During our many visits to various can making plants around the world, customers often request our insight for methods that will reduce their energy consumption. Frankly speaking, the discussion involving how to minimize energy consumption in a can making plant intrigued us. We continued to interview and study can making plants. We noticed a common practice among many can makers is to allow their ovens to operate at full operating conditions during line stoppages. We realized this practice is a gross waste of energy that results in tens of thousands of dollars wasted each year. Our engineers quickly went to work to develop a solution to keep the machines humming yet reduce energy consumption.
International Thermal Systems is proud to introduce the NEW ITS Sleep Mode Program™. The NEW ITS Sleep Mode Program™ is a program within the PLC that is an optional feature on all ITS equipment and is available as a retrofit for ALL makes and models of Ovens and Washers. The premise behind the program is to save energy during line stoppages which saves you money. In order to achieve these savings the following will take place:
Upon activation, the ITS Sleep Mode Program™ will receive a signal from line control that there has been a line stoppage; once that signal is received a timer will start counting down to a pre-determined time. Once the time has elapsed, the program starts and three things will happen:
- Temperature Controller Set Point is lowered.
- Burner Output is Reduced.
- Recirculation & Exhaust Fan Speeds are lowered.
When engaged, the ITS Sleep Mode Program™ the following benefits will be possible:
- Oven Temperature is Reduced.
- Fuel Consumption is Reduced.
- Electrical Power Consumption is Reduced.
- Oxidizer Heat Load is Reduced.
Upon deactivation, the ITS Sleep Mode Program™ the Oven receives a signal from line control letting it know that the line is once again ready for production. Within minutes your oven will be back to normal operating conditions.
To give you a practical example of the potential savings that the ITS Sleep Mode Program™ could provide, we assumed total line stoppages of 2.4-hrs per day for 360-days per year, this allows for a 75% savings in fuel and electricity by using the ITS Sleep Mode Program™. Based on these assumptions the savings will be in the tens of thousands of dollars.
These savings were calculated for (1) Pin Oven……..Now imagine a line that contains (1) Dry-off Oven, (2) Pin Ovens and (1) IBO………..Now calculate when you have a plant with (2) lines, that is a total of (8) Ovens…..the savings are too significant to ignore, the savings are just waiting for you!
Remember that the energy savings doesn’t just stop with the ovens; if your oven is integrated with an Oxidizer you also be reduce the heat load requirements of the Oxidizer as well. The ROI on this feature is often well less than 1-year, this of course depends on your equipment’s current configuration.
Want to learn more about the impressive and innovative ITS Sleep Mode Program™? If you do please contact International Thermal Systems today, remember every day that goes by is another day of savings that are lost forever! We look forward to talking with you soon to discuss your specific application and helping you save precious dollars in operating costs.
