Preparations to be Made before Pelletizer
PR350H Installation.
PLEASE NOTE:
The customer is responsible for making the necessary preparations before the
pelletizer is installed, such preparations to include the items listed below.
By ticking off the box to the left of each item, the customer confirms that the actual
item has been carried out properly.
As soon as the preparations for the pelletizer installation have been completed, the
customer shall sign this form and return it to IceTech by telefax.
IMPORTANT!! The Pelletizer must be placed in a well ventilated area. The presence of
sufficient ventilation and a CO2 detector is recommended to avoid high concentrations of
CO2.
Installation of a CO
2
tank, filled up with CO
2
. The following specifications are observed:
• The water content of the CO
2
does not exceed 35 ppm and is not less than 5 ppm – or
equivalent to a dewpoint temperature between -66°C and -51°C (-86.8°F and -59.8°F).
• The liquid CO
2
supply is completely free of oil and has a purity of min. 99.9%.
• The pelletizer require inlet liquid CO2 pressure between 16-22 bar (232-319 psi). The
inlet pressure has to be consistent with +/- 0,5 bar: An example: the inlet can provide
17 bar, then it can be accepted, that the pressure can variate between min. 16,5 bar and
max. 17,5 bar. If this parameter not can be obtained, it’s recommended that a buffer
tank is installed, to secure a consistent pressure to the pelletizer.
• The flow from the CO
2
tank is min. 1050 kg/h (2315 lbs/h).
• If a buffertank is installed the maximum distance from the Pelletizer is 3 meter.
Please note that the CO
2
tank capacity must always be in proportion to the actual dry ice
pellet production rate!
If there are more machines installed on the same CO
2
pipeline, precaution has to be taken,
in form of a bigger internal CO
2
pipe diameter, in order to secure the minimum flow rate to
the pelletizer.
