In plate heat exchangers company Brazetek offers on the USA market a number of innovative models of shell & tube heat exchangers, which differ significantly in design from the well-known, used in Russia shell & tube heat exchangers.

Shell and tube heat exchangers with a coaxial tube c double walls for cooling / heating oils, gases, heat recovery flue gases, corrosive environments. Such heat exchangers are completely exclude a mixture of media, if it is unacceptable for the requirements of technological processes. The application of heat exchangers with coaxial double pipes: the maximum pressure of 300 bar, maximum temperature of 600 0 C.

Shell and tube heat exchangers for use in aircraft technology, with round, fin (made of galvanized steel, stainless steel or special materials on request) and without fins (made of carbon steel, stainless steel or special materials) pipes.

Total production capacity of over 100 species of fin without fin tube heat exchangers. The rich nomenclature of this type of heat exchangers can use them as: - Pre-heaters for boilers in power plants - Coolers and heaters for chemical and petrochemical industries - Economizers to generate steam, hot water, - Heaters for dryers.

Spiral heat exchangers. Of all the compact heat exchangers, this design is the most unique. Typical of their application - this heat transfer between the contaminated streams (the pulp suspension), containing a variety of mechanical admixtures, fibers. They are successfully used in cases where the space for accommodation is limited. The main distinguishing feature of this heat exchanger is in its hydraulics. Constant change in the direction of the flow creates considerable turbulence, higher than Shell and tube, which limits the number and rate of sediments and deposits. At the same time in helical devices, both channels for the liquid, cooked separately from each other, easily accessible for cleaning after removing the lid and remove the helix.

Used spiral heat exchangers and as capacitors. As such, their work is very effective when you install the device directly on top of the column, which provides the use of gravitational forces in the process of condensation. In this case, precluded the need to install drain the drum and pump system pressure and drain lines, the foundation for the base. Reducing the costs of ancillary equipment allows several times to reduce the cost of the capacitor.

Welded heat exchangers. All-welded design of heat exchangers can completely abandon the seals, thereby improving reliability of heat exchangers, expansion of the limits of temperature and pressure environments. Heat exchange of heat exchangers - are welded together profiled plates, which form a package of plates, enclosed in a precisely tailored jacket. Welded heat exchangers are manufactured in single-and multi-way option. In contrast to the heat exchangers of other companies switchgear for multi-pass welded heat exchangers are made not of rubber, and metal, which increases the reliability of the heat exchanger. The direction of flow in a fully welded heat exchangers is performed in countercurrent, forward flow and cross flow. For media containing contamination, the cover shell heat exchanger is made removable, which allows you to remove the package of plates for visual inspection and cleaning. With a fully welded heat exchanger for gaseous media and ammonia in the body shell has a fantastic entry. Design features and reliability of these heat exchangers are important when dealing with extreme temperatures and pressures, where it is impossible the use of conventional heat exchangers. High quality laser welding provides a heat exchanger leak, which completely eliminates the possibility of leaks. The absence of pipe joints welded plate heat exchangers are not affected by internal vibration, and are quite reliable as a mechanical device. High reliability and reduced costs for installation and repair work emphasize the benefits of such heat exchangers. The design of welded plate heat exchangers have a high corrosion resistance. Manufacturing, material and arrangement of connections of each heat exchanger is determined by demand.

Terms of welded heat exchangers: working temperature from -200 to 950 0 C; ultrahigh pressure up to 100,0 bar.

We are confident that by applying heat exchangers Company Brazetek You made the right choice, using technically advanced and truly cost-effective heat transfer equipment.
