Sullair's expanded line of S-energy series compressors are available in constant speed and variable-speed drive models
S-energy Series compressors are now available in both constant speed and variable-speed drive models, ranging from 15 (11 kW) to 100 (75 kW) horsepower with capacities of 44 to 500 acfm and pressures from 100 to 175 psig. Todays energy costs represent 82% of the expense of compressor ownership. The combination of the S-energy Series energy-saving features has proven most effective in reducing total life cycle costs, more than other compressors of similar design and horsepower range, the company says. Contributing to the energy savings is Sullairs time-tested air-end design with the low restriction inlet valve, low pressure drop air-fluid separation system that prevents energy loss, and a high efficiency fan. Additional energy savings are achieved with optional variable-speed drive (VSD) compressors that provide the flexibility to vary both capacity and pressure to match system demand. On models with variable-capacity control (VCC), Sullairs variable displacement air-end matches system pressure to plant demand. Part load capacity and efficiency can produce additional energy savings up to 17%. All models are available as a complete Performance Air System with optional integral Sullair SRS refrigerated dryers and filters for the most efficient removal of condensate and particulate. Because of their compact design, only a minimum amount of floor space is required. Developed to meet virtually every requirement for cost-effective compressed air, the Sullair S-energy Series compressors are also among the most reliable and maintenance-friendly compressors in the marketplace. Package designs meet the need for a small footprint and enclosures allow routine maintenance of consumable items to be performed from the same side of the compressor. The compressors simplified, concise WS Microprocessor Control System provides critical operating information, including status, temperature, pressure and load/unload set points. A Windows-based PC can be used to remotely monitor, upgrade the software, and set-up system changes.
