This unit has an onboard PLC which allows site shutdowns to be connected directly to the unit.  With our custom programming we can annunciate the individual shutdowns on the VFD HMI.  Custom logic is available to suit each application.  We also have onboard PID control which allows the end user to set a desired set point and the unit will automatically maintain the set point via the external feedback signal.  We can also integrate this unit with external controllers to ensure the proper output air flow rate is achieved for efficient operation.

These units can be used on combustion air blowers or fans of any size or model.  Sizing of the units to be based on motor horsepower.
