Emerson’s Copeland Scroll multiples are designed to offer innovative, reliable, and high performing compressors for commercial air conditioning applications. Multiple compressors are connected with a manifold, commonly referred to as tandems or trios. Similar to other modulation approaches, tandems and trios offer improved part-load efficiencies, including Integrated Energy Efficiency Ratio (IEER) and Integrated Part Load Value (IPLV), while maximizing full-load efficiency
