PLCFC Control System

Plug & Play System to Control Compressed Air Use in Blow-off and Cooling to Conserve Energy

The Nex Flow™ user-friendly PLC flow control system (PLCFC) for 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.

We can control not only solenoid valves for on-off but can control any electrical devices such as motors, fans, conveyor motors that carry the parts, etc.

Also, our systems which come complete with one sensor, can operate with up to eight sensors (not just optical, but proximity switches and other kinds of sensing devices) for a multiple of independent tasks. Each task can be programmed. Nex Flow™ can offer the service of special programming according to customer needs.

In addition, you have a choice of any one of two types of sensors –a 500 mm sensing range diffuse type (no reflector needed) or a 3000 mm sensing range reflector type – all depending on the need. Other special sensors can be supplied on request such as laser sensors.

All this comes in a simple package at almost the same cost as the competition!

The system can be programmed to suit any special application the customer may have for blow-off systems, other automation applications or it can be tied into existing automated systems.

It is easily connected for either 110V or 220V making it suitable for applications around the world. Designed for use in the industrial environments including wet ones, this rugged unit is easy to install in tight places – flexible and easy to use and adaptable.

A stainless steel Silent X-Stream Air Blade Air Knife is turned on and off automatically as the part to be dried passes under it.

PLCFC APPLICATION – Compressed air use is reduced by 70% utilizing the PLCFC. Two Air Amplifiers used to cool castings only operate when the sensor “SEES” the castings and shuts them off two seconds after the castings are cooled. No timers need to be set. Air Amplifiers cool the castings as they move along a conveyor. The sensor detects the part to turn on the amplifiers. The air turns off after 2 seconds after the castings have passed – an ideal “Plug and Play” solution to save compressed air.
