Close Control - Constant Output (Microvap
LMD)
Laboratories are typically small spaces with frequent and
sometimes continuous fresh air change, where humidity must
be maintained within close tolerances. Brief 'blips' in
humidity levels associated with the Humidifier feed and
drain cycles are usually unacceptable. To meet these exacting
demands we have developed Microvap LMD, a range of twin
cylinder units that will deliver and maintain humidification
instantly modulated to match changes in demand.
Microvap LMD combines Varivap proportional
control with the new VOS-6 system and additional special
software routines. When operating normally, each cylinder
delivers 50% of humidity demand. Whenever one cylinder needs
to feed or drain, the other cylinder instantly increase
output to compensate. The result, a modulating close tolerance
uninterrupted steam supply.
Signals
The new range of Microvaps will respond to all common control
signals which can be simply connected to the Microvap controller.
There is signal isolation and the connection is not polarity
sensitive which helps facilitate installation.
