Project Background
A thermal power plant in Thailand uses phosphate ester fire-resistant oil for EHC hydraulic control system. After years of operation, the oil suffered hydrolysis, rising acid value and tiny particle contamination, which easily caused servo valve stuck and system failure. The client needed professional stainless steel fire-proof oil purification equipment to restore oil indexes.
Client Challenges
- Ordinary carbon steel purifier will accelerate phosphate ester hydrolysis and aggravate oil deterioration
- Oil acid value increased, corroding seals and precision servo valves
- Tiny particles cause valve jamming, threatening power system stable operation
- Frequent oil replacement leads to high operation cost
Custom Solution
We recommended TYF Series Phosphate-ester Fire-proof Oil Purifier with full 304 stainless steel wetted parts. Equipped with vacuum dehydration, fine filtration and optional ion exchange resin module, it specially solves hydrolysis, acid rise and particle contamination of fire-resistant oil, avoiding secondary pollution caused by carbon steel equipment.
Project Implementation
All fluid contact parts are made of stainless steel to ensure material compatibility with phosphate ester. We completed factory assembly, vacuum test and purification performance test. The equipment was packed in moisture-proof export wooden case and delivered by sea. Professional technical guidance was provided for on-site commissioning and acid value reduction treatment.
Project Results (Quantified)
- Oil moisture reduced to ≤100PPM, particle cleanliness up to NAS1638 Class 5
- Oil acid value effectively controlled, hydrolysis reaction stopped
- Servo valve jamming failure completely eliminated
- Fire-resistant oil service life extended by 2 times, saving huge oil replacement cost

Project FAQ
Q1: Why cannot use ordinary oil purifier for phosphate ester oil?
A: Carbon steel will catalyze oil hydrolysis, leading to faster acid value rise. Only full stainless steel equipment is compatible.
Q2: How to reduce the acid value of deteriorated fire-resistant oil?
A: Match ion exchange resin module to adsorb acidic substances and inhibit hydrolysis.
Q3: Can the equipment be used for long-term online maintenance?
A: Yes, it supports daily circulating purification to keep oil indexes stable.
Q4: Does purification affect oil fire resistance?
A: Physical treatment only removes pollutants, no impact on fire-proof performance.
Q5: What is the maintenance cycle of resin module?
A: Replace according to oil pollution degree, with low long-term cost.
