Editing Heat exchanger (section)

===Maintenance===
Plate and frame heat exchangers can be disassembled and cleaned periodically. Tubular heat exchangers can be cleaned by such methods as acid cleaning, [[sandblasting]], [[Water jet cutter|high-pressure water jet]], bullet cleaning, or drill rods.

In large-scale cooling water systems for heat exchangers, [[water treatment]] such as purification, addition of [[chemical]]s, and testing, is used to minimize fouling of the heat exchange equipment. Other water treatment is also used in steam systems for power plants, etc. to minimize fouling and corrosion of the heat exchange and other equipment.

A variety of companies have started using water borne oscillations technology to prevent [[biofouling]]. Without the use of chemicals, this type of technology has helped in providing a low-pressure drop in heat exchangers.
