The Degasser (Armstrong) kit will need to be integrated into the production system by the
customer's piping contractor.

Exhaust System
An exhaust pipeline with an internal diameter greater than 2.5 inches is installed to facilitate
the exhaust CO
2
gas from the dry ice production process. The exhaust CO
2
gas must be vented
at a safe location outside of the building with a weatherproof outlet that prevents rainwater or
other contaminants from blocking or creating back-pressure to the pelletizer.
Additionally, the CO
2
exhaust could have a temperature as low as -27°C (-16.6°F) which may
generate condensation. Cold Jet recommends installing an Armaex insulation or similar
product to prevent this condensation from dripping down onto the machine or production
room oor.
