition of fluid from a liquid into a gas state requires a significant amount of heat energy, which is taken from the cooled liquid. Glycol solution is most often cooled there. Its main difference from more common water is that it can not freeze at low temperatures, which makes it possible to use the refrigeration unit more efficiently and obtain lower temperatures of the cooling fluid for further use in technology. Buying an evaporator is quite simple. To do this, you will need to fill out a questionnaire, indicating the main operating parameters and send it to us. Or just call us and tell the manager the required parameters. After that, we will choose the necessary equipment and provide a technical and commercial proposal. Our company offers various types of equipment for such positions: brazed device, welded and welded heat exchanger with a removable shell, if necessary. You just need to make your choice.
Also, at the request of the customer, dual-circuit options may be offered. In this case, two (or more) circuits of the refrigeration unit freon are supplied to the heat exchanger separately, independently of each other. In this case, the cooled fluid is supplied into it in a single flow. This arrangement is used when several refrigeration units are used to cool the product and it makes no sense to install such products on each of them.
