Cases & enclosures


in a war of attrition. The rising temperature vs your electrical equipment… Who will win? Well, the answer to that one is easy:


E


temperature will always win out in the long run. PLCs, drives and transformers are built to work under stressful conditions, but they have their limits. If you take a step back and analyse


your install, you can really cut them some slack and reap the benefits for years to come with just some simple changes in many instances. Why is temperature so bad for equipment?


It actually affects it in multiple ways... Performance

Are you COOL about the internal temperature of your enclosures?

Dependant on the temperature inside your enclosure, this can make a drastic difference to the performance of your equipment. If you check the manual of any PLC, drive or transformer etc. there should be a chart which shows you the rated output compared to the current operating temperature. The trend tends to go like this, as the


temperature rises, the maximum output of the gear in question reduces, and very quickly it drops off a cliff. This means that even if you install brand new equipment into your enclosure, it could actually never be able to achieve it maximum designed output because of the environment you are putting it into. What this means is if you have specific


performance goals you require; you would have to over spec your equipment, which results in higher costs and wasted budget!


very year, there is a battle of two forces. The immovable object comes upon the unstoppable force
