The 850-style rolling motor has become a staple across many industries for tube rolling. This push pull style motor exhibits both quality and performance, making it ideal for expanding tubes in chillers and heat exchangers.
The quality of an air motor will be determined based on manufacturing processes, design, and maintenance. In order to improve cleaning performance and tool life, it is important that the motor is designed for use in a specific application. This assures optimum performance and extended life of the motor.
Contractors and maintenance personnel agree, the current method of tube cleaning using a rotary flexible cable to clean chillers is a hassle. The cable is problematic; it breaks, the feeding mechanism jams, and the feeder needs frequent and costly repairs. Substantial downtime is encountered to repair cables and units.
There are two motor power sources that are used for expanding tubes mechanically: electric rolling motors and pneumatic rolling motors. Determining what motor to use for a job will depend on operator preference, availability of electricity or air, and the application.
