Shutdown Button Options

We fit Schneider Emergency Shutdown Buttons to our units

​these are very high quality ultra reliable safety devices

which have a strong shutdown operation

however you may also require a shutdown button shroud to be fitted if your unit is being installed somewhere the shutdown button may be easily pressed, our shutdown button shrouds are made of high quality metal construction and they are also padlockable for when you are performing maintenance and require a method of ensuring that any control valves connected to your ACU2 are rendered inoperable. Your ACU2 will arrive with the shutdown button shroud fitted if ordered.
