1) Heating current during the heating process (approx. 1-2 min. After heating
activation).
2) Mount individually on the conservator tank, no parallel mounting (see
mounting recommendations).
3) Alpha control: Status-dependent control of the heat-drying process
through humidity monitoring.
Beta controller (suffix T in the type designation): Self-learning system
with status-dependent control of the heat-drying procedure through humidity
monitoring and temperature-dependent determination of the most advanta-
geous time to perform heat-drying.
Gamma controller: System for applications with non-periodic breathing be-
havior. By monitoring the air humidity, the dehydrating cylinders are alter-
nately regenerated based on status.
