SKF’s CASM electric cylinder can reduce CO2 emissions in a wide range of industrial applications. In a recent study in India, an SKF customer replaced hydraulic lifts in a textile printing machine with two SKF CASM electric cylinders, and a decline in energy use estimated at 7 MWh per year was observed. This translates into a CO2 saving of 5,3 tons per year for one machine, using a world power grid mix CO2 factor of 0,749 kg CO2–e/kWh.
“The difference between using our old hydraulic lifting system and the SKF CASM 63 is huge when it comes to the environmental saving and impact. We no longer consume 400 litres of hydraulic oil a year,” says Niki Thakore, managing director, Indian Textile Engineers. “Also, our customers reduce energy usage, saving a total of around 750 000 dollars a month.”
“In India we replaced hydraulic lifts, but the potential CO2 emission reduction that can be achieved by replacing pneumatic systems with the CASM is immense when looking at the number of factories around the world,” says Markus Lieberherr, business development manager, SKF Industrial Automation.
Pneumatic cylinder systems are used around the world in a range of industries, especially in packaging, factory automation, food and beverage, and materials handling. The SKF CASM electric cylinder is an energy efficient electromechanical solution for replacing conventional pneumatic cylinder systems. Compressed air is typically a very inefficient way to transmit power, and systems often require constant power in order to maintain air pressure, even when the actuators are not moving. The CASM electric cylinders only require energy during movement. This allows customers to realise an energy use reduction of up to 90%. Additionally, electric cylinders are virtually maintenance free.
