One of the major challenges for the company was to reduce energy costs with the use of compressed air for general production cleaning. The implementation of the Nederman high vacuum system created a reduction of 89.88MWh / year and the return on investment was less than three years.

 

It was in 2013 that for the first time the unit of Owens Corning Brazil, located in Rio Claro – Sao Paulo, contacted Nederman in search of a solution for the general cleaning of the glass fiber production line. At the time, the idea was to eliminate the old method of sweeping and compressed air, which in addition to consuming a lot of electrical energy and time from employees, was not effective enough.

Faced with demand and after a careful analysis of the real needs in partnership with Owens Corning's energy projects team, Nederman developed and implemented a central vacuum cleaning system using the L-PAK 250 and E-PAK 500. This, according to TPM coordinator Reinaldo Schlittler, who was responsible for the implementation at the time, yielded savings and had a payback calculated in 2.64 years, considering the cost of equipment, infrastructure and manpower for installation. "The reduction was 92,145.6 KWh / year to 2,268 KWh / year, that is, we had 89.88MWh / year savings in energy consumption.” 

Reinaldo praised Nederman's high vacuum system, in addition to meeting project expectations with a significant reduction in energy consumption and payback of less than 3 years it also improves the day-to-day work of the team. This is due to the improvement in the cleaning process of the workspace and equipment, which allows the operator to spend less time on cleaning and more time on production.  

All accessories used in the operation of Owens Corning are already standard parts of the system, but all consumables, such as filter elements, are purchased directly from Nederman, which also offers all support through its own Technical Assistance team.

"When I started working with Owens Corning I soon realized that it was a company that sought solutions for the use of electricity in a more intelligent way. This is in line with one of the promises of Nederman, which is to offer the market eco-efficient solutions that take care of productivity, people and the planet. 

Another feature always prioritized and realized was Owens Corning's demand for service agility. We understand that our response time must be fast and accurate, because once the systems are installed, the results in productivity and economy are crucial for a sustainable production for our customers. ",
commented Dorivaldo Oliveira, sales coordinator of Nederman Brazil, with more than 10 years of experience in the segment.

How the system works, step by step:

1. By means of the cleaning devices, the glass fibers resulting from the company's production process are extracted from the equipment and the manufacturing workspace;
2. The material passes through the flap valve of the system, which has the function of opening and closing the vacuum;
3. Then, the particles pass through the high vacuum piping, which has the function of transporting them to the Central Unit;
4. In the Central Unit, through Nederman technology, the fibers are separated, filtered and stored for future disposal.
