Panel PCs come in many forms. Chief among these are sealed and unsealed panel PCs. An unsealed PPC is often more affordable, but a sealed PPC is just that: a computer with no openings for matter or air to enter or leave.
Greater, Reliable Protection
Such PPCs usually have special fanless designs to address their cooling needs, and are generally built to a higher specification of internal durability and longevity (e.g. the disk drives in a sealed PPC are usually highly resistant to internal wear and tear). All of this helps create a computer that can function in a wide variety of situations, without inviting dangerous particular matter inside or sacrificing dependability.
Sealed Panel PCs Versus Particles
Particular matter varies widely in nature, but exists in many different settings. Large-scale indoor construction or welding can create a large amount of dust or heat. A restaurant setting is full of food particles, while a meat processing area might have a large amount of salt being moved and used within it. In all of these cases, a sealed Panel PC is far more resistant, perhaps even immune, to damage from these particles, which might otherwise enter an unsealed PPC.
On an individual basis many particles are not that harmful to a Panel PC. Dust will not interfere with a PPC’s components on its own. But it will clog the vents an unsealed PPC might use for heating, increasing the risk of damage. Other types of particles such as food particles can cause more immediate damage and malfunctioning, making sealed PPCs particularly important for non-dust particle evasion.
