With the improvements in hydraulic drive technology, it is always worthwhile exploring the options you have during partial modernisation of your hydraulic lift.
When considering a controller upgrade it is most likely due to age or unreliability. If the controller is 30 years old, for example, so is the rest of the equipment. The power unit is often overlooked or just given an overhaul. What is sometimes not considered is the benefits of combining that new controller with a new power unit.
A new power unit can give you improved ride comfort through closed-loop control, more efficient drive, reduced energy consumption, and improved starts per hour. It will also replace the 30 year old pump, motor and valve with the resulting guarantees on the new equipment.
