FAQ (Frequently Asked Questions)

Q1: What is the primary function of the HCP Series oil purifier?

A: The HCP Series utilizes advanced "coalescing and separating" dehydration 

technology to remove solid particles, emulsified water, and free water from turbine oil

 and various industrial oils. It integrates precision filtration and high-efficiency dehydration

 into a single compact unit.

Q2: What oil cleanliness level can the HCP Series achieve?

A: After treatment, oil cleanliness can reach NAS Class 5 (NAS 1638), meeting the stringent 

requirements of high-precision equipment such as turbines, servo systems, and critical hydraulic machinery.

Q3: What are the three filtration stages of the system?

A: The filtration system is divided into three stages:

· Suction filtration – protects the pump from large particles at the inlet

· Pre-filtration – removes intermediate-sized contaminants

· Fine filtration – achieves high-precision removal of fine particles

This staged approach ensures consistent and reliable performance while extending filter element service life.

Q4: What types of water can the HCP Series remove from oil?

A: The system effectively removes both emulsified water (water chemically bound in the oil) 

and free water (water present as separate droplets), ensuring the oil is thoroughly dehydrated 

and protecting equipment from water-related damage.

Q5: What fluids are compatible with the HCP Series?

A: The HCP Series is compatible with turbine oil, hydraulic oil, lubricating oil, and other industrial oils,

 making it a versatile solution across power generation, metallurgy, petrochemical, and machinery 

manufacturing industries.

Q6: How does the automatic drainage function work?

A: The system is equipped with an auto-drain function that automatically removes separated 

water from the collection chamber. This enables truly unattended operation, reducing the need

 for manual monitoring and intervention.

Q7: What are the key performance advantages of the HCP Series?

A: The HCP Series delivers:

· Integrated functionality – combines filtration and dehydration in one unit

· High-capacity continuous processing – handles large flow rates with high efficiency

· Superior filtration precision – achieves NAS Class 5 cleanliness

· Long filter element service life – high dirt-holding capacity reduces replacement frequency

· Energy-efficient operation – low energy consumption keeps costs under control

· Oil quality protection – preserves oil's physical and chemical properties, extending oil life

· Simple operation & maintenance – user-friendly design with minimal training required

· Automatic drainage – enables unattended operation

Q8: What industries is the HCP Series best suited for?

A: The HCP Series is widely used for precision filtration and dehydration of industrial oils across:

· Power generation – turbine oil purification for steam and gas turbines

· Metallurgy – hydraulic and lubrication systems in rolling mills and continuous casting

· Petrochemical – process oils and lubricants in refining and chemical plants

· Machinery manufacturing – hydraulic fluids and lubricants in heavy equipment and precision machinery

Q9: What is the "coalescing and separating" dehydration technology?

A: The technology works in two stages:

1. Coalescing stage – oil passes through a specialized coalescing element that forces tiny emulsified 

water droplets to combine into larger droplets.

2. Separating stage – the enlarged water droplets are then repelled by a hydrophobic separating element,

 allowing them to settle and be drained away while the dry oil passes through.

This achieves efficient removal of both free and emulsified water without heating or chemical additives.

Q10: How often do the filter elements need to be replaced?

A: Both the pre-filter and fine filter elements feature high contaminant capacity and extended service life, 

reducing replacement frequency compared to conventional filters. Actual replacement intervals 

depend on operating conditions, oil contamination levels, and flow rates. The differential pressure

 indicator will signal when replacement is required.

Q11: Does the HCP Series alter the quality of the oil?

A: No. The system is specifically designed to preserve the physical and chemical properties of 

the oil while removing contaminants. It effectively extends oil service life without degrading its

 performance characteristics.

Q12: Is the HCP Series easy to operate?

A: Yes. The system features a user-friendly design that requires minimal training for operation 

and routine maintenance. The combination of simple controls, automatic drainage, and long-life

 filter elements makes it accessible for operators of varying experience levels.

Q13: What is the overall value proposition of the HCP Series?

A: The HCP Series offers:

· Reliable contamination control – achieving NAS Class 5 cleanliness

· Efficient water removal – removing both emulsified and free water

· Protection of critical equipment – reducing wear and preventing water-related damage

· Extended oil life – preserving oil quality and reducing replacement frequency

· Reduced downtime – through reliable, continuous operation

· Low operator intervention – with automatic drainage and long-life elements

· Cost-effective performance – low energy consumption and reduced consumable costs

· Broad industry applicability – serving power, metallurgy, petrochemical, and manufacturing sectors

Q14: Can the HCP Series be used for oils other than turbine oil?

A: Yes. While specifically designed for turbine oil, the HCP Series is also highly effective for hydraulic oil, 

lubricating oil, and various other industrial oils. For specific fluid compatibility, please consult our 

technical team with your application details.

Q15: How does the HCP Series compare to traditional vacuum dehydration methods?

A: Unlike vacuum dehydrators that use heat and vacuum to remove water, the HCP Series uses physical

 coalescing and separating technology without heating the oil. This preserves the oil's physical and

 chemical properties, prevents thermal degradation, and typically consumes less energy—making 

it ideal for applications where oil quality preservation is paramount.

Summary

The HCP series offers a reliable, cost-effective solution for maintaining oil cleanliness and dryness in

 critical industrial 

systems. By combining high-precision filtration with efficient coalescence dehydration, it protects equipment,

 reduces downtime, and extends oil life—all with minimal operator intervention.
