the controllers by the fans and trapped by the electronic components that protrude from the boards inside. Once these
particles stick to the components, they create a textured surface that makes it easier for more particles to get trapped and
accumulate, forming insulating layers over the components.

For this reason,
higher-accuracy models use static cooling rather than fans.
Heat sinks are employed as an integral part of the controller
housing (or mainframe), and since there is no air circulating
internally to carry contaminants, the electronic components
are kept clean and at peak efficiency.
It is critical to establish a maintenance program that

that use fans. The schedule may vary according to the degree
of free-floating dust in the shop, however, if at some point
the dust is not removed, accuracy will be affected, and eventually units may fail altogether.
The static cooling type of controller can be cleaned by
simply wiping off any visible dust from the cabinet's external heat sink. The units are designed to keep potential contaminants away from sensitive areas, so circuit performance
is not affected and the "other half" of your hot runner system
keeps working at peak performance for much longer.
