Since being back in Cairns I have installed some Merlin openers onto the roller doors here and they are quiet as a mouse. Mind you the ceiling has just been replaced in the garage and now the doors are noisier as they werent reinstalled by professionals.
One thing I did notice when researching which door openers to buy, particularly electric units for roller doors, 240v units are the way to go. They do not strain as hard as the 24v units. Why the step the voltage down is beyond me when they can save the heart ache and use 240v motors.
