Delta-Xero manufactures offline fluid conditioning systems for hydraulic, lubrication, fuel and other operating fluids

Why Delta?

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-up.

Nano Filtration

The Delta-Xero patented nano filtration 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.

Delta-Xero Filters

Reduced Maintenance

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.

Commercial Benefits

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, 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 used filtration media can be disposed of in waste to energy systems.

Filtration 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.
