Product Name: DN-M SeriesWater ethylene glycol high-precision oil filter
The DN-M series high-precision oil filter is mainly used for purifying and filtering water ethylene glycol fire-resistant hydraulic oil, restoring its new oil performance and reusing it.
Our company has developed the following two series of products based on the characteristics, viscosity, and different user needs of water ethylene glycol oil:
1、 DN-M Series High Precision Oil Filter for Water Ethylene Glycol
The DN-M series high-precision oil filter is used in various fields such as machinery, metallurgy, mining, petroleum, and chemical industries that use water ethylene glycol oil products to restore their performance.
The filter element of this device is designed specifically for water ethylene glycol hydraulic oil. This filter element only removes impurities and does not remove moisture.
Product features:
Equipped with an independent oil pump, it can continuously purify oil;
Multiple models are available for selection, with pump flow rates ranging from 6L/min for 2R models to 21L/min for 7R models;
High filtration accuracy: One filtration can restore international standard cleanliness: NAS12 level (ISO21/18) → NAS5-8 level (ISO15/12~17/14);
Equipped with a suction filter device to protect the oil pump and a shutdown device for leakage, overload, and filter saturation, to protect the motor;
● Equipped with filter replacement instructions;
Equipped with pumping and filtering conversion devices, convenient for both pumping and filtering purposes;
Equipped with forward and reverse switches, eliminating the trouble of three-phase power supply wiring;
Adopting multi-level precision filtering and step-by-step encryption filtering technology, with high filtering accuracy;
The machine has advanced process design, high degree of automation, fast refueling, compact size, light weight, and flexible and convenient movement.
2、 DNM-I series water ethylene glycol special filtration refueling machine
Product features:
This device is mainly used for fine filtration of water ethylene glycol oil with high kinematic viscosity. According to its characteristics, a dedicated filter is used to filter only impurities without damaging the moisture in the oil.
All tanks and pipelines of the whole machine are made of acid resistant and dissolution resistant stainless steel material, and all metal materials are made of stainless steel (1Cr18Ni9Ti), which is leak free and corrosion-resistant. Beautiful appearance and easy operation.
High quality filter element, multi-stage filtration with step-by-step encryption, large dirt holding capacity, acid and alkali resistance, high temperature resistance, good mechanical strength, long service life, and easy maintenance.
● Equipped with auxiliary heating function, used for offline filtration of high viscosity oil to heat the oil and reduce its bottom viscosity, achieving the goal of fine filtration.
● Can run online, truly achieving unmanned operation.
Humanized design, low noise, easy operation, long maintenance intervals, low energy consumption, and cost savings in operation.
Can be used for refueling and pumping equipment. The speed of filtering out solid pollutants is fast.
Generally, it is a three-stage filtration, which can be specially made into multi-stage filtration according to the pollution situation of the oil.
