Heat exchangers serve a vital role in mechanical seal applications because they cool the product flush, which extends the life of the mechanical seal and the Mean Time Between Repair (MTBR).

Primarily for use in API Plan 21 and 23 applications, John Crane water-cooled heat exchangers are available in four different sizes to ensure the most efficient solution for each application. Unlike other heat exchangers, John Crane's solution has the product flow on the tube side and the cool water on the shell side. The tube is made of a continuous piece of stainless steel tubing. Threaded process and cooling water connections allow for easy installation and the mounting bracket permits vertical or horizontal installation. Designed for easy cleaning of the shell and coil, water-cooled heat exchangers are ideal for the refinery, petrochemical, chemical processing and pipeline industries.

Air-cooled heat exchangers also are primarily used for API Plan 21 and 23 applications and can be used as an integral part of a packaged seal support system. With three different sizes available, the air-cooled heat exchangers are used on a broad spectrum of applications for a variety of industries including refinery, petrochemical, chemical processing and pipeline. All fans for air-cooled heat exchangers are powdered coated aluminum that is non-sparking. The use of air-cooled heat exchangers eliminates the need for cooling water and provides substantial savings in reduced water usage, waste-water treatment and the elimination of cooling water piping. A standard NEMA or IEC frame motor that is top-mounted, as well as a motor that can be rotated in 90-degree increments ensure ease of installation and maintenance. Further, the John Crane air-cooled heat exchangers offer a five-eighths-inch O.D. by 0.065-inch wall continuous coil for reduced pressure drop and are rated to 2000 PSIG at 500 degrees Fahrenheit.
