It's a fact of life that technology is always advancing. Advances in industrial electronic technology mean more electronic products to put inside of control panels. The past three decades have seen a dizzying array of new technologies, new manufacturing methods, new packaging, and miniaturization of electronic equipment. While dependability and ruggedness have increased right along with capabilities, there remain certain truths about industrial electronics. One of these is that there are still limitations when it comes to high and low temperatures. There are many manufacturers with products for control panel heating and cooling. Electronics manufacturers are very aware of the effects of heating and cooling on their products. They spend a significant amount of effort (and money) to determine what the limitations are and try to make those limitations fit into the generally accepted industrial standards. The most important thing for control panel temperature control is recognizing that there is a need.
