Phosphate Ester Vacuum Dehydration Unit Ship Oil Filtration 3000 L/hour



Series DFR fire-resistant oil purifier is especially designed for phosphate ester fire-resistant oil, this machine can treat and regenerate the degenerative fire-resistant oil, removing acid,pigment, gas, water and particles. This machine body uses the special metal materials which are compatible with fire-resistant oil,combined with technologies of vacuum dewatering, multi-stage filtration system and new adsorbent to ensure treated oil achieve new fire-resistant oil properties. Series DFR is the necessary purifying equipment for the sectors which use fire-resistant oil, it can be online working and oil-filling.



1. The tank and pipelines of the whole set are all made of stainless steel with features of portabilityfine appearance and simple operation.

2. The plant has been designed according to the vacuum adsorption theory which can remove the acid and water in the oil effectively.

3. Oil level control adopts the photoelectric way (the main components are imported from Switzerland) which can control sensitively and accurately. Oil spray will never happen.

4. The fine filter employs the special one for fire-resistant oil (imported from Italy) having a good effect on impurity control (able to reach the NAS 5-6 grade) which can satisfy customers needs perfectly.

5. Application of new absorptive materials can effectively absorb the jelly substance in oil, and eliminate the acid content in oil, as well as inhibiting the production of new acid in the system.

6. Can be controlled by PLC fully automatically as option,

7. Online operation at low temperature, 100% physical process will not cause any second pollution, environment friendly.

8. The materials and phosphate ester are of good adaptability, no leakage, and non corrosive.
