Liquid or water-cooled Indramat and Rexroth drives and servomotors are great for huge amounts of torque in small spaces, but all that condensation can wreak havoc on your Indramat and Rexroth equipment if you don’t take the proper steps to ensure against it.
Your equipment is probably contained inside of a big climate-controlled case, but the cooling unit lines are also inside of this case. As the cooling unit cools down, any sort of humidity inside of the case will condense on the cooling unit and lines, causing severe damage to your equipment if water comes into contact with the electronic parts.
Don’t open the cabinet
Cooling temperature guidelines set by Indramat and Rexroth need to be followed closely to ensure that your machinery won’t suffer from major failures due to condensation and humidity. Don’t just open a cabinet willynilly—it can allow humid air to enter the cabinet. When you close it up after maintenance and start it back up, you’ll have failures left and right. Instead, you’ll need to take steps to ensure the air outside the cabinet is the same as inside when you’re opening cabinets up for service.
Cooler units also need to be arranged inside of the cabinet so that if condensation does form, it won’t come into contact with the Indramat drive at all. No drips, drops or spray from the unit can touch the important bits inside of your Indramat Rexroth cabinet. Make sure that there’s a separation between the cooled air and the Indramat Rexroth electronic equipment inside of your cabinets. If you need to add in an airflow area for the lines, do so.
