10 Climate Control for Camera Enclosures
10.1 Passive Cooling through autoVimation's Enclosures
Normal camera temperature limit
Extended
Temperature
range by passive
cooling
Latest tests have shown that autoVimation's patented Heat-Guide system significantly reduces the camera or laser temperature:

Where the camera temperature without enclosure and air movement has been around 23°C higher than
the ambient temperature, the camera temperature is only about 4 K above the ambient temperature if
installed in Orca or Salamander enclosures. Laser- and Feuersalamander enclosures show a similar
cooling effect – and that almost constant from 0°C to 50°C ambient temperature!

This means that autoVimation's enclosures can significantly extend the temperature range a camera can
be used in!

The cooling effect however depends on the camera used and the installation conditions, so the camera
temperature should be monitored, when operating at higher ambient temperatures!

10.2 Water Cooling and Heating
Water cooling greatly extends the temperature range of a MV camera
Technical Highlights:





Simple set-up and operation - the water cooling module on
top of the camera-enclosure is connected with up to 10m
long NBR tubes to the cooling unit, that is placed in an area
with room temperature. Functionality similar to the cooling
circuit of a motor vehicle.
autoVimation's water cooling units typically extend the
temperature range of a MV camera from 0 to 50°C to -40
to 120°C.
Automatic heating and cooling mode, since the water
temperature is drawn to the ambient temperature of the
cooling unit.
Water as cooling medium allows a more efficient heat
transport over longer distances compared with air cooling.
Compatible to Salamander, Orca Mammoth and Laser
enclosures



No cooling fluid is pumped through the enclosurethanks to our Heat-Guide system, the camera can be
cooled through the enclosure wall.
No oily compressed air inside the enclosure, that is
sometimes used for camera cooling.
Water cooling is the ideal solution for hot or cold
industrial environments, if there is a place with
moderate temperatures within a 10-15m distance of the
camera enclosure.
Self-contained Cooling Unit




Self-contained unit including pump (pumping hight up to 1,6m), fans and
radiator with a maximum cooling power of 1000W.
3 -fold safety function: permanent monitoring of camera temperature
and water flow and fan operation with emergency shut down function for
camera protection in case of any system failure.
included in delivery are 6m NBR water tubing (-35°C to +100°C operating
temperature) and 250ml coolant concentrate.
This unit can cool up to 5 camera housings depending on the
installation.
The camera is cooled through
the enclosure wall

10.3 Electrical Heating Plate
Temperature controlled heating plate for Salamander and Orca:
The temperature controlled heating plate heats the entire enclosure to max. 20°C. This way it is ensured that the
camera cannot overheat and there is no dew-point inside the enclosure. This heating plate maintains the camera
temperature typically at around +10°C even at -30°C ambient temperature. Power supply separately.
