Since we introduced the first LEC in 2007, we have been working with PSM to develop new combustion technology and drive emissions down to ultra-low levels. As a result, the LEC III™ system operates with nitrogen oxide levels as low as three parts per million (ppm)! We can place the LEC III™ system as a direct replacement, as part of a larger conversion process, or by replacing specific components of existing OEM DLN1 systems.
