Modulating compressors provide better temperature control, lower humidity, and greater energy efficiency compared to fixed capacity compressors. The Copeland Scroll Ultratech compressor modulates between two capacity settings, 67% and 100%. Two internal bypass ports enable the compressor to run at 67% part-load capacity during times when only part-load heating or cooling in needed. When demand increases, the modulation ring is activated, sealing the bypass ports and instantly shifting capacity to 100%.
Running for longer periods at part load capacity (67%) lowers the humidity inside your building and allows the HVAC system to operate more quietly. Capacity adjustments provide better temperature control.
Field testing shows the improved temperature and humidity control provided by Copeland Scroll Ultratech compared to fixed compressors. But, more importantly, your customers will feel comfortable in your building regardless of how hot or cold it is outside.
