Success Story


ColdBox makes temperature controlled transport boxes.  They came to us looking for a way to reduce their control costs and improve system performance. > Their needs :

snow_sun Temperature Control, both heat and cool :  Temperature must be maintained within very narrow window for critical applications including pharmaceutical transport.
touch_screen_100 Touchscreen :  Allow users to adjust settings and verify performance.

GPRS/GPS Cellular Transceiver :  Used to collect temperature readings from ColdBox to document performance.  Allows settings to be controlled remotely.

When ColdBox approached us, they were using a classic PLC solution.  Between their PLC and related control equipment, their controls cost them approximately 3000 € per box.

We reduced their costs to 360 € per box, a 88% savings.

Control Costs : 3000 € Control Costs : 360 €

Equipment used : Embedded Ace 7096. With it’s built in thermocouples, we could easily monitor temperature in different sections of the ColdBoxes.  The 2 RS232 ports allowed us to communicate with both a TouchScreen (using Modbus) and a Cellular Transceiver (using custom messages).

Big Improvements


88% cost savings : From 3000 € per system down to 360 €


Reduced Installation Costs : The smaller footprint and simplified wiring allows their technicians to built systems much faster.


23% Battery Efficiency improvement : Ace was able to achieve dramatic battery efficiency improvements.  This gave them the option of reducing the batteries used in each system, or extending the range of each box.

What ColdBox says about Ace solution ?

    Changing to the Ace PLCs reduced our material and labor costs substantially, but more importantly it eliminated numerous points of failure compared to our previous operating system. The introduction of the Ace PLC is responsible for dramatically improved reliability and efficiency of our product. – CEO of ColdBox

    Programming is more flexible, quicker and easier to implement. Operation is more intuitive. Because of the more advanced flow chart programming, we were able to improve battery performance by 23%. Every aspect is better than our previous solution. Ace Automation has been totally responsive to any and all issues that have been encountered, providing solutions that are timely and customer focused. – R&D Manager

    Changing from the Classic PLC to Ace made product assembly much more efficient and reduced the space required by 90% – Manufacturing Manager

    Ace was able to implement functions that we simply weren’t able to do with the Classic PLC unit. That has greatly enhanced  remote operation of our fleet. – Fleet Operations Manager
