Supply and exhaust systems for industry

During the spraying of liquid coatings or glue, solvent vapors and overspray arising. These have to be extracted, respectively be filtered. The maximum value for the ejection of solvents is governed by the air pollution control ordinance, as also the maximum allowable dust emissions. The solvent concentration is determined by the amount of air, it should not exceed 150 milligrams per m3 air. The aim is of course to work with as less as possible of solvent. The dust emissions should not exceed 5 milligrams per m3 air. This can be controlled by achieved designing of the filter system.

From about 6'000 m3 of air per hour it is worth to install a heat recovery system, which means the exhaust air will heat up the cold supply air on low outside temperatures. Generally, with a heat recovery system it is possible to save energy up to 80%.
