The Contamination Problem
Hydraulic fluid and lubricating fluids become polluted with use; a build-up of varnish, siloxane, salts, particulates, and water causes equipment wear, reduces efficiency, and risks breakdown. Typically, this is resolved by regular fluid changes and routine maintenance. This is expensive, often awkward, and polluting.
Heavy fuel oils contain similar pollutants which can contaminate and wear the fuel system. These are burnt off in the combustion cycle, resulting in smoke and particulate emissions, particularly at start-ups.
The Delta-Xero® patented nanofiltration technology removes water, siloxane, varnish, particulates, and salts from hydraulic oil, lubricating oil, and fuel oil down to 0.1 Micron particle size. Well below ISO 4406 (ASTMD975) limits.
Installed in a correctly designed offline filtration system, Delta-Xero filter cartridges reduce operating fluid and fuel oil pollutants to very low levels. Significantly extending operating fluid life, reducing maintenance requirements, extending equipment life, and helping fuel oils burn more cleanly.
Delta-Xero® fluid conditioning systems extend fluid life, reduce maintenance requirements, extend equipment/component life significantly, and improve overall system efficiency and reliability by up to 80%. Taken together these save time, and consumables and achieve significant reductions in cost.
Fluid Condition Monitoring
Delta-Xero® fluid conditioning results in longer operating fluid and equipment life. The cartridges are easy and quick to change and can include remote fluid condition monitoring to ensure optimum fluid and filter replacement cycles.
Lower Environmental Impact
Fewer operating fluid changes reduce the need to dispose of used hydraulic fluid and lubrication oil. Reduced equipment maintenance reduces system downtime and reduces the need to work on equipment in difficult or polluted environments such as wind turbines, power generation, and waste processing.
The Delta-Xero® filter cartridge is manufactured from recycled material and is recyclable, the filtration media is recycled, and the used filtration media can be disposed of in waste-to-energy systems.
Single, and multiple filter cartridge systems suit a wide range of flow rates from <1 to 20L per minute, with capacities of 100 to 120,000 L.
Delta-Xero® has extensive, practical fluid conditioning experience and a sample-based test and measure approach to the implementation of its fluid conditioning systems and offers a full backup and after-sales service via its global distribution network.
Delta-Xero filtration systems have applications reducing water and varnish contamination in hydraulic systems for cranes, steering gear, hydraulic control systems, and gearboxes in the Marine industry, on and offshore. Extending the life of the hydraulic and lubricating fluids and extending maintenance cycles with consequent increases in uptime and savings of fluids; leading to notable operating cost reductions and environmental improvement.
Delta-Xero filtration technology has been applied to the filtration of fuel oil in a dockside environment. Reducing the water and particulate contamination of the fuel by up to 95%. The filtered fuel burns more cleanly, producing a measured reduction in CO2 of 7%-33% from full load to idle, reductions in nitrous oxide emissions of over 50% at full load, reductions in SO2 levels of 10% to 45% depending on load
The Delta-Xero filter reduced particulates in the fuel by over 99.5% well beyond ISO4406 limits, resulting in a visible reduction to smoke emissions from the engine.
