Protecting the environment is our collective responsibility.
Particulate emission control
We used our expertise in power electronics and embedded system design to develop the first ESP controls in late 2003. Now we developed of our own Calculus™ DSP controller with this controller more than 1000 successful installation done with in a 3 years time . As we strengthened our product portfolio we partnered with arguably the best name in the business, NWL that is renowned for making the most sophisticated High Frequency TR power supply (HFTR SMPS) in the world.
There are 3 areas that we work in to reduce the particulate pollutants given out by these large power plants, cement plants, sugarcane plants et al.
