DX Systems: 50 Years of the Engineers Newsletter

It is June and we are half-way through our Engineers Newsletter 50th anniversary celebration! As the temperature and humidity begin to rise, our appreciation for air-cooling equipment increases. One of the most prevalent cooling systems applied in our homes and small buildings are direct expansion (DX) split systems. Over the years, seven percent of the Engineering Newsletters have covered topics involving split systems. According to one EN, a split-system is nothing more than a packaged unit split in half, one half staying on the roof and the other half moved indoors into a central station air handler. While this is not always the case, it is a good place to start.
