Click here to enlarge imageABB's new low-voltage ACS 800 drive family is the narrowest in the industry, and the compact drives are available in NEMA 1 or NEMA 12 enclosures (without de-rating). All units are designed in a bookshelf style, and units range from 6.5 inch wide for 1.5 to 150 low-Hp designs, up to freestanding high-Hp units that measure only 13.78 inches wide. The freestanding enclosures of the drives in the range from 150 – 600 Hp turn easily to fit into deep, narrow spaces, or wide, narrow spaces. Rated at supply voltages of 230V to 690V, the ACS 800 is backward compatible with ABB's previous ACS 600 family, as the parameters have the same name and scaling.

Polymer preparation system
A new dry polymer preparation system from Severn Trent Services features an air driven feed that helps lower maintenance by keeping the dry and wet parts of the system separated. The Semblex Model Polymax® DL "In-Tank" Dry Polymer Preparation Systems are designed to mix, dilute and age large volumes of polymer solution from dry polymer concentrate. Advantages include complete initial wetting/dilution with minimal operator attention and lower operating costs.
