What is OptiTight®?
OptiTight® is a mechanism applicable to double-ended
DanTaet leakage protection systems for detection of small leaks.
Forward flow is sampled for a duration while return flow is cut-off, and vice versa.
Based on the recorded measurements, one of the following conclusions is reached:
- The installationen is tight
- The installationen is not tight
- The installationen is too elastic for proper measurement (air)
The cut-off sequence, during which the measurements are taken, are normally referred to
a time of day where any action required from the conclusion may be undertaken. If so desired,
the measurements can be performed several times a day.
The DanTaet systems may suppress execution of OptiTight®
if actual flow at the time is so high that an interruption will be perceptible.
Further, the execution may be forced if it has been suppressed for a number of days.
DanTaet systems for commerce and industry may also suppress execution by calendar month, or
by a control input, to which e.g. a thermal relay with outdoor temperature sensor may be attached.
This is particularly relevant when roof-mounted heaters are present in the installation.
