• When air flow is verified, the bed in regeneration is brought to the pre-set
regeneration temperature.
• The bed remains at the regeneration temperature until either a pre-set time
has expired or the beds outlet air temperature rises above the “Bed Break”
target value at which point the regeneration heaters are turned off and the bed
is allowed to cool for either a pre-set time period or until the bed outlet
temperature reaches the “Cool Down” target value. If the closed loop
regeneration option was purchased, then the closed loop valve will place the
cooling bed into closed loop cooling, as opposed to ambient cooling, when
the bed outlet temperature reaches the “Closed Loop” target value.
A customer adjustable option allows the beds to switch either when the regeneration cycle
completes (“Switch on Time”) or if the dew point rises above a pre-set limit (“Switch on Dew
Point”). The “Switch on Dew Point” option will also cause the beds to switch if a side has been
on-line for an adjustable amount of time.
