Lowering the acid content of the fluid is a critical step in fluid remediation and preventative maintenance. Treatment with the IX Control fluid treatment system brings the fluid back to its OEM specified acid level for proper operation and extended fluid life. The unit does not release by-products typically found in traditional acid removal systems, such as water from wet resins or sludge from Fullers earth and activated alumina systems.

Efficiency and Ease of Use
Acid levels in the fluid can be lowered below OEM specified limits by recirculating it through the IX Control fluid treatment system. The stand alone system is equipped with a specially formulated resin, in a semi dry package. The skid uses resin cartridge in the vessel. They can easily be changed and send for replenishment. Each set of resin cartridge will typically treat 2000 litres of acidic phosphate ester and bring the TAN level down to below 0.1 from 0.5 mg of KOH/ ml of oil based on the test results carried out by us.

Operation
The IX Control fluid treatment system is connected to the main oil reservoir and circulates the oil at a rate of up to 20 litres per minute through the pump and strainer to acid reduction unit and a high efficiency cartridge filter. With each pass through the system, acid compounds are captured on the resin and the fluid is returned to the reservoir.

The resin cartridge can be replaced with new one or used cartridge is to be sent back for replenishment once the acid levels start increasing during usage.

Operation Methodology of Acid treatment skid:
The acid fluid treatment skid is a portable or stationary system designed to reduce TAN (Total Acid Number) in phosphate ester based hydraulic systems.

The skid is manually controlled and equipped with a pump and motor to circulate the fluid into and out of the fluid treatment vessel. The fluid treatment vessel contains media in disposable element format. It is also equipped with particulate removal filter to prevent particulate contamination entering into the system. The skid is designed to operate on continuous off-line recirculation configuration.

The rate and efficiency of TAN reduction by Acid treatment unit depends on a number of factors which include, but are not limited to, the type of fluid, the type of acid, turbine type, system operating conditions, duty cycle, temperature, nature and extent of the acid, acid generation rate and other contaminants present in the fluid system. One resin cartridge of this unit is capable o binging down tha TAN value by 0.50 for oil quntity of 800 to 1000 litres of EHC fluid.
