Why Is Temperature Control Important for Machine Running?

Boost Efficiency and Improve Productivity

The service life of electronic components is directly related to the ambient temperature. Generally, electronic components will have a shorter service life for every 10 degrees higher than the normal indoor temperature.

For High temperature environment:

As a result, the operation efficiency of the equipment will decrease and abnormal operation will occur, and the characteristics of the rubber material will also change.

For low temperature environment:

Below the dew point temperature will cause condensation on the surface of the equipment, increasing the risk of equipment corrosion and abnormal operation of the equipment.

Enhance the service life of electronic components and contribute to the efficiency of the enterprise！
