SRC Wireless Remote Control

The power generation of vacuum tube lifter units can be switched on and off as needed using a wireless remote control integrated into the operating unit. This can save up to 40 % on operating costs.

To prove it, vacuum specialist Schmalz compared two different vacuum tube lifter units. One of the units had a Schmalz Radio Control (SRC) wireless remote control integrated into the operating unit. This allowed the connected vacuum blower to be switched on and off as needed to suit interruptions in work. The other unit did not have this energy saving function, so vacuum generation remained in continuous operation.

The efficiency comparison of the two vacuum tube lifter units was based on the following conditions:

• Identical power consumption of the vacuum blower (4 kW)


• Average industrial electricity price of EUR 0.1255 per kWh


• CO2 emissions of 0.921 kg CO2 per kWh of power used


• Operating time of 245 work days per year

With the first lifting unit, when used for a period of one hour, the blower stays switched on continuous operation the entire time. In comparison, the tube lifter unit equipped with the SRC wireless remote control runs for only 36 minutes (as measured based on typical operation). When calculated for a work day of eight hours with two operating shifts, the energy consumption is only 38.4 kWh in comparison with 64 kWh for the machine in continuous operation. When compared over the course of a year, using the SRC wireless remote control, the user can save up to 6,272 kWh in power, which translates to a savings of around EUR 790 on operating costs (40%) and a 40% reduction in CO2 emissions, which is better for the environment.

The user benefits from the long service life of the products, reduces primary energy consumption and lowers operating costs. In addition, the user is helping to protect the environment.
