💡 A Word from JOBPLOY
Dain System is a small-scale manufacturing company that performs copper pipe processing and produces heat exchangers for air conditioners and chillers. As the work mainly consists of on-site production tasks such as pipe cutting, fin insertion, expansion, brazing (welding), and assembly, machine operation and adherence to safety regulations are important. Due to the nature of a small business, inter-departmental collaboration and a diligent work attitude are important, and it is an environment suitable for learning HVAC component processing technology from the basics.
