Medium voltage (2400V – 7200V) and H.V. (13,800V) variable frequency drive systems
Siemens-Robicon Large Drives Division (formerly ASI Robicon) is the recognized world-wide leader in medium voltage variable frequency technology featuring the Perfect Harmony series of drives for large induction and synchronous motors. Siemens has the largest installed base of M.V. drives. Applications for drives include slurry and tailings pumps and other process water pumps and large process air/gas fans for the iron mining and ore processing industry. Benefits include energy savings, improved control, and reduced maintenance (wear) on slurry/tailings pump applications and dirty air/gas fan applications. Applications in the utility industry include forced draft (FD), induced draft (ID), primary air (PA), and booster fans on power boilers, boiler feed pumps (BFPs), circulating water (CW) pumps, and condensate pumps. Benefits include increased reduced auxiliary bus load for more station availability, improved heat rate, and improved control of the various processes within the utility cycle. The Harmony, and the recently introduced MicroHarmony with the smallest footprint of M.V. drives in the industry, features the Advanced Cell Bypass and the ProToPS process tolerant protection strategy to give the Robicon Harmony unparalleled drive reliability. The Harmony cell-based modular technology also provides an inherent soft-start feature which protects motors and driven equipment on start-up. The Harmony has the reputation as the world’s most versatile M.V. drive and is compatible with existing motors –regardless of age, brand, and voltage. The Harmony topology requires no input or output filters and improves motor operating power factor to near unity for induction motors.
AirStream Systems

Large fan rotor performance upgrades for energy, capacity, and wear enhancement
There are inherent inefficiencies of large process air/gas fans….often times the fan operating efficiency is far from the fan test block efficiency….this is due to mismatches between the "system" resistance curve and the fan performance curve... (poor aerodynamic inlet duct design can also be a contributor to poor fan performance)... centrifugal fans cannot compensate for these mismatches and the fan therefore operates to the left or right of the design system resistance curve - well below the optimum (or test block) efficiency of the fan.... AirSteam Systems is a fan consulting company with fabrication capabilities which specializes in upgrading existing fans... the benefits of an upgraded fan are greater performance - reduced energy consumption, increased flow capacity, and reduced wear characteristics on dirty gas/air applications... the typical (preferred) approach of AirStream is a turnkey project which they can fully guarantee the enhanced performance of the retrofit fan wheel into an existing system.
