How much dirt does the system collect?

• The industry: Automotive / Electronic
• The initial situation: A temporary construction site was created in the company as a result of a restructuring. Since series production had to continue parallel to the renovation, a solution was needed to protect production from the dirt.
• The model: b55 3x4 above ground / with ramps
• The result: In the first four weeks, the collected amount of dirt was weighed each week. Then the rhythm of the emptying was adjusted so that after 7 and after 12 weeks there was a further evaluation. In total, the cleaning field collected 6.7 kilograms of dirt in the 12 weeks. This amount could be easily removed from the trays and did not go into production.

• The industry: Automotive
• The initial situation: The cleaning system is located in the driving area at the empties dispensing point.
• The model: b55 6x2 above ground / with ramps
• The result: Every second week the dirt was removed from the trays and weighed. It should be noted that one shift was omitted in the first two weeks and special shifts were worked in the last two weeks. This explains the larger difference in the amount of dirt. In the final report it was also calculated that with a constant dirt quantity of approx. 4.4 kg per week, the system would collect 220 kg of dirt per year. In addition, it was emphasized at this point that it thus makes a long-term contribution to technical cleanliness.

In addition to the quantitative evaluation, a qualitative dirt evaluation was also carried out. In the laboratory it was examined which material was present in which quantity in the collected dirt. Almost half of it was rubber abrasion and another third metal residues.

• The industry: Automotive
• The initial situation: The field was installed in a sluice from the outside to the inside. It represents the access to the production.
• The model: b55 4x6 at ground level
• The result: When the system was first emptied after approx. one month, it had already collected 4.3 kg of dirt. The following emptying did not take place until 3 months later. In this case 18.6 kg were removed. After a further 3 ½ months, 17.5 kg were removed. Over a period of 7 ½ months, this results in 40 kg of dirt that could not get into the building.

• The industry: Automotive
• The initial situation: The cleaning field was installed in a gate sluice. During the entire test period, approx. 294,000 passages were made there by forklifts and route trains.
• The model: b65 4x7 at ground level
• The result: The first emptying of the dirt traps took place after three weeks. At this point, 7.8 kg of dirt had already fallen through the grates into the trays. The following two emptyings took place at intervals of 5 weeks. Both evaluations resulted in 7.2 kg of dirt remaining in the system. This leads to a total amount of 22 kg of dirt, which could not get through the door into sensitive areas.

A laboratory analysis of the composition of the dirt collected, provided more detailed information. Two thirds consisted of silicon and about one fifth of metals. Wood and rubber residues were also collected in the ProfilGate® system.

• The industry: Automotive
• The initial situation: The ProfilGate® clean driving zone was installed in the entrance from the outside into the production building. There it is mainly passed by forklifts.
• The model : st55 4x4 ground level
• The result: After three weeks an emptying was carried out. The brush strips had removed 3.6 kg of dirt from the forklift wheels. It contained dust, moisture, paper, wood and even screws.

This is how the interior of the dirt traps looked after three weeks of operation before cleaning.

Here you can see the dirt bags with the amount of dirt that was collected in the respective lane. Since the vehicles drive in the middle of the cleaning area, the largest amount of dirt has been collected in the middle lanes.

• The model : st55 3x4 at ground level
• The result: 2.6 kg of dirt was removed during the first cleaning after three weeks. This contained residues of dust, moisture, paper and wood.

This is how the dirt traps looked after three weeks of operation before cleaning.

In this example, too, most of the dirt can be found in the central dirt traps. The following photo shows the exact dirt distribution by lane.

• The industry: Mechanical engineering (air conditioning systems)
• The initial situation: The brush field was installed at the entrance to the assembly area.
• The model: b55 3x2 at ground level
• The result: The emptying of the cleaning system took place at intervals of 4 weeks. On average, the ProfilGate® system collected approx. 1.4 kg of dirt in four weeks. The total amount collected during the test period was 5.4 kg.

• The industry: Mechanical engineering (air conditioning systems)
• The initial situation: The brush field was installed at the exit from the assembly area.
• The model: b55 3x2 at ground level
• The result: Every four weeks the dirt traps were emptied. The amount collected varied between about 700 g and almost 1.5 kg. A total of 3.9 kg of dirt was collected in 16 weeks.

• The industry: Mechanical engineering (air conditioning systems)
• The initial situation: The ProfilGate® cleaning system was installed directly behind the entrance from the outdoor area into the production area.
• The model: b55 4x2 at ground level
• The result: The system was emptied every 4 weeks. Over a period of 4 months, it collects a total of 4 kg of dirt that would otherwise have entered the production area.

• The industry: Automotive
• The initial situation: The installation took place internally in the transition area from one hall to the next.
• The model: b65 4x5 at ground level
• The result: After four weeks the first emptying of the dirt traps took place. At this point, the system had removed 6 kg of dirt from the operational processes.

• The industry: Food
• The initial situation: The cleaning area was installed in the pedestrian walkway between the production area and the employees' offices. It is not passed by vehicles, but only by pedestrians. For this reason, the "Go" variant was chosen, which was specially developed for this application area.
• The model: b65 3x4 Go above ground / with ramps
• The result: The system collected on average 575 g of dirt per week +/- 10 g. By removing dirt from the soles, the need for coatings was eliminated. This led to savings, as the coatings for the employee shoes no longer had to be purchased.

• The industry: Automotive
• The initial situation: The cleaning field was installed in the entrance to the company car park.
• The model: b65 4x6 at ground level
• The result: The measurement took place in liters, so that comparability with other customer evaluations is not entirely assured. The field was emptied at irregular intervals. A total of approx. 95 litres of collected dirt was documented over almost three years.

That's what the field looked like on one of the emptyings. Dirt was collected in all the dirt traps.

• The industry: Pharmaceuticals
• The initial situation: The cleaning system was installed internally in the traffic route between the warehouse and the packaging room. There it was passed by forklifts and pallet trucks. The corridor in which ProfilGate® is installed is located near the airlock and is a very clean area.
• The model: b55 3x3 above ground / with ramps
• The result: The result of the first emptying after four weeks was 530 g dirt that had collected in the system. It contained sand, soil, wood shavings, staples, screws, pens and even chewing gum packaging.
  In the field of medical products and medicines, the requirements for cleanliness and purity are extremely high. Therefore 530 g pollutants over 4 weeks are a very good quantity for this industry.

• The industry: Automotive
• The initial situation: The ProfilGate® cleaning field was installed in the building in a sluice entrance from the outside to the inside. The industrial trucks that regularly pass through are tractors, forklifts and trailers.
• The model: b65 4x4 above ground / with ramps
• The result: The emptying of the system took place every week. During this time, between 360 g and 2.4 kg were collected. The evaluation also includes the weather, so that conclusions can be drawn about the reason for the different results. In the final report, it was also positively noted that a noticeable decrease in the amount of dirt was visible down to the last field. In addition, the moisture ingress into the hall is slowed down by the grates so that no puddles occur anymore.

• The industry: Automotive
• The initial situation: The cleaning field was installed directly behind an external driveway in the building.
• The model: b65 4x6 above ground / with ramps
• The result: The dirt was removed from the trays every two weeks. In total, almost 6 kg of dirt were collected over a period of 6 weeks.

• The industry: Mechanical engineering (injection systems for diesel engines)
• The initial situation: The test field was installed at the entrance in front of a clean room. During the test period, mainly people, but also small cars, passed through there. In general, there is a very clean production in this mechanical engineering company. The cleaning field was installed in the transition from clean production to the clean room with an even higher degree of cleanliness.
• The model: k55 2x3 above ground / surrounding ramps
• The result: Despite the already very high degree of cleanliness, 158.5 g of dirt were collected during the four-week test period. It was mainly metal dust, which could be easily collected from the trays using a magnet.
