Dn-m series high precision oil purifier is mainly used for purification and filtration of water glycol fire-resistant hydraulic oil to restore its new oil performance and reuse.   

The company has developed the following two series of products according to the characteristics, viscosity and different user needs of water glycol oil products:

Dn-m series high-precision oil purifier is used in various fields using water glycol oil products such as machinery, metallurgy, mining, petroleum and chemical industry to restore its performance.

The filter element of this equipment is specially designed for water glycol hydraulic oil. This filter element only removes impurities and does not remove water.

● built in independent oil pump, which can continuously purify oil;

● multiple models are available, and the pump flow ranges from 6L / min of 2R type to 21l / min of 7R type;

● high filtration precision: one filtration can restore the international standard cleanliness: nas12 grade (iso21 / 18) → nas5-8 grade (iso15 / 12 ~ 17 / 14);

● equipped with suction filter screen device to protect the oil pump and shutdown device for leakage, overload and filter element saturation to protect the motor;

● indication of filter element replacement;

● it is equipped with oil pumping and filtering conversion device to facilitate both oil pumping and filtering;

● equipped with positive and negative switches to avoid the trouble of three-phase power wiring;

● adopt multi-stage precision filtering and step-by-step encryption filtering technology, with high filtering precision;

● the machine has the characteristics of advanced process design, high degree of automation, fast refueling, compact volume, light weight, flexible and convenient movement.

2、 Dnm-i series water glycol special filter oiler

Product features:

● the device is mainly used for fine filtration of water glycol oil products with high kinematic viscosity. According to the characteristics, a special filter is adopted to filter only impurities without damaging the water in the oil.

● all tanks and pipes of the whole machine are made of acid resistant and dissolution resistant stainless steel, and all metal materials are made of stainless steel (1Cr18Ni9Ti), without drip and corrosion. Beautiful appearance and convenient operation.

● high quality filter element, multi-stage filtration and step-by-step encryption, large sewage capacity, acid, alkali, high temperature resistance, good mechanical strength, long service life and convenient maintenance.

● auxiliary heating function is set to heat the oil to reduce the bottom viscosity when filtering high viscosity oil offline, so as to achieve the purpose of fine filtration.

● it can be operated online and truly unattended.

● humanized design, low noise, easy operation, long maintenance interval, low energy consumption and saving operation cost.

● it can be used for refueling and pumping of equipment. Fast filtration of solid pollutants.

● it is generally three-stage filtration, which can be specially made into multi-stage filtration according to the oil pollution.
