Control solutions to the Oil & Gas, Chemical and Petrochemical industries world wideControl-Care’s Antisurge ControlApplication (ACA), designed forpackaged compressor units, protects the compressor from surge efficiently and reliably. An elegant and affordable solution for packaged compressor units using Honeywell’s Control Edge product family.Control-Care’s method of accurately defining the surge line over a wide range of changing process conditions allows setting of the control line for optimum surge protection without unnecessary recycling or blow-off, compatible with industry standard API672 (AIR).
