NRT Announces New Color Sorter

The ColorPlus™-R enables opaque color detection

Nashville, Tenn. – January 25, 2017 – National Recovery Technologies (NRT) has announced a new addition to the company’s product offering, the ColorPlus-R. Similar to the ColorPlus, the ColorPlus-R uses an advanced image processing system to detect materials based on color analysis and object recognition. Unique to the ColorPlus-R is the ability to color analyze opaque objects, such as black plastics.

All ColorPlus models employ transmissive detection, placing the material between the light source and the detection camera. Transmissive detection provides the strongest signal strength and accuracy. NRT In-Flight Sorting® technology, processing up to 50 million pixels per second, is able to detect and immediately target each object in flight. In addition to transmissive detection, the ColorPlus-R has added a second LED light source above the material to facilitate reflective detection. Whereas opaque materials were before only recognized as objects, the ColorPlus-R’s simultaneous use of reflective and transmissive detection makes possible color analysis.

“The real advantage to the ColorPlus-R is the ability now to recognize the color of an opaque object with extreme confidence and in a fraction of a second,” said NRT President Matthias Erdmannsdoerfer. “For example, black plastics pose a problem to our customers, particularly in Plastic Recycling Facilities where accuracy is ultimately defined by the parts per million. Black plastics absorb too much light for near infrared detection by polymer type, so with this new equipment we can effectively remove this type of contamination. Our team should be proud of yet another accomplishment that will pay dividends to our customers.”
