14. Digression: Function principles
Prefiltration
99,9999 % efficiency of removal of particles and liquids down to 0,01 µm
Oil down to 0,01mg/m³
float drain as standard

15. Digression: Function principles
Adsorption
Air flows through the vessel from bottom to top. The desiccant adsorbs the moisture from the compressed air down to a -25/-40U/-70 °C pressure dew point.

16. Digression: Function principles
Desorption = Regeneration:
The blow-off valve opens and via a calibrated orifice the expanding air carries the moisture to the atmosphere.

17. Digression: Function principles
Re-Pressurisation The blow-off valve closes and via the orifice a build-up of pressure takes place.
Stand-by Until the switch between the vessels: Once again adsorption phase and repeating cycle.

18. Digression: Function principles
After-filter at outlet:
% efficiency of particle removal down to 1 µm
Hold back of dessiccant abrasion
Manual drain

19. Digression: Function principles
Cycle times (fixed mode)
Total cycle time 10 min
Adsorption time 5 min
Desorption time 4 min
Re-pressurisation time 1 min

25. Value Proposition

26. Benefit no. 1
leakage minimised unit
inlet valve-combination with single-acting valves
outlet valve-combination with non return valves
low number of threaded connections
low number of seals

27. Benefit no. 2
separately operated main-valves
clear flow-paths through the dryer at any time
process reliability

28. The competition
The position of switching valves, used by many competitors, is functionally unsafe!

29. high-grade support base
Benefit no. 3
high-grade support base
Extremely robust
Even flow distribution via perforated support base ensures full use of the desiccant surface area.
Lowers the pressure drop.
No moisture spots.
Gasket replacement without the discharge of dessiccant.

30. Almost all other competitors use simple dust sieves
The competition
Almost all other competitors use simple dust sieves
A socket below the weld seam of the vessel shell: No maintenance at the lower connections without discharging the dessiccant.
Moisture spots, a limited flow stream, a higher pressure drop are the calculated impacts.

31. Benefit no. 4
Total cycle time 10 minutes
Adsorption time 5 min
Regeneration time 4 min
Re-pressurization time 1 min
Reduced regeneration air need of 14.4 % !

32. The competition 8 min cycle time requires 15.7 %

33. Actually controlled by pressure dew point
Benefit no. 5
Actually controlled by pressure dew point
Multitronic control in combination with dew point sensor ZHM100
Dew point control for variable load situations
Change-over between the vessels just before the tolerable residual humidity is reached
Extension of the adsorption phase lowers the frequence of regeneration air need over time

34. The competition
almost all competitors use simple temperatur transmitters
arising adsorption heat as indicator for the need of vessel change-over
So-called Economy systems for pleasure yet not for a process reliable control
not feasible for multi-bank systems
not feasible for switching valve design at dryer inlet
