Industrial computers are designed to work in a harsh and heavy environment, in harsh industrial conditions. They are exposed to extreme temperatures, vibrations, often without adequate ventilation, in dust and dirt where office computers would not have a chance to work longer
Industrial computer cases are usually made of aluminum or some other high-performance metal alloy in order to properly dissipate the high temperature of the processor.
Even short-term overheating of strategic components such as the processor, memory or disk can permanently damage your computer. And that is why this element is so important in the entire design of an industrial computer.
Most of the computer equipment dedicated to the industry is a fanless, effective solution and in the case of ventilation, filters are used to protect against particles.
Computers dedicated to the wet environment have IP65 and higher certificates, ensuring effective operation in a harsh environment.
