//Diffuse coolant emissions efficiently eliminated

The only effective solution: A combination of direct capturing and in-hall air cleaning
The emissions are identified as closely as possible to the - mostly encapsulated - work machines, and are deposited in decentralised or centralised filtration systems. The diffuse hall emissions are secreted with the residual emissions of filter devices in a central unit. Thus, the dissipated excess heat can be recovered and used to heat the supply air in the heating period. The hall air purification system supplies the production hall with fresh air, thus ensuring a balanced air management. A further advantage is that the waste heat is discharged, and therefore overheating of the hall is avoided.

Legal situation in Austria and Germany
A total limit value applies in Austria and Germany. This is the sum of the total of the liquid and gaseous emissions (based on October 2016):
Germany: < 10 mg/m³ liquid + gaseous cooling lubricant emissions
Austria: < 20 mg/m³ liquid + gaseous cooling lubricant emissions, whereby the proportion of liquid emissions must be < 1 mg/m³.

This example illustrates how demanding compliance with the limit values is:
Anyone who fills a 20 ml liquor glass to the top with cooling lubricant and distributes the contents in a room with a volume of 1,000 m³ (L x W x H = 12.5 x 10 x 8 m) has then already reached the maximum room air concentration in Austria. In this case, the value applicable in Germany has been exceeded by 100%.
