Ingersoll Rand is offering a newly improved single-phase control scheme for its 5 and 7.5 versions of the small UP6 5-15c line of air compressors. It has added a run-on timer and load/unload and blowdown solenoids to improve the reliability and performance of single-phase units in general industrial applications up to 28 cfm. The company says that a compressor that does not include an enhanced control scheme can easily be misapplied and fail in an environment where the compressor starts and stops too many times per hour. Its enhanced control scheme allows the compressor to operate unloaded with the motor continuing to run for the appropriate length of time, ensuring that the reliability and performance of the system is protected.
