Complete Packaged Systems are popular in certain regions, where construction techniques favor a single cabinet system rather than a split system having an outdoor and an indoor unit. Typically, packaged units are installed outdoors at ground level, in a crawl space, or on roof tops for horizontal or down-flow designs. Complete packaged systems are available in the same configuration and utilize the same components as split systems but offer a variety of efficiency options. Unlike a split system, a packaged system contains most components in a single cabinet. The key advantage of a complete packaged system is space efficiency where indoor space is at a premium. According to your needs, you can select from the many types of packaged systems available through Engineered Pressure Vessels.
