Before Filtration After Filtration Initial Reading Final Reading

Liasotech conducted a successful oil cleaning demonstration at one of our customer's sites in the Plastic industry. This demonstration was crucial for the customer, who had previously faced multiple failures with other filtration companies in their attempts to clean hydraulic oil to the required standards.
Problem
Upon initial assessment, the hydraulic oil was tested and found to have a cleanliness level of NAS >12. This was significantly higher than the system's requirement of NAS 5. The excessive contamination in the hydraulic oil posed a serious risk to the machinery's performance and longevity, necessitating immediate and effective intervention.
Solution
In response to the customer's challenge, Liasotech deployed a skilled service engineer to the site for an initial assessment. Upon testing, it was confirmed that the hydraulic oil's cleanliness level was indeed at NAS 12. To address this, we installed a 12 LPM oil filtration machine equipped with 3-micron filters, all under the supervision of our service engineer. The filtration process commenced and continued non-stop for approximately 48 hours.
Result
The outcome of our intervention was highly successful. The filtration system reduced the oil's cleanliness level from NAS 12 to the desired NAS 5, meeting the stringent requirements of the customer's molding equipment. This significant improvement demonstrated the effectiveness of Liasotech’s technology and expertise in oil filtration.
Benefits
The successful filtration of the hydraulic oil brought multiple benefits to the customer. Firstly, achieving NAS 5 ensured the optimal performance and longevity of their equipment, reducing the risk of breakdowns and maintenance costs. Secondly, the customer, impressed by the results, expressed their interest in placing more orders. This not only solved their immediate problem but also paved the way for a long-term partnership with Liasotech, ensuring sustained equipment efficiency and reliability.

The Problem
An integrated steel plant in Odisha faced a significant challenge in maintaining oil cleanliness within one of its hydraulic systems, which has a 3000 liter tank capacity. Despite operating an ELC filtration machine continuously 24/7, the plant consistently recorded high particle count readings at NAS 10 or higher. Such high contamination levels posed a risk to the efficiency and longevity of the hydraulic system, making it critical to find a more effective solution to ensure system reliability and performance.
The Solution
To address the contamination issue, the plant official decided to replace the ELC filtration machine with our Hydraulic Oil Filtration System (HOFS-16). The HOFS-16 system was equipped with our finest 3-micron absolute filter elements, specifically chosen to eliminate particulate contamination in the hydraulic system effectively.
The Results

Initial Particle Count Reading - 09:30AM
The initial measurement taken at 9:30 am showed a particle count of 20/19/11, equivalent to NAS Class 10. This level of contamination was considerably high and unsuitable for the hydraulic system's optimal performance.

Final Particle Count Reading - 05:30PM
After operating the HOFS-16 filtration system throughout the day, a subsequent particle count reading was taken at 5:30 pm. The reading showed a significantly reduced particle count of 15/14/09, equivalent to NAS Class 5. This indicated a much cleaner state of the hydraulic oil, well within acceptable levels for such systems.
The Benefits:
Implementing the HOFS-16 filtration system brought several advantages:
The significant reduction in particulate contamination improved the hydraulic system's reliability and operational efficiency.
Cleaner oil helps reduce wear and tear on system components, extending their lifespan.
With lower contamination levels, the frequency of maintenance and associated downtime decreases, leading to cost savings.
Maintaining cleaner oil enhances the overall performance of the hydraulic system, contributing to smoother operations and improved productivity for the steel plant.
