The "Dry Ice Uniformity" is a key element in ensuring the performance of dry ice cleaning.
In practice, specific sizes and dry ice densities are required for different customer needs to avoid incomplete cleaning or damage; moreover, to ensure consistent particle size production for the best cleaning results.
In today's dry ice cleaning market, only our dry ice manufacturing machine can produce "continuously uniform-sized" dry ice pellets and blocks, with a production capacity of 1,000 kg per hour.

Dry ice is solid carbon dioxide (CO₂) with a temperature as low as -78.5°C. At room temperature, it sublimates directly into gas without leaving any moisture behind, making it one of the most widely used low-temperature media for industrial cleaning, cold chain logistics, food preservation, and event effects.
MDS is a local dry ice manufacturer in Taiwan and a technology leader in Taiwan's dry ice cleaning machine industry, with a market share of more than 80%. We independently develop dry ice cleaning machines, dry ice production machines, and dry ice storage containers. This gives us a clearer understanding than any supplier focused solely on selling dry ice: equipment cleaning performance depends directly on using the correct dry ice quality and specifications.
That is why our standards for dry ice are stricter than those of our industry peers—from the purity of the CO₂ raw material and pellet-forming pressure to the consistency of finished-product specifications, every stage is independently controlled.
The most common question before purchasing dry ice is, “Which specification do I need?” The ideal dry ice specification varies depending on its intended use. The following recommendations are based on our practical application experience:
The Preferred Choice for Industrial Precision Cleaning
Cleaning semiconductor equipment, circuit boards, optoelectronic components, and other precision components
The small pellets deliver concentrated impact and can reach fine gaps to remove residue. They sublimate instantly upon contact with the surface without damaging the substrate.
The Ideal Input for Heavy-Duty Industrial Descaling
Casting molds, rubber processing equipment, rapid removal of buildup layers, printing units, and petrochemical pipelines
Strong penetration and high stripping efficiency. Under normal conditions, it can replace traditional processes such as abrasive blasting and chemical surface pretreatment.
For Cold Chain, Logistics, and Event Applications
Fresh food delivery cold chains, low-temperature pharmaceutical and biotechnology transportation, restaurant presentation effects, and wedding or stage effects
Long-lasting cooling and convenient handling, with performance far exceeding that of ordinary ice
We are not a distributor. We manufacture and ship our products directly. Every batch of dry ice is produced at the MDS factory, with specifications and quality grades controlled throughout the process. This is particularly important for industrial customers who require consistent dry ice quality, including semiconductor plants, rubber mold factories, and food processing plants.
MDS provides dry ice production machines, dry ice cleaning machines, and dry ice storage containers. If you are evaluating the introduction of dry ice cleaning equipment, we can discuss on-site which dry ice specification delivers the best efficiency with each cleaning machine model, providing a seamless one-stop solution.
MDS equipment is developed, manufactured, and maintained in-house. Customers can receive immediate assistance whenever a problem occurs without waiting for a third-party manufacturer to respond.
Dry ice is not limited to cooling and preservation. Its applications span industrial manufacturing, food, pharmaceuticals and biotechnology, food service, events, and many other fields:
Descaling and cleaning equipment used in casting, rubber, semiconductor, electronics, plastics, molds, petrochemical, and printing industries—without equipment disassembly, chemicals, or wastewater
Uninterrupted cold chain transportation for fresh meat, seafood, ice cream, vaccines, blood, and biological specimens
Dry ice beverages, wedding fog effects, stage effects, and Halloween events
Shrink fitting of metal components, rapid freezing treatment, and sample preservation
Shrink fitting of mechanical components and rapid cooling for chemical experiments.
Dry ice naturally sublimates continuously at room temperature, with a daily loss rate of approximately 10%–30%. Proper storage not only extends its usable life but also ensures safe handling:
Store dry ice in a thick-walled Styrofoam box or professional insulated container. Fill empty spaces as much as possible—dry newspaper may be used as filler—to reduce air circulation and effectively slow sublimation.
A household freezer operates at approximately -18°C, which is far warmer than dry ice at -78.5°C. Placing dry ice in a refrigerator cannot stop sublimation and may damage the thermostat due to the extremely low temperature.
When dry ice sublimates into gas, its volume expands approximately 800 times. Never seal dry ice inside a thermos, airtight plastic container, or glass bottle, as excessive internal pressure may cause an explosion.
Areas where dry ice is stored or handled, including vehicles and indoor spaces, must be kept well ventilated to prevent elevated carbon dioxide concentrations from causing oxygen deficiency or suffocation.
Dry ice is extremely cold and can cause severe frostbite after only a few seconds of skin contact. Always wear thick cotton gloves or professional cryogenic gloves, or use tongs when handling it.
Store dry ice in a thick-walled Styrofoam box or a professional insulated container. Keep the container as full as possible to minimize air circulation. When stored properly, the daily sublimation loss is approximately 10%–30%.
No. A household freezer operates at only about -18°C, which is far warmer than dry ice at -78.5°C. It cannot stop sublimation and may also damage the refrigerator's thermostat.
No. When dry ice sublimates, its volume expands approximately 800 times. Pressure accumulating inside an airtight container may cause an explosion.
Special care is required. High CO₂ concentrations can displace oxygen in the air and cause oxygen deficiency. Vehicles, mines, and enclosed indoor spaces must be kept well ventilated.
Never touch dry ice with bare hands. Its temperature of -78.5°C can cause severe frostbite within seconds. Always use thick cotton kitchen gloves, professional cryogenic gloves, or tongs.
Whether you need on-site dry ice cleaning for a factory, fresh food delivery, or special effects for an event, MDS provides a stable supply of dry ice and professional consultation. We do more than sell dry ice—we provide a complete range of equipment and technical support to help you maximize its value.
