LYC-25J – Compact Oil Purifier with Coalescence Dehydration and Multi-Stage Filtration

Product Performance

Efficient Coalescence Dehydration

The unit rapidly removes free water and emulsified water from oil,

 improving key physical and chemical properties including viscosity, water content,

 and oxidation stability. By eliminating free water, it helps prevent component corrosion,

 filter blockage, and oil additive depletion, extending both oil and equipment service life.

Multi-Stage Precision Filtration

Equipped with a multi-stage filtration structure, the unit effectively intercepts solid contaminants 

such as dust, metal debris, and oxidation by-products. This ensures oil cleanliness meets 

operational requirements and provides reliable protection for hydraulic and lubrication systems.

Compact and Mobile Design

The small footprint and flexible movement allow easy operation across various workshop 

scenarios. The unit can be quickly deployed wherever needed, making it ideal for facilities

 with multiple hydraulic systems or frequent oil maintenance tasks.

User-Friendly Operation

Low operating noise, low energy consumption, and straightforward controls support stable 

long-term continuous operation. Personnel can operate the unit with minimal training, 

reducing the need for specialized supervision.

· Machinery manufacturing

· Metallurgy (steel mills, rolling mills)

· Mining and mineral processing

· Electric power generation (turbine oil maintenance)

Economic and Operational Benefits

· Reduces oil replacement frequency – extending oil service life through continuous 

contamination control

· Prevents equipment wear – removing abrasive particles and free water that cause 

component damage

· Decreases maintenance downtime – enabling quick online purification without system

 shutdown

· Saves operating costs – low energy consumption and long filter element service life

Frequently Asked Questions

Q1: What types of oil can this unit handle?

A1: The LYC-25J is suitable for low-viscosity hydraulic oil, lubricating oil, and gear oil.

 For other fluid types, please consult our technical team for compatibility verification.

Q2: Can this unit remove dissolved water from oil?

A2: The unit is primarily designed for free water and emulsified water removal. 

For dissolved water removal, additional vacuum dehydration equipment may be required 

depending on the specific application.

Q3: How often should the filter elements be replaced?

A3: Replacement frequency depends on the contamination level of the oil being processed. 

The unit is equipped with a differential pressure indicator that signals when the element is 

saturated and requires replacement.

Q4: Is the unit suitable for continuous operation?

A4: Yes. The motor and pump are designed for industrial-grade continuous duty. 

The unit supports long-term stable operation with routine maintenance.

Q5: Can I move the unit between different machines?

A5: Yes. The compact and mobile design allows the unit to be moved easily between different 

equipment within the workshop. Quick-connect hose fittings enable fast setup and connection

 to various oil systems.

Q6: What is the difference between this unit and a standard filter cart?

A6: Unlike standard filter carts that primarily remove solid particles, the LYC-25J also breaks 

oil-water emulsions and removes free water. This makes it particularly suitable for oil that has 

been contaminated by water ingress.

Q7: What documentation is provided with each shipment?

A7: Each unit ships with a factory test report, operating manual, electrical schematics, 

and dimensional drawings. Material certificates for pressure components are available upon

 request.

Q8: Is customization available?

A8: Yes. Custom configurations including special power supply voltage, hose lengths, 

and connector types can be arranged based on site-specific requirements.

Summary

The LYC-25J coalescence dehydration oil purifier combines solid particle filtration and free 

water removal in a single compact unit. With multi-stage filtration, efficient coalescence 

dehydration, and mobile design, it provides a practical solution for maintaining oil cleanliness 

and extending oil service life in hydraulic and lubrication systems across various industries.
