Lamp ON
When the projector/fixture is running, the heat from the lamp takes care of humidity, and
DEC3 runs the enclosure’s fan(s) to change its air every few seconds – ensuring minimal
temperature rise above outside ambient.
Lamp OFF
When the lamp is off, DEC3 senses temperature and humidity and controls its fan(s) and
heater(s) accordingly. When conditions are within normal bounds (between top and
bottom temperature settings and below the humidity threshold (see below), DEC3 pulses
the heater at a low level to dry the air and eliminate condensation, and runs the fans to
change the enclosure air every 30 seconds or so. We call this ‘pulse mode’, and it is the
key to preventing damaging condensation inside your equipment.
If the temperature rises above the top set limit (see below), DEC3 runs the fans to cool it
down. In cold conditions, DEC3 will run the heater as required to maintain the bottom set
temperature.
Thus, DEC3 maintains a comfortable operating temperature inside the enclosure, and
prevents damage from condensation. Users all over the world have found that Tempest
enclosures provide an optimal environment for expensive and delicate equipment, in
every climate type.
And while doing all of this, DEC3 can tell you what’s happening over your RDM network – a real
boon in larger installations.
