Do you know what are the worst enemies of an electrical enclosure? Water and dust.
Water and electricity have never get on well, but also the dust can be a real problem, especially when enclosures need to be ventilated from the outside, to prevent the overheating of their components.
How can we protect the electronic equipment from water and dust?
By choosing filters or filters with fans with the correct degree of protection IP (International Protection), depending on the environmental conditions where the switchboard is placed and the possibility that substances that can cause malfunctions could enter. Often this issue is undervalued and ones may give little importance to the validity of the approved product, but when you understand you have chosen the wrong product it can be… too late!
What tests does Fandis run to guarantee water and dust resistance of its products?
The degree of protection of the panels is defined according to standard EN60529 which Fandis refers internally and conducts its own IPX4 and IPX5 water resistance test on fan filters and filters in their in five sizes, while for IP5X tests related to dust protection, Fandis uses external equipped laboratories.
How does a IPX4 and IPX5 test work?
The regulation of the water resistance test IPX4 and IPX5 provide that box that simulate the electrical panels are sprayed with a jet of water that ranges from 10 l/min to 12.5 l/min and a test duration varies from 2.5 minutes to 5 minutes.
At the end of testing, the legislation allows that there may be traces of water inside the box, but in a minimum quantity, and that this will not be propagated in such a way as to damage the components inside the switchgear. Unfortunately, however, the rule does not define a precise amount of residual water and it often happens that some manufacturers declare their products IP54 or IP55 even if quantities of water and dust in real application conditions would create heavy damage to components.
The Fandis engineers not judge an outcome acceptable where there are more than 3 ml of water at the bottom of the panel and where there are sprays on the front of the fan. Because, for us, safety comes first.
