    Industrial Heat Exchangers

    Industrial heat exchangers are technical devices that exchange heat between two media at different temperatures. Shell-and-tube equipment refers to devices in which the heat transfer surface between the two flows is formed by tubes enclosed in a shell, and heat transfer occurs through the surface of these tubes. Shell-and-tube coolers are water heat exchangers for cooling various petroleum products. They have a similar design to shell-and-tube coolers. The only difference is that recirculated water is used as the cooling fluid. Heat exchangers – equipment for various purposes, with designs ranging from shell-and-tube to plate-and-fin, are used in refrigeration engineering. Devices with phase transition of heat-exchanging media: condenser and evaporator. Heat exchange devices include condensers, evaporators, and cooling units. The following types of condensers are distinguished: horizontal shell-and-tube, vertical shell-and-tube, evaporative, and air-cooled.

    FAQ

    How to choose between a shell-and-tube or plate heat exchanger?

    The choice depends on the pressure and type of medium. Shell-and-tube units are better suited for ultra-high pressures and highly contaminated media, as they are easier to clean internally. Plate heat exchangers are ideal for compact installations and processes where maximum heat transfer efficiency at low temperature differences is essential. ASMEX PETROCHEM engineers will help you choose the optimal type for your application.

    What innovations are used to improve heat transfer efficiency?

    We use internally corrugated tubes and special flow turbulators. This disrupts the liquid boundary layer at the walls, increasing heat transfer by 30-50% without increasing the unit's size. In the context of modernizing plants in Uzbekistan, this allows for increasing the capacity of existing lines without expanding production space.

    How to extend the service life of a heat exchanger when working with hard water?

    The main problem is scale. We design for chemical or mechanical cleaning without complete dismantling of the unit. The use of special steel grades and protective coatings prevents pitting corrosion, and proper calculation of flow rates minimizes salt deposition on the walls.
