AK-PC 782A - pack controller for CO2

The new AK-PC 782A offers fully integrated pack control in transcritical CO₂ booster packs. Where previously multiple controllers were needed, AK-PC 782A performs all necessary control functions as one, integrated solution. The integrated control leads to precise regulation and high efficiency even in challenging operational conditions. AK-PC 782A handles up to eight MT and four LT compressors.
