PERFORMANCE
Temperature settings indicate the average air
temperature at the end of the delivery hose
Ambient, 34°C, 37°C, 40°C, 43°C or 46°C
Note: The air temperature around the patient is affected by the ambient air
temperature, the warming blanket type and the use of an insulating blanket
placed on top of the warming blanket.
Temperature accuracy of delivered air, except for the
ambient temperature setting
+ 2°C with delivery hose cover.
Not specified without delivery hose cover.
Environmental conditions required to achieve the
specified temperature accuracy
20°C to 22°C, 30% to 70% relative humidity, non-condensing
Time required to attain the specified temperature
accuracy of delivered air following a change in
temperature setting
5 minutes
SAFETY SYSTEMS
Dual temperature limit thermostats
Either of two independent 53°C self-resetting thermostats removes power
from the CWS4000 if the delivered air exceeds a preset limit temperature.
Heater temperature limit devices
A 98°C thermal fuse and 104°C self-resetting thermostat protect the filter
from excessive temperatures.
Temperature limit alarm
Continuous temperature monitoring guarantees that the temperature of the
delivered air maintains its specified accuracy.
Control system failure alarm
Continuous self-monitoring by the control system ensures that it always
functions predictably.
