PLC based air knife controller
Nex Flow Air Products Corp.
compressed air is truly advanced and uses the most modern technology
available today and can be used as a standalone unit or interfaced with
other automated systems. The PLCFC is a PLC based system - not just
a simple timer. It is not just a simple, often overpriced sensor and timer.
The PLCFC combines a photo electric sensor to turn on the air when the
target passes the sensor and to turn off the air when it leaves the sensor. (The unit is set to have a 2 second delay after it leaves the sensor but turns on instantaneously when it sees the target). We can supply an optional timer if the customer wants to set the unit to turn off based on time rather than using the sensor to turn it off.
Unlike many competitive units, which only offer a simple on-off with timer, it does not really optimize the air use if the timer is set wrong and leaves the system running far longer than necessary.
