Liquid-2-Pellet (L2P) vs. Traditional Dry Ice Blasting

Choosing the right dry ice blasting solution can have a lasting impact on your operational efficiency, maintenance costs, and overall sustainability. Here, we break down the differences between conventional dry ice blasting machines that rely on pre-made pellets and our Liquid-to-Pellet (L2P) technology, which produces dry ice on-demand directly from liquid CO₂.

L2P Technology (CoolBlast Machines):

  • On-Demand Dry Ice: Produce fresh dry ice pellets on-site as needed, eliminating storage and sublimation losses.

  • Consistent Quality: Always use freshly made, top-quality pellets for optimal cleaning performance.

  • Reduced Waste: No idle pellets sublimating before you use them.

  • Minimal Downtime: Quickly adjust dry ice production to match your cleaning schedule—no waiting for deliveries.

Typical running costs

34kg CO₂ Bottle x 0.75 (to exclude 25% gas fraction) = 25.5kg liquid CO₂

25.5kg liquid CO₂ @ £63.59 = £2.49 per kg

SJ-10 average CO₂ consumption per hour = 12kg

Cost per hour = £29.88

Traditional Dry Ice Blasting Machines (Pre-Made Pellets):

  • Pellet Deliveries Required: Rely on scheduled deliveries of pre-manufactured dry ice pellets.

  • Storage Challenges: Pellets must be stored in insulated containers; sublimation leads to waste and recurring costs.

  • Inflexible Supply: If you run out mid-task, you must wait for the next delivery or pay premium for urgent orders.

  • Inconsistent Pellet Quality: Depending on supplier and delivery conditions, pellet quality can vary.

Typical running costs

50kg dry ice pellets x 0.92 (to allow for 8% sublimation) = 46kg of usable dry ice

46kg dry ice pellets (Dry Ice Supply) @ £120.83 = £2.62kg

Average dry ice consumption per hour of SJ-10 comparable machines = 20kg

Cost per hour = £52.40

SJ-10 specification and CO2 usage

  • Compressed air consumption - 0.3 to 2 m3/min (11 to 71 CFM)

  • Compressed air operating pressure - 5 to 16 bar (72 to 232 psi)

  • Liquid CO2 consumption - 0.1 to 0.3 kg/min

SJ-25 specifications and CO2 usage

  • Compressed air consumption - 1 to 6 m3/min (35 to 212 CFM)

  • Compressed air operating pressure - 5 to 16 bar (72 to 232 psi)

  • Liquid CO2 consumption - 0.4 to 1.5 kg/min

Taking an average CO2 consumption for each machine they would use the following amount of CO2 per hour. 

  • SJ-10 @ 0.2 kg/min = 12 kgs an hour

  • SJ-25 @ 0.7 kg /min = 42 kgs an hour
