What is a Heat Exchanger?

Hydraulic Oil Coolers, for example, use cool water or air to remove heat from heated oil. This is an example of a heat exchanger in action. Alternately, you may heat your pool using a Swimming Pool Used Heat Exchanger, which draws hot water from a boiler or a solar collector.

The mediums are separated by the exchanger materials, which carry heat. Unlike an air-cooled heat exchanger, a shell and tube heat exchanger cools a liquid by passing fluids through and over tubes.

Different kinds of heat exchangers

We offer three primary kinds of heat exchangers, each with a wide range of applications.

• Shell and Tube Heat Exchanger

In a shell and tube heat exchanger, a cylindrical shell is filled with a large number of tiny tubes. In the case of used Heat Exchangers, the tubes are positioned into the cylinder using a tube bundle or “tube stack” which can either have fixed tube plates (permanently fixed to the body) or a floating tube stack which allows the tube bundle to expand and contract with varying heat conditions as well as making it easy to remove the tube bundle for servicing or maintenance.

• Plate Heat Exchanger

Plate Heat Exchangers are similar to shell and tube heat exchangers in that they use plates instead of tubes to transfer heat. Depending on the application and fluid, plate heat exchangers are either brazed or gasketed. Refrigeration or food and beverage manufacturing might benefit from their small stainless steel design.

• Air Cooled Heat Exchanger

These heat exchangers are typically employed in transportable applications where there is no constant supply of cold water. In order to save space and improve performance, we offer combination cooling packs (also known as combo-coolers), which integrate a water cooler for the engine jacket, an oil cooler, and a charge air cooler into a single unit. The airflow generated either by a fan or by the vehicle’s motion provides cool air.

Increase the lifespan of a Heat Exchanger by following these steps

A heat exchanger’s operating lifespan may be extended by following a few simple measures.

For the Used Alfa Laval Heat Exchange selection, make sure the design data is correct – If you are giving data to our engineers; make sure it is as exact as possible. Your heat exchanger will not only be thermally efficient, but it will be able to run for a long time as well.

There are a number of factors that might cause problems, such as high flow rates, high pressures, and the presence of uncommon compounds in the fluids (such as acids in cooling water). If our regular materials don’t meet your needs, we’ll typically be able to help you find a suitable substitute.

A heat exchanger’s commissioning and installation depend on using suitable pipe fittings and piping. Please consult the Our Installation and Operation Manual if you have any questions.

Heat exchangers using copper alloy tubes that are intended to cool contaminated, shallow, or brackish seawater are advised to first be operated in clean seawater for several weeks to form a protective layer over the tube material.

Our heat exchangers have been engineered to make routine maintenance and service as simple as possible for our customers. It is possible to clean the internal tube bundle by removing the end caps.

New seal kits are also available from stock and may be purchased via our online shop. Detailed instructions on how to service your heat exchanger may be found in the manual.
