As the exhibitors from Lehmann-UMT inform, viruses, yeasts, fungi and bacteria cause and increase skin disease, allergies and unpleasant odors. The input of air through the micro-aerator is said to stabilize the coolant and therefore increase the quality. As is explained, by means of special ceramic aeration plates, ultrafine air bubbles float through the coolant, re-enriching it with fresh oxygen. The floating air bubbles carry the external oil and ultrafine particles in solution to the surface, from where they can be removed. According to the German company, unpleasant odors disappear, skin diseases among employees decrease, the bio balance of the coolant is re-established, and the lifetime of the tools and machines is prolonged. The technical parameters of the device given by the manufacturers include a tank size of up to 300 l, a depth of immersion of up to 750 mm, and a voltage of 230V/50Hz/5W. Also specified is an operating temperature of 55°C, an operational range of 4 to 12 pH, an air line to the aeration body of 3 m, and a weight of 2.4 kg.
Micro-aerator maintains bio balance in the cooling lubricant
The service life of coolants is considerably reduced by lack of oxygen, foreign oils and ultrafine particles. The input of air through Lehmann-UMT micro-aerators is claimed to eliminate viruses and bacteria and prevent skin diseases among employees.
