We recently shipped a high-capacity dry ice production and cleaning system to a client in South Korea. The order included a robust 500kg/h dry ice pelletizer and a dry ice blasting machine, configured to meet specific local power standards and cleaning requirements. This case study provides a technical breakdown of the solution we delivered.
Based on our 14+ years of experience in industrial dry ice equipment, this Korean engagement highlights two critical aspects of serving international clients: power standard customization and versatile cleaning configurations. Korean factories typically operate on a 60Hz power frequency (similar to North America), as opposed to the 50Hz standard used in China and Europe. Adapting our equipment to this requirement was a key part of our engineering scope.
The Solution: Customized Dry Ice Equipment
The client received a turnkey solution comprising a high-output dry ice pelletizer and a flexible blasting machine. Both units were engineered for the Korean market, addressing specific voltage and frequency requirements.
500kg/h Dry Ice Pelletizer: Powering Continuous Production
The core of the system is a powerful dry ice pelletizer with a production capacity of 500-550 kg/hour. This machine is designed for industrial-scale operations, ensuring a stable supply of dry ice for cleaning tasks.
- High Efficiency Conversion: Transforms liquid CO₂ into solid dry ice with a density of 1550 kg/m³, achieving a liquid-to-solid conversion ratio of over 42%. This efficiency is crucial for minimizing CO₂ waste and operational costs.
- 60Hz Power Standard: Customized to operate on 380V, 60Hz, 3-phase power, which is the standard industrial power frequency in South Korea. This required modifications to the motor and inverter systems to ensure optimal performance at a higher frequency than the 50Hz standard.
- Multi-Mold Versatility: Equipped with three different molds (3mm, 16mm, 19mm), the pelletizer can produce dry ice in various sizes to suit a wide range of cleaning applications.
- Robust Construction: With a weight of 1650 kg and dimensions of 178 × 135 × 180 cm, the machine is built to withstand the demands of continuous industrial operation.
Portable Dry Ice Blasting Machine: Flexibility on the Shop Floor
To complement the high-output pelletizer, the client selected a portable dry ice blasting machine with a 30kg hopper capacity. This unit provides the flexibility needed to move cleaning operations directly to the equipment that needs maintenance.
- Adjustable Dosage: Features a variable dry ice dosage control from 0 to 3 kg/min, allowing operators to fine-tune the cleaning intensity based on the substrate and contamination level.
- Wide Pressure Range: Operates efficiently with an air supply pressure of 5-10 bar and a compressed air flow of 2-3 m³/min, making it compatible with standard factory air systems.
- Lightweight and Maneuverable: At just 65 kg with dimensions of 60 × 40 × 70 cm, the blasting machine is highly portable. It can be easily moved to different production lines or maintenance areas without requiring disassembly of the target equipment.
- 220V 60Hz Single-Phase Power: Configured to run on standard 220-240V AC, 60Hz, 1-phase power (3 amps), which is the common standard for portable tools in Korean workshops. This eliminates the need for special power connections.

The Synergy of Pellet Production and Portable Cleaning
The combination of a high-capacity pelletizer and a portable blaster is a strategic choice for clients with continuous cleaning needs. Here’s how this system works together:
- On-Demand Supply: The 500kg/h pelletizer ensures a continuous, in-house supply of dry ice, eliminating dependence on external suppliers and the associated logistics costs and delays.
- Multi-Size Adaptability: The three-mold configuration (3mm, 16mm, 19mm) allows the client to produce the optimal pellet size for each cleaning task. For example, 3mm pellets can be used for delicate cleaning of small components, while 19mm pellets can be used for heavy-duty scale removal.
- Targeted Application: The portable blaster brings the cleaning power directly to the equipment, enabling in-place cleaning without disassembly. This is particularly valuable for large, stationary machinery or production lines where disassembly would be impractical.
- Scalable Workflow: The high production capacity of the pelletizer can support multiple cleaning stations or operators using portable blasters simultaneously, providing a scalable solution for expanding operations.
Why Customization Matters: The 60Hz Advantage
A critical engineering detail for this project was adapting the equipment to 60Hz power. While 50Hz is the global standard used in most countries, Korea (along with North America and parts of Southeast Asia) operates on a 60Hz grid. This affects several components:
- Motor Speeds: Induction motors run at slightly higher synchronous speeds on 60Hz (e.g., 1800 RPM vs. 1500 RPM for a 4-pole motor). Our engineers adjusted the motor specifications to maintain the required torque and output characteristics at these higher speeds.
- Inverter and Controls: The frequency inverters used in our pelletizer are programmed to operate efficiently at 60Hz, ensuring precise motor control and energy savings.
- Power Supply Compatibility: The portable blaster’s 220V 60Hz single-phase power requirement is perfectly aligned with standard Korean workshop outlets, making it a true “plug-and-play” solution.
