Deckhouse for Alfa Laval PureBallast 3 Ex - 1

Alfa Laval has developed standard deckhouses to fit Alfa Laval PureBallast 3 Ex ballast water treatment systems. Each deckhouse is delivered as a pre-assembled solution, including the PureBallast 3 Ex system and all piping inside the deckhouse, for easy integration into the vessel. For PureBallast 3 Ex system details, please refer to the Alfa Laval PureBallast 3 product leaflet. Application A large portion of the world’s tanker fleet uses submersible pumps, e.g. Framo pumps or the equivalent, to eliminate the need for a pump room and maximize space for the transport of product. This poses challenges when installing a ballast water treatment system, as it means there is no internal space available. A deckhouse for PureBallast 3 Ex offers a solution when the pump room is lacking or offers too little space for the installation. Benefits • Pre-assembled PureBallast 3 Ex system in standardized deckhouse • Durable construction with marine-approved steel (Grade A with 3.2 certificates) • Climate regulation through integrated HVAC • DNV-GL type approval covering both deckhouse and treatment system • Possibility to transport the deckhouse in a pallet-wide high cube container (40’/20’/10’) • Full backing from Alfa Laval’s global service organization Configuration The flow-related components of the PureBallast 3 Ex system (UV reactor, filter and CIP unit) are contained within the deckhouse, while the lamp drive cabinet and control cabinet are installed outside the deckhouse and within the vessel’s safe zone. Safety classification All components and wiring inside the deckhouse are classified for use in hazardous areas in accordance with the IEC 60079 series of standards: • Zone 1 • Explosion group IIC • Temperature class T4 (135°) Type approval The standard deckhouse configuration, including the PureBallast 3 Ex system, is type approved by DNV
