Similarities

Both belong to the **dry cleaning category** as defined by ESG. Unlike water or general wet cleaning methods, which involve a lengthy drying process following cleaning, they are described as a method that removes contaminants using CO₂-based cleaning media and compressed air. The ESG FAQ cites the ability to remove contaminants without causing significant damage to the molds themselves, as well as the simultaneous cleaning and drying feature, as advantages of dry ice cleaning machines. The product pages for precision dry cleaning machines also present the use of eco-friendly cleaning media, the absence of secondary pollution, and harmlessness to humans and the environment as common advantages.

Another commonality is that **the quality of the dry ice supply and air conditions are critical for both**. The ESG FAQ explains that a stable pellet supply is important when selecting equipment and states that the stability of the dry ice supply is a key factor in equipment operation. In other words, for both machines, it is not enough to simply "have a good machine body"; the cleaning media and operating conditions must also be considered.

Differences

1) Different Uses and Primary Application Fields

The ESG FAQ first summarizes that **their uses are different**. Dry ice cleaning machines are explicitly distinguished as being used for **machinery and mold cleaning**, while precision dry cleaning machines are used for **electrical and electronic fields such as deburring, PCB flux removal, and semiconductor cleaning**. ESG’s product page for precision dry cleaning machines also lists actual application areas such as deburring, PCB flux removal, semiconductor cleaning, precision hole cleaning, film cleaning, liquid crystal cleaning, precision mold cleaning, and automotive parts cleaning, indicating that they are closer to “precise process cleaning” than “strong stripping.”

2) Different Cleaning Characteristics

To quote the conclusion of the ESG FAQ verbatim, **dry ice cleaning machines are used when powerful cleaning power is required**, while **precision dry cleaning machines are used when precise cleaning is required**. In the FAQ, ESG describes dry ice cleaning machines as “first-generation cleaning machines” and precision dry cleaning machines as “equipment developed to meet the demand for more precise and sophisticated cleaning.” In other words, the difference between the two is not simply a matter of superior performance, but a **difference in the cleaning method required by the process**.

3) Air Consumption Differences

According to the ESG FAQ, the average air consumption is **approximately 3 cubic meters for dry ice washer** and **approximately 0.5 cubic meters for precision dry washer**. The detailed specifications for the EDS-PD on the product page also list the air consumption of the precision dry washer as **0.5 cubic meters**. This difference can lead to variations in compressor capacity, equipment layout, noise levels, and utility costs in the field.

4) Dry Ice Consumption Differences

The ESG FAQ explains that the precision dry washer uses **about 1/10** less dry ice on average. The EDS-PD product page also presents pellet consumption as **0–240 g/min, averaging 100 g/min**, demonstrating that it is a precision-controlled device. This represents a significant difference in terms of operating costs and cleaning condition control in precision processes.

5) The nature of noise and equipment size differs.

According to the FAQ, the noise level is described as **approx. 80dB for the precision dry cleaner** and **approx. 110dB for the dry ice cleaner**. The product page also specifies **low noise (80dB)** as a feature of the EDS-PD. The FAQ also notes that the **sizes of the two machines differ**, and the EDS-PD is actually introduced with relatively compact specifications of 350×300×400mm and 23kg. In other words, the precision dry cleaner is strongly characterized as equipment better suited for work cells, laboratories, and precision process environments.

6) The level of precision control functions differs.

Looking at the ESG product page, the precision dry cleaner EDS-PD highlights features such as **stepless particle size adjustment from 0.05 to 2mm**, **multi-stage cleaning power adjustment**, **self-cleaning function**, and **mic control/dedicated board control**. This means that these factors are more suitable for tasks where condition control is critical, such as deburring, PCB cleaning, and semiconductor cleaning, rather than simple contamination removal. On the other hand, the dry ice cleaners described in the FAQ focus on strong cleaning power and general-purpose mold and machine cleaning rather than such precise control.

* **If strong cleaning power is the priority, such as for molds, equipment, or machine contamination, choose a dry ice cleaner.**

* **If deburring, PCB flux removal, semiconductor cleaning, or cleaning of precision holes, jigs, and parts, choose a precision dry cleaner.**

In other words, rather than viewing the two types of equipment as competitors, it is more accurate to consider them as **lineups divided according to the cleaning target and process purpose.**

ESG also operates its PRODUCTs on its website by dividing them into **Precision Dry Cleaners / Powerful Cleaners / Automation Solutions**, demonstrating that the structure is not one where the same equipment is called by different names from the start.
