Centurion™ rooftop units are available in 12.5-, 15-, 18-, 20-, and 25-nominal ton capacities. They have independent, dual, or triple refrigerant circuits with thermal expansion valves. Each unit comes with ComfortLink™, an onboard microelectric controls system that provides advanced user diagnostics, two-way remote monitoring, and demand control ventilation capability. The scrolling marquee acts as a window into the unit’s operation and has diagnostic read/write functions. E-Coating is an impermeable epoxy coating that is adhered to the unit’s specially prepared fin coil surface, the company says; it is intended for corrosive urban, industrial, or coastal/marine locations.
