Extend System Life Using Thermal Cooling Solutions

Installing a thermal cooling system within an enclosure can lengthen system life and increase control line reliability. Heat build-up in an enclosure is potentially damaging to electrical and electronic devices. Overheating results in decreased life expectancy of costly electrical components and can even lead to catastrophic system failure.

SF Side-Mount Fans from Hoffman

Hoffman (a division of Pentair) offers a variety of cooling solutions, with one of the most popular being the SF side-mount filter fans. Applications for side-mount cooling fans include robotics, automotive assembly, package handling equipment, food and beverage process controls, and wind energy systems. Hoffman’s side-mount filter fans are typically used in relatively clean, Type 1 and Type 3R environments where the temperature inside the enclosure will always be greater than outside the enclosure. The SF series of filter fans come in a variety of sizes and free airflow cooling capacities.
