E. Air Treatment Centre
Provide redundant medical air treatment systems that contain CRN registered components including desiccant
dryers, lters, and puriers sized for peak calculated demand. Dew point and carbon monoxide monitoring Medical
Air Treatment shall include:
1. Drying and purication units shall dry air to a dew point to -40°C at 350 kPa (-40°F at 50 psi).
Refrigerant dryers are not acceptable.
2. Dryer purge ow control through an integral dew point based purge control system. Purge
controllers using desiccant temperature are not acceptable. Drying units shall provide a
numerical indication of the outlet dew point and initiate an alarm when the outlet dew
point exceeds the manufacturer’s pre-set limit. Desiccant dryers shall have alarm sensors
for tower switching failure.
3. Mounted pre-lter with corrosion-resistant housing rated for 0.01 µ with automatic drain
and element change indicator at the inlet to each dryer.
4. Final line lters rated for 0.1 particulate after lter with element change indicators,
duplexed nal line regulators, and duplexed safety relief valves shall be factory mounted and
piped at the outlet of each dryer.
5. An activated carbon nal lter shall be installed upstream of the line pressure regulators to
remove volatile organic compounds and reduce odor levels.
