Even though more and more machines are used in processing, manual procedures still need to be carried out for checking and sorting in many sorting facilities. Depending on the type of material to be sorted, this may lead to the pollution of the inhaled air, e.g., by germs or viruses. To improve working conditions and guarantee occupational health and safety, Schulz & Berger is proposing effective and custom-fit solutions for optimum sorting booth ventilation - using either a simple air supply system, or a combination of air supply and exhaust systems.

Operating principle

supply Air systems

During ventilation in the air supply mode only, the supply air fan takes in a volume of fresh air which is adjusted to the number of workstations. The treatment of the outside air is performed by an air-conditioning device that is tailored to the respective application case.

Cleaned and temperature-controlled outside air is conducted via a galvanized pipeline system to supply air elements or, optionally, to simple air displacement diffusors. A specific mode of air conduction helps to create workplaces at which the microorganism concentration in the breathing air is significantly reduced. Operation with excessive supply air and the slight overpressure this creates inside the booth largely prevent the ingress of contaminated air from the workshop hall.

Supply and exhaust air systems

For sorting booth ventilation using a combined supply and exhaust air system, the air conditioner installed will have an air intake unit and an exhaust air unit. The processing of the supply air is done by analogy with a pure air supply system but offers an additional option to use the exhaust air returned for heating up or cooling down fresh air by means of a heat exchanger.

The strict separation of supply air and exhaust air flows absolutely excludes any exchange of germs. Exhaust air is taken in beneath the sorting belt conveyors immediately at the workstations.
