10.1 Pressurisation
Rapid pressurisation of the dryer can cause pressure blows which can damage the
adsorption dryer! Adsorption dryer should be pressurised slowly through an appropriate
valve at the inlet.
During the pressurisation process the outlet valve should remain closed and the adsorption
dryer should not be operational.
Follow the pressurisation procedure:
•
Make certain that the outlet valve is closed.
•
Make certain that the adsorption dryer is not in operation. The controller electronics
should be turned off (LED interface lights are off).
•
Open the inlet valve slightly until you hear first flow noise.
•
Wait until you no longer hear flow noise.
•
Fully open the inlet valve and wait until the tower manometers indicate that both
towers are pressurised to the operating pressure.
10.2 Opening Outlet Valve
Opening of the outlet valve should be done extremely slowly especially when the system
downstream of the valve is not pressurized.
Follow the procedure:
•
Make certain that the adsorption dryer is not in operation. The controller electronics
should be turned off (LED interface lights are off).
•
Open the outlet valve slightly until you hear first flow noise.
•
Wait until you no longer hear flow noise.
•
Fully open the outlet valve.
