LGUER series oil regeneration plant

These plants are suitable to regenerate both engine oils, including diesel engine oil and gasoline engine oil and other machinery oils such as hydraulic oil, lubricating oils etc
LGUER series machines can effectively remove colloid, oxid, acid, pitch, particles, impurities water gas in the oil.It can also restore color and transparancy in the oil.

Main specifications:

  • Two main filtering systems which can ensure LGUER works continuously by batch.
  • Environment friendly.
  • Design according to different customers’ needs including Turnkey project ;
  • Purify blended oils.
  • Law ,maintenance and operation costs
  • High regeneration rate
  • Automatic reverse wash system will extend the lifetime of filters and improve the performance of the filters.

Questions & Answers:
1) How can LGUER can run continuously?
LGUER regenerates waste oil by batch. NSH designed two main filtering systems in the LGUER which can ensure that GER work continuously by turns.
2) Can LGUET|R regenerate mixed oils?
Yes, LGUER can regenerate mixed oil including diesel engine oil, gasoline engine oil, hydraulic oil, gear oil and other industrial lubrication oil.
3)What residues or by-products can LGUER produce after regeneration?
For standard LGUER series, there are some residues or by-products. There is graphite exist in residues. The graphite is a very valuable substance, customer can extract graphite from residues by themselves. For advanced LGUER series, there are little residues or by-products coming into being during production. (Advanced LGUER series has device which can dispose residues or by-products.)
4) How to dispose residues and by-products?
For Standard LGUER series, customer can burn them or bury them. Additionally, customer can sell then to other factories as fuel.
5) Is every time’s treated oil’s performances the same?
It depends on waste oil. If each batch of waste oil’s performance is the same, the treated oil’s performance is the same
6) What is regeneration rate?
It depends on compositions of waste oil which you want to treat. If there is lots of water, impurities or other matters in waste oil, the regeneration rate is low.
7) What is treated oil?
The treated oil is base engine oil, the grade of treated oil is a bit lower than virgin oil’s.
8)What are treated oil’s applications?
The treated oil can be used as machinery’s lubrication oil, diesel engine oil or other lubrication oil. Customers can add additives to treated oil according to definite applications before reuse. Treated oil can also be used as fuel.
9)What are differences between virgin oil and treated oil?
If the waste oil’s properties (before use) are high, the treated oil’s properties are also high. Generally, the regeneration process doesn’t affect main performances of oil. Some indexes are lower than new oil’s, some indexes are the same as new ones’. (Please refer to test report)
10) Are there any chemical materials needed during processing?
Yes, there are some chemical materials needed in the process (please contact our sales, they will provide you detailed information.)
11) How long is lifetime of LGUER plant?
The life time is more than 8 years under proper operation.
12) What about the maintenance of LGUER?
The maintenance is very simple. Replace lubrication oil for vacuum pump every year. Check the filters, valves, gaskets periodically.
13) Does LGUER needs professional engineers to operate?
The operation of LGUER is very simple. Generally, two or three workers can operate it after two days’ training.
14) Does LGUER needs auxiliary equipments?
.We suggest that customer order an air compressor which is to improve efficiency of cleaning filter (customers can get it in your own market.). We also suggest that customers order LV oil purifier plant series from NSH. Because customers can use LV to remove particles, water and so on. Generally, customers store treated oil in big tank. During a storage period, there are moisture or impurities dissolved into treated oil.
15) How to install LGUER?
Customer can install LGUER according to operation manual. For LGUER product line, NSH will send engineers to customers’ work site to supervise installation. NSH also provide turnkey project for customers. NSH will establish a workshop for customers including auxiliary facilities.
16) What space does LGUER need?
For GER-1, 2, 3, 4,5, it needs about 200 square meters for operation. For GER product line, NSH engineers will design it for customers as neede.
17) How long is the delivery time?
For standard LGUER models, it needs about 50 working days’ production period in NSH factory. For LGUER product line, it needs one or two months’ design time, four months’ establishment time (including manufacture time in NSH factory then transport to customer’s work site and installation period of LGUER and auxiliary facilities ).
18)What kinds of engine oil LGUER can not regenerate?
Generally, LGUER can regenerate most engine oils. But gasoline engine oil, GER can remove colloid, oxid, acid, water, gas. But the color of treated oil is wine’s color should mix it with used hydraulic oil or low grade treatment in order to get good treatment oil’s color.
19) How long is warranty period?
The manufacturing plant Warrants the plant supplied under this specification against defects in material and workmanship under normal use and service for a period of sixteen (16) months from date of shipment or twelve(12) months after the start up of the system. SINO-NSH’s obligation under this warranty is limited to repairing or furnishing, without charge F.O.B. point of manufacture, a similar part to replace any part, which was proven to be defective within warranty period. SINO-NSH shall not in any event be held responsible for any indirect or consequential damages. The performance guarantee will be within limitations as detailed in duty & performance paragraph of this specification..
