General Installation
The vessel should provide liquid carbon dioxide at a pressure between 13–21 bar.
A 3/4” diameter cryogenic pipeline with a minimum of 200 mm cryogenic insulation is required.
The recommended flow rate is approximately 300 kg of LCO2 per hour, depending on piping quality and insulation.
The piping distance should be less than 15 meters. Ideally, 5–10 meters is preferred for better efficiency and reduced production costs.
The installation should have a maximum of 5 bends, each with no greater than a 90-degree radius.
The piping should run horizontally.
Valve and Hose Requirements
A manually operated 3/4” cryogenic ball valve must be installed within 5 meters of the pelletizer.
Yes. A 5-meter flexible supply hose is included and should be used to connect the pelletizer to the ball valve.
Safety and Compliance
The installation should be performed under the supervision of an industrial gas supplier company.
Yes. All national and regional standards and regulations for vessel and piping installation must be followed.
Pipes must be checked for:
- Debris
- Dust or sand
- Water or condensation
Contamination can damage the pelletizer and affect dry ice production.
Yes. Consult the industrial gas supplier to determine whether flushing or cleaning is necessary before startup.
Yes. Failure to follow installation requirements may void the machine warranty.
LCO2 Quality Requirements
The LCO2 supply company must confirm:
- No impurities are present
- Water content is between 5 ppm and 30 ppm
The temperature of the LCO2 entering the pelletizer directly affects:
- Dry ice output quality
- LCO2 consumption
- Production efficiency
Pelletizer Environment Requirements
The pelletizer can operate on 16 Amp, but 32 Amp (3x400V / 50Hz) is recommended for the 240 kg pelletizer.
Proper ventilation is necessary to prevent CO2 build-up around the pelletizer.
The pelletizer should be protected from:
- – Sun
- – Rain
- – Wind
The operating temperature should remain between 5°C and 40°C.
Enough space must be available to allow for servicing and maintenance. Please ask for dimension overview from Intelblast technical department

Escaping Gas and Venting
A minimum 2” hose with camlock connection must route escaping gas from the pelletizer to the outside.
The escaping CO2 gas can be dangerous to people and animals if exposed directly.
Degassing and Purging
Normally not, if:
- The piping distance is short
- Insulation is good
- The number of bends is limited
- LCO2 temperature is controlled
Yes. A blow-off ball valve connected to a T-joint is recommended to purge gas before pure LCO2 enters the pelletizer.
Yes. An automatic degas valve such as the Demaco Gas Vent can be installed.
Yes. The pelletizer includes a degas valve that automatically removes most gas entering the system.
Blow liquid/gas through a cloth for 10–15 minutes and inspect the cloth for:
- Dust
- Sand
- Debris
- Water contamination
Insulation Recommendations
Cryogenic vacuum insulation provides the best performance.
Poor insulation allows heat transfer into the piping, which can:
- Increase LCO2 consumption
- Reduce dry ice output quality
- Create gas formation before the pelletizer
Shorter distances help maintain lower LCO2 temperatures and improve production efficiency.
