Alfa Laval 550557-80 / MK8592140-012 / KK8592040-11-2 DC Purifier Control PCB Circuit Board
When a DC purifier control board fails aboard a vessel or within an industrial separation system, the consequences cascade rapidly — unplanned downtime, contaminated fuel or lube oil, and the risk of catastrophic machinery damage. The Alfa Laval DC Purifier PCB Circuit Board (P/N 550557-80, cross-reference MK8592140-012 / KK8592040-11-2) is the precision electronic heart of the purifier control unit, governing motor start/stop sequences, bowl speed monitoring, and alarm logic. Without a verified OEM-equivalent replacement, restoring safe, compliant operation is simply not possible.
Within the Alfa Laval separator and purifier product family, the 550557-80 board occupies a critical control-layer position. It is engineered to exact OEM tolerances for use in Alfa Laval DC-type centrifugal purifiers widely deployed across marine fuel-oil and lube-oil purification systems, as well as onshore industrial separation processes. As one of the most referenced replacement PCBs in the global Alfa Laval service network, this part is stocked and sourced by operators and MRO procurement teams across Asia, Europe, and the Americas.
