Deep Standby
Deep Standby Mode
At Bystronic, a key focus is minimizing the energy consumption of our machines and systems. Although our deep standby mode might appear to be a minor feature, it offers substantial energy savings for our customers.
Conventionally, in standard standby mode, laser cutting machines need active cooling, which mandates the operation of the chiller. Historically, the chiller lacked an energy-saving feature and consumed several kilowatts of power even in standby mode, depending on the chiller type. This results in significant energy waste when the machine is not in use.
The deep standby mode adjusts the laser to a condition where active cooling is unnecessary, allowing the machine control to deactivate the chiller.
This feature is ideal for extended pauses, such as lunch breaks or automatic shutdowns following the final cutting process in an unattended night shift. However, it is unsuitable for brief interruptions like table exchanges or nozzle replacements, as restarting the machine requires some time.
In order to put this into practice, here is a calculation example:
A customer operates five days a week with two shifts per day, but leaves the machine running during nights and weekends. With activated deep standby function, the machine spends 88 hours per week in deep standby, leading to an energy saving of ~1000 kWh per week.
If the customer operates the machine 24/7 in fully automated mode, no energy savings are possible in this scenario as the machine is continuously in use.
