Fully Automatic HVAC Equipment Return Bender Machine
1. Introduction
Return Bender is a key equipment for return bender production. The return
bender machine is used to open, straighten, cut and bend coil copper pipe
into return bend, mainly used for production of air-condition condenser and
evaporator, water heater, etc. This HVAC equipment is working at automatic mode.
2. Working Principle
The return bender connects two legs of hairpin bender by brazing process
for heat exchanger coil production. The return bender machine is of high
efficiency. It has 3pcs/cycle and 5ps/cylce type according to different tube size.
The return U tube bending machine is a fully automatic machine.
