Model MIT-8X Tube brushing machine is a upgraded 2nd generation product base on rotating flexible steel rod. By using a microprocessor to control VSD, the machine can change rotating speed, or automatic rotate at forward or reverse direction. Simple and efficient tube brushing can be operated by single person. It is suitable for tube diameter range 6.4~101.6mm, such as the tubes in condenser, evaporator, absorber, heat exchanger, etc. of chillers, boilers or air compressors.

Working Mechanism

Model MIT-8X is equipped with various sizes of flexible rotating rods and brushes to suit for tubes with various inner diameters. The brushing machine’s motor drives the flexible rod rotates at high speed in the waterproof nylon tube, meanwhile supply water through the tube to the brush at end of rod. Flexible rod rotation is controlled by foot switch. When the brush rotating on the scaling on tube inner surface, loosed scaling is brushed off and brought away by water flow.
