As one of the nation's largest robotic integrators, RobotWorx buys and sells hundreds of used robots each year. When the used robots arrive at RobotWorx, they are typically covered in grime, welding residues, paint, grease and other debris. To speed up the cleaning and refurbishing processes, RobotWorx recently replaced its traditional solvents and manual cleaning methods with a Cold Jet Aero Series dry ice blast cleaning system. As a result, RobotWorx has dramatically reduced its cleaning time per robot from an eight-hour workday to less than two hours, saving the company more than $60 in labor costs alone per robot, the company said.
The Cold Jet Aero system uses compressed air to accelerate recycled CO2 pellets at supersonic speeds through a specialized nozzle to create mini-explosions on the surface of the robots. This process removes the dirt and grime without damaging the hard surfaces of the robot or the sensitive electrical controllers, cables and wiring. Upon impact, the CO2 pellets sublimate and do not create any secondary waste product. The system has helped RobotWorx with its green initiatives by allowing RobotWorx to reduce its use of cleaning solvents by 75 percent, as well as the costs of other supplies needed to clean the robots by hand.
"Cold Jet's dry ice blast cleaning process is much faster than the tedious and time-consuming solvent alternative," said Matt Schrift, RobotWorx Shop Manager. "Unlike steam cleaning or using water, it allows us to clean electrical equipment because it doesn't leave a moisture blanket on or inside the robot. Cold Jet saves us time on the initial cleaning of the robots, which in turn speeds up the entire refurbishment process, allowing RobotWorx to prepare more robots for customers."
Today, RobotWorx has dedicated an area of its 100,000 square foot Marion, OH, headquarters to cleaning robots with the Cold Jet system. The company has also trained multiple people on how to use the system, which allows RobotWorx to clean robots as frequently as necessary. In addition to being effective in the refurbishing and remanufacturing markets, Cold Jet's non-abrasive dry ice blast cleaning systems are used for a variety of industrial cleaning processes, from casting systems to wood processing equipment.
Schrift said, "The major advantage of cleaning robots ahead of time is that they are much more attractive to buyers. If a clean robot sits in storage for too long, it has to be cleaned again, which makes having a fast and effective cleaning solution even more important."
"Our dry ice blast cleaning systems are having a significant impact on reducing cleaning times and costs for companies around the world," said Gene Cooke, President and CEO of Cold Jet, LLC. "Cleaning industrial robots presents many challenges because they are often used non-stop for years and have a combination of steel and electrical components. Our process is a non-abrasive, non-flammable and non-conductive cleaning method that is as effective at cleaning a robot's hard surfaces as it is cleaning the more fragile or delicate electrical components. We appreciate the confidence that RobotWorx has in our solution, and we look forward to helping them for many years to come."
