HSI Controls for Multistage Centrifugal Blowers

From the simplest across the line starter with an ammeter to a complex PLC controlled variable frequency drive application, HSI has the expertise to provide the blower control package needed for any multistage centrifugal blower installation.
We have developed a line of standard control packages from which to choose. For example, the HSI 2100 is PLC based with full touch screen interface and provides monitoring, shut down and trending functions for vibration, bearing temperature, blower surge, and motor overload. The standard unit has three extra inputs that can accommodate a variety of data such as flow,pressure, temperature and

dissolved oxygen. The HSI 2100 can modulate automated throttling valves, variable frequency drives and blow off valves. The unit can be programmed to communicate with all types of plant control systems and extra cards can be added to accommodate almost any control requirement.
In addition to the HSI 2100 we have several other models with various levels of functionality all the way down to a simple calibrated analog ammeter. We can also design and manufacture systems using any brand of equipment specified by the customer.
