Maintaining clean cooling lubricants - this is how it is done Cooling lubricants are necessary for metal working / cutting. During the working foreign oils and dirt particles get into the cooling lubricants (emulsions) and pollute it. To achieve optimal results the emulsion has to be an excellent and continuously quality. One way is the regular change of the emulsion, but this is very expensive. Another way is to remove the waste substances and to clean the emulsion. This can de done by mobile units or central plants.
Foreign oils form a floating layer on the emulsion. The layer prevent the supply of oxygen into the emulsion. At the same time waste particles settle down and are used as food for bacteria. Finally the increase of anaerobic bacteria leads to acidify of emulsion. Thin it is useless and has to be changed. To avoid / reduce the expensive changes a continuously cleaning of the medium is necessary.
Mobile units are used to clean a small number of single machines. For mobile usage three types are available:
SPKA 600 with 600 l/h
SPKA 1000 with 1000 l/h
Oilex 600 with 600 l/h skimmer
Central plants are used for a large amounts of emulsion or to connect several machines. The applications are for example:
cooling lubricants for metal cutting
cooling lubricants for metal grinding
metal degreasing
precleaning of cracking units
The plants are accommodated to your special working and to your available space. central plant
For mobile units following processes are available: Separation via inclined plates
Separation by tower packings
1. Off-sucking from the surface by an effective skimmer 2. Gentle discharge of the cooling lubricant by a special pump 3. Separation of foreign oil and mud in the preseparator -> lamellas are less loaded 4. Main separation of foreign oil and mud on the lamellas 5. Thickening of the mud in the mud funnel 6. Draining of the foreign oil in the separation pipes
1. Off-sucking from the surface by an effective skimmer 2. Gentle discharge of the cooling lubricant by a special pump 3. Separation of foreign oil in the pre-separator -> tower packings are less loaded 4. Very efficient main-separation of foreign oil by tower packings 5. Draining of foreign oil at the overflow-pipe 6. Very effective separation of fine oil from prefiltered media 7. Ventilation of the cooling lubricant and degradation of the anaerobic conditions
7. Ventilating of the cooling lubricant and degradation of the anaerobic conditions

Cost-profit calculation of the purification of cooling lubricant The calculation is based on 6 machines with the following technical data:
Cooling lubricant per machine Cooling lubricant total Concentration 5% 60 l per exchange Stoppage 24h per exchange and per machine Exchange of the cooling lubricant Amount of disposal
Costs without a coalescence separator
480 EUR Disposal of the cooling lubricant per year:4.8m続 x 100 EUR/m続 Costs of the concentrate (5% start) 240l x 4 EUR/l 960 EUR Costs for the stoppage of production 96h x 100 EUR 9,600 EUR 11,040 EUR Total costs
With the use of the coalescence separator SPKA 600 double operational life
Disposal of the cooling lubricant per year:2.4m続 x 100 EUR/m続 240 EUR Costs of the concentrate (5% start) 120l x 4 EUR/l 480 EUR Costs for to the stoppage of production 48h x 100 EUR 4,800 EUR Costs of disposal for polluted oil and mud 300 l x 0.75 EUR 225 EUR Total costs 5,745 EUR
Savings per year 11,040 EUR - 5,745 EUR = 5, 295 EUR
: 200 l : 1200 l : 240 l : 24 h : 4 x per year : 4,800 l
period of amortization price coalescence separator: 5,830 EUR 5,830 EUR : 5,295 EUR = 1.10 years The period of amortization is shortened by longer running times.
A clean solution The inclined lamella coalescence separator is designed for a temperature of maximally 45 °C. A temperature resistance up to 80 °C can be realised with a special model. According to the model, 600l or 1000l of cooling lubricant can be purified per hour. The advantages of the separator at a glance:
prolongation of the exchange intervals for cooling lubricants reduction of the disposal costs for polluted oil and mud low investment costs high efficiency of the separator constant quality of the products because of clean emulsion reduced wear and tear of tools shorter stoppage periods for machines separation of foreign oil and solid substances at the same time problem-free separation of pollution from processing with graphite and grey iron reduced growth of bacteria and fungi simple operation and low in maintenance mobile use
The coalescence separator is designed for by-pass running. Low flow velocity guarantee a high degree of separation. DBGM 29620265.7
