What Are the Benefits of Our Innovative ProMoss™ Programs?


Water Conservation

Operation at higher cycles in cooling towers reduces water use diminishing your carbon footprint along with lowering water and sewer costs.



Water Reuse

Because treated process water systems no longer contain chemicals harmful to the environment, water can be used for other applications.


Energy Efficiency

Energy is conserved through scale and fouling reduction in heat transfer devices.  Fouled systems can be cleaned without invasive cleaning procedures.
