coolant care
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 ist 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. Both are available by Leiblein GmbH.
| 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 continuouisly cleaning of the medium is necessary. Mobile units are used to clean a small number of single machines. For mobile usage two types are available:

For mobile units following processes are available:

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 |
200 l 1200 l 240 l 24 h 4 x per year 4,800 l |
| Costs without a coalescence separator | Disposal of the cooling lubricant per year: 4.8 m³ x 100 EUR/m³ Cost of the concentrate (5% start) 240 l x 3 EUR/l Costs for the stoppage of production 96 h x 75 EUR Total costs |
480 EUR 720 EUR 7,200 EUR 8,400 EUR |
| With the use of the coalescence separator SPKA 600 double operational life |
Disposal of the cooling lubricant per year: 2.4 m³ x 100 EUR/m³ Costs of the concentrate (5% start) 120 l x 3 EUR/l Costs due to the stoppage of production 48 h x 75 EUR Costs of disposal for polluted oil and mud 300 l x 0.75 EUR Total costs |
240 EUR 360 EUR 3,600 EUR 225 EUR 4,425 EUR |
| Savings per year 8,400 EUR - 4,425 EUR = 3,975 EUR |
period of amortisation price coalescence separator 5,060 EUR 5,060 EUR : 3,975 EUR = 1.27 years The period of amortisation is shortened by longer running times. |
