Exhaust Venting

• Any structure housing a Pelletizer must have an air circulation system.
Route the Vapor CO
•
The exhaust backpressure must be less than 1 psig (.07 bar).
•
Use a 2" (51 mm) conduit when exhaust pipe is 30 ft (9 m) or less.
•
Use a 3" (76 mm) conduit when exhaust pipe is more than 30 ft (9 m)
•
The pipe can be PVC, flexible hose, copper pipe, stainless steel pipe, or sheet metal
•
ducting.

Placement and Spacing

The Pelletizer needs to be installed on a level floor with adequate load bearing to
•
support it.
Allow a minimum of 60" (1.5 m) of space in front of the Pelletizer for pellet boxes.
•

Supply Valve Locations

A safety pressure relief valve must exist between the Pelletizer and the supply line shut
•
off valves.
The liquid and Vapor CO
•
Pelletizer within easy reach of the operator.

Electrical Power Connection

Cold Jet requires a qualified electrician to install power to the Pelletizer.
•
The Pelletizer has been pre-wired for your requested voltage and frequency.
•
You must provide the correct hard conduit and four-wire, three-phase power wiring.
•
Liquid CO Storage Tank Recommendations
2
Use a tank large enough to accept a full truckload of CO
•
A refrigerator and vaporizer (heater) are needed to balance the CO
•
pressure. Ideal storage conditions are 290 psig (19.99 bar) at 0oF (-18oC).
The refrigeration should turn on at 295 psig (20.3 bar) and turn off at 285 psig (19.7
•
bar).
The vaporizer should turn on at 270 psig (18.62 bar) and turn off at 280 psig (19.3 bar).
