SMPi/SCPi Vacuum Ejector

The vacuum ejector with air-saving function saves its users up to 65 % on operating costs compared to with conventional vacuum ejectors.

The SMPi/SCPi vacuum ejector from Schmalz allows the user to optimise work processes, utilise resources more efficiently, dramatically reduce operating costs and help to protect the environment. This can be shown by comparing the efficiency of this system with that of a conventional vacuum ejector.

Integrated Air-Saving Regulation for Low Compressed Air Consumption

Here, we used a cycle time of 15 seconds. The compressed air consumption is the same for suction and blow-off of the workpiece. The most significant difference between the two vacuum ejectors is the “suction” function during the actual transportation of the workpiece. The conventional ejector must be in operation for 4.22 seconds in order to safely secure the workpiece. The Schmalz SMPi/SCPi vacuum ejector requires only 0.3 seconds of switch-on time. This is facilitated by the integrated energy saving function: It interrupts vacuum generation as soon as a safe vacuum value has been reached. Vacuum generation is switched back on only once the value exceeds the preset minimum vacuum value. The length of the “suction” function, or the time during which the vacuum generator is operational over the course of the complete cycle, lasts only 1.19 seconds per cycle time. In comparison, the conventional vacuum ejector requires 5.11 seconds per cycle. Calculated over for 245 work days per year, with 3,840 handling cycles per day and two operating shifts, the user can save around 11,000 m³ of compressed air. This translates to around 65 % less compressed air compared to a conventional vacuum ejector.

Significant Savings on Operating Costs, Better for the Environment

At an average cost of compressed air of EUR 0.05/m³, the user can save around EUR 550 annually on operating costs. Thanks to the reduction in energy consumption, the user helps to protect the environment by reducing CO2 emissions by 365 kg.

This shows that when developing new products, Schmalz focuses on advancing technology as well as developing resource-efficient solutions. The user benefits from the long service life of the products, reduces energy consumption and lowers operating costs. In addition, the user is helping to protect the environment.
