Vokes self contained custom built 4m³/hr Lubricating Oil Filter Coalescer module complete with pumps, heater and control system supplied to Alstom for the Connahs Quay Power Station steam turbine lubricating oil system.
Vokes 361/1 Lubricating Oil Filter Coalescer complete with pump. Several of these units, specifically designed to resist shock, have been supplied for purifying gearbox lubricating oil in submarine applications.
The Vokes Filter Coalescer is designed for the removal of solids and water from mineral lubricating oils used in lubricating or hydraulic systems.
This makes it an ideal solution to those applications where water can contaminate oils through condensation, seals or glands.
The Vokes Filter Coalescer can be supplied by itself for the customer to pipe in to his system or in a variety of modules which can include pumps, heaters and control systems to provide self contained purification systems.
The Vokes Filter Coalescer is used in industries such as Power Generation, Sugar Refining and Marine, to provide the purification of lubricating oils in main and auxiliary steam turbines, gear boxes, stern tube and low pressure hydraulics systems. It is either used as a bypass system on the main tanks or from a bleed off the main oil supply line.
For solids removal, an efficiency of 98% at 5 microns is achieved.
The Vokes Coalescer will reduce free water levels in lubricating oil by 99% or more fo initial concentrations of around 8%. Free water can be reduced to better than 100ppm depending, of course, on the specific type of oil and the conditions encountered. So, for typical steam turbine applications at, for example, an oil flowrate of 7m/hr this could mean that over half a cubic metre of water per hour would be removed.
The standard range of Filter Coalescers is designed to handle flow rates upto 60l/min (3.5m³/hr), with many units being custom designed to meet the customers specific system and industry requirements.
