Water Quality Package

Wqp_ss_r

The Thordon Water Quality Package is designed to supply seawater to the propeller shaft bearings for lubrication
and cooling at a minimum flow rate of 0.15 litre/minute/mm (1 US gallon/minute/inch) of shaft diameter and to condition the seawater by removing suspended solids larger than 100 microns (0.004” ) and with a specific gravity of 1.2 or higher; separation to 80 microns (0.003”) is achievable using the 75-150 l/min (20-40 GPM) unit. 

A flow alarm is incorporated to alert the operator to any low water flow condition to the bearings. The Thordon Water Quality Package is designed to operate on a stand-alone basis, or can be fully integrated into the ship's control and monitoring systems to allow operation in an unmanned machinery space.

Thordon offers three Water Quality Packages in configurations designed to deliver flow to suit a wide range of shaft sizes, and provide an appropriate degree of redundancy for the vessel involved. Thordon can, if required, work with integrators, designers and  builders to meet special needs for specific installations.
