FAQ
Why Is Temperature Control Important for Machine Running?
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.
