Here on the east coast we are not only roasting from the heat, but simmering like a pot roast in the humidity. And there’s no end in sight. Which, in my sweaty misery, reminds me of the nasty effects of heat on your industrial electronics.
- Use cabinet fans for forced air cooling; these can be installed on existing equipment
- Use heat pipes, a heat transfer mechanism made from a sealed hollow tube of thermoconductive metal such as copper or alumininum which contains a coolant such as water, ethanol, or anti-freeze.
- Even better than heat pipes, invest in a vortex tube exhaust system that can be installed on your equipment cabinets. Compressed air comes in a vortex tube and is converted into two different streams, one hot and one cold. The hot air is muffled and exhausted through a vortex tube exhaust and the cold air is distributed into the control cabinet. Outside air does not need to enter the cabinet protecting it from metallic dirt, dust and moisture. This setup is not too costly and there are several manufacturers of these sytems.
- Do NOT just open equipment cabinet enclosure doors which, while tempting, is an OSHA violation for shock hazard as well as allowing dirt and moisture to get into your equipment
