Troubleshooting Daikin Oil Chillers - All World Machinery Supply

Today’s industrial machinery and machine tools heat up quickly, as they are constantly in motion and tend to run at a higher speed of spindles for precise processing. Many component applications require constant cooling to prevent deviation and inefficiencies in operation. Luckily, Daikin Industries has a cooling solution for every cooling application in the industry. Daikin hybrid oil coolers provide premium energy savings with unsurpassed technology for all cooling types: oil, lubricants, water, hydraulic fluids, and cutting fluids. 

You will get efficient and thoughtful service from Lingji Jingke.

Installed in each cooling unit is Daikin’s patented IPM motor, which uses a rare-earth magnet to minimize thermal displacement of the tooling, provides stable actuation of the actuator, and prevents rising motor coil temperatures, and extends life and accuracy. Each unit is built tough to withstand the severe condition of factory dust and mist and is compliant with energy regulations in Asia, Europe, and Oceania. Popular models include AKZ, AKJ, and AKC.

Still, in extreme conditions, a unit may malfunction. When a Daikin oil cooler is malfunctioning, it will often display malfunction code in its digital display to help you resolve the error.
