A practical review of Dry Ice Energy, CryoGen, ICS, Cold Jet, Kärcher and ASCO machines, compared by CFM class.
By CoolBlast | Updated 6 November 2026
For a compact dry ice blasting setup, the Champ Turbo and Champ Vario are useful starting points, with the Champ Neo suited to lighter, detailed cleaning. Compare CryoGen's SC-12 Cube Vario as another compact option. If you need more output, compare the Champ Turbo Pro with larger systems from Cold Jet and Kärcher. For industrial work with a substantial air supply, consider the Cold Jet Aero 40FP, ASCOJET 1701, Kärcher IB 15/120 and CryoGen SC-16 Power Max Plus.
The right machine depends on what you need to remove and the compressed air you can supply. A blaster that starts at a low CFM figure may need considerably more air with a larger nozzle or higher pressure.
Every machine reviewed here takes pre-made dry ice pellets. Pellet-fed machines that crush or cut the pellets into smaller particles are included. Liquid CO₂-fed and block-only machines are outside this review. We assess the machines in dry ice mode, without added abrasive.
CoolBlast supplies Dry Ice Energy machines, so we have a commercial interest in that range. These verdicts are our assessment of published specifications and intended applications. They do not represent a hands-on test of every machine or a ranking of UK sales.
| Airflow comparison class | Machines to compare | Our suggested role |
|---|---|---|
| Class 1 — up to approximately 60 CFM | Champ Neo, Champ Turbo, Champ Vario, ICS IC 022 EVO | Detailed vehicle work, smaller components and localised maintenance |
| Class 2 — above 60 to approximately 125 CFM | Champ Turbo Pro, Cold Jet Aero2 PCS ULTRA, Kärcher IB 7/40 | More demanding mobile work, controlled production cleaning and larger hoppers |
| Class 3 — above approximately 125 CFM | Cold Jet Aero 40FP, ASCOJET 1701, Kärcher IB 15/120 | Industrial cleaning with larger nozzles and a substantial air supply |
Classes group machines by the upper published airflow figure or a stated nozzle reference. Ranges overlap. These are comparison groups, not universal compressor requirements. See the full airflow table and sources in the article.
Ranges overlap. A Class 2 or 3 machine may operate below its class band with a suitable nozzle. Cold Jet nozzle figures are quoted at 5.5 bar, while other manufacturers publish broader ranges or specific operating points. Higher pressure can increase demand. Sources: [1–10].
What is dry ice pellet blasting
Dry ice blasting uses compressed air to accelerate solid CO₂ pellets towards a surface. Impact and rapid cooling help release contamination. The dry ice then sublimates into gas, leaving the removed dirt, grease or coating to collect. It does not leave spent grit behind. [4]
Pellet size, ice feed, nozzle design and pressure all affect the result. A machine that cuts pellets into fine particles can offer useful control for intricate work, while a larger nozzle and higher airflow can help cover broader areas. A trial on the actual surface is the most useful way to assess cleaning speed and finish.
Class 1 compact machines up to approximately 60 CFM
This group suits operators who value portability and have a relatively modest air supply. It covers a wide span of capability: the smallest machine here is intended for a different workload from a Turbo or Vario running near the top of its range.
Dry Ice Energy Champ Neo
Our verdict: a practical entry point for light cleaning and intricate components.
The Neo weighs approximately 6.5 kg and takes 1.5 mm or 3 mm pellets. Its operating manual lists air demand of 150–250 L/min at 5 bar, approximately 5–9 CFM. That is a specific reference condition; confirm the supplied nozzle and current specification when choosing a compressor. [1]
We would shortlist it for occasional detailing, small parts and suitable sensitive components where a compact machine matters more than broad coverage. Electronics require the appropriate grounding and operating procedure. [1]
Its limitation is throughput. For regular underbody work or extensive contamination, compare a Turbo or Vario before choosing purely on the Neo's low air requirement.

Dry Ice Energy Champ Turbo
Our verdict: a straightforward compact option for regular mobile cleaning.
The Turbo's manufacturer datasheet lists 500–1,600 L/min, approximately 18–57 CFM, depending on pressure and nozzle. It weighs approximately 17 kg, runs pneumatically without a separate electrical supply, and has a published pressure range of 1–10 bar. [2]
We would compare it for engine bays, vehicle components and localised machinery cleaning. Its appeal is a portable setup with more scope than the smallest entry model. Ask for suitable round, flat and angled nozzle options for the work you intend to do.
The compressor remains decisive. Running the machine near its lower air requirement will not provide every nozzle and pressure combination in its range.

Dry Ice Energy Champ Vario
Our verdict: our starting recommendation when adjustable ice delivery and low weight are priorities.
The Vario combines adjustable ice dosing with an integrated pressure regulator. Its datasheet lists 300–1,500 L/min, approximately 11–53 CFM, and a weight of approximately 13 kg. It accepts 1.5–3 mm pellets and has a 3-litre hopper, with an optional extension to 6 litres. [3]
We would shortlist it for operators moving between intricate vehicle parts and suitable workshop or production cleaning. Adjustable dosing helps you tune the setup around the contamination instead of treating every job alike.
The small hopper is the main practical trade-off during extended work. Choose between Vario and Turbo after comparing gun handling, nozzle coverage and results on a representative surface, rather than assuming the larger model name guarantees faster cleaning.

ICS IC 022 EVO
Our verdict: a relevant compact alternative to compare with the Turbo and Vario.
ICS publishes airflow of 1.1 m³/min, approximately 39 CFM, depending on nozzle. The IC 022 EVO uses a two-hose system, accepts 1.5 mm and 3 mm pellets, and has a 4 kg hopper. Published weight is approximately 19 kg including the hose and gun. [4]
The manufacturer lists 8–10 bar operating pressure, so a compressor's output at that pressure matters more than its headline rating at 7 bar. UK supplier Titus Equipment lists the IC 022 in its ICS range. [4]
We would compare cleaning results, access around components and the supplied gun and nozzle package. Its published 39 CFM figure is a reference point, rather than a complete demand curve for every configuration.
Class 2 machines reaching approximately 60 to 125 CFM
These machines offer different routes to a more substantial setup. The Turbo Pro prioritises output in a portable package, the PCS ULTRA emphasises particle control, and the IB 7/40 offers a larger pellet hopper. Their airflow ranges overlap the compact class.
Dry Ice Energy Champ Turbo Pro
Our verdict: a useful step up when you want more output while keeping the blaster portable.
The Turbo Pro datasheet lists 800–3,500 L/min, approximately 28–124 CFM, depending on pressure and nozzle, with a pressure range of 1–14 bar. It weighs approximately 23.5 kg, has an 8-litre hopper and operates without a separate electrical supply. [5]
We would shortlist it for a mobile operator taking on more demanding vehicle or industrial cleaning, provided the air supply can support the intended setup.
Its limitation is the package around it. A compact machine capable of 14 bar still needs a compressor, hoses and air treatment rated for that duty. A 7 bar compressor cannot unlock its full pressure range.

Cold Jet Aero2 PCS ULTRA
Our verdict: a strong comparison for controlled, repeatable cleaning across different surfaces.
The PCS ULTRA takes 3 mm pellets and cuts them into 28 selectable sizes from 0.3 mm to 3 mm. It has programmable recipes and a 27 kg hopper. Cold Jet publishes 12–100 CFM at 5.5 bar, depending on nozzle, and 1.4–10 bar blast pressure. [6]
Particle size and stored settings are useful comparison points for production cleaning.
At approximately 121 kg empty, loading needs consideration. The 12 CFM figure describes a low-flow nozzle condition. Request a current UK quotation through Cold Jet. [6][11]
Kärcher IB 7/40
Our verdict: worth comparing for workshop and factory work where hopper capacity matters.
Kärcher's UK specification lists 0.5–3.5 m³/min, approximately 18–124 CFM, and 2–10 bar. It uses 3 mm pellets, holds 15 kg of dry ice and weighs approximately 82 kg without accessories. The UK-listed machine requires an electrical supply as well as compressed air. [7]
The larger hopper makes it a useful alternative to small portable units when you want fewer interruptions for filling. Compare it for regular equipment cleaning where you can move the machine around the working area.
The practical limitation is the complete setup. Confirm the nozzle, air supply and electrical version in the UK quotation. Its minimum published airflow is not a promise of maximum cleaning output from a small compressor.
Class 3 industrial machines above approximately 125 CFM
This group is relevant when cleaning coverage and sustained output justify a larger air supply. Compressor capacity, ice deliveries and moving the complete system become central purchasing decisions.
Cold Jet Aero 40FP
Our verdict: an industrial option for operators who value nozzle choice and a broad pressure range.
Cold Jet's Aero catalogue lists 50–165 CFM at 5.5 bar, depending on nozzle, with a blast pressure range of 1.4–17.2 bar and an 18.2 kg hopper. The catalogue also gives separate air ratings for individual nozzles. [8]
We would compare it for industrial maintenance and contractor work where a small portable machine would restrict coverage. Its feeding system and nozzle options deserve a demonstration using the contamination you actually need to remove.
The important qualification is pressure. The 165 CFM reference is at 5.5 bar, not at the maximum 17.2 bar. Obtain a nozzle-specific requirement for higher-pressure work and confirm the current UK configuration and supply terms. [8][11]
ASCOJET 1701
Our verdict: a relevant industrial comparison when a substantial air supply is already available.
ASCO's 2026 catalogue lists approximately 177 CFM at 7 bar with the standard nozzle. The 1701 has a single-hose system, a 23 kg pellet hopper and adjustable dry ice consumption of 25–80 kg/h. Ecoblast Supplies lists it for the UK market. [9]
We would shortlist it for recurring machinery and production cleaning where hopper capacity and straightforward operation matter. Ask to compare the standard nozzle with alternatives suited to your access and coverage requirements.
Its limitation is the demand of the standard setup. A compressor delivering 125 CFM would fall short of the quoted 177 CFM condition. Changing the nozzle changes the comparison, so have the proposed configuration sized explicitly. [9]
Kärcher IB 15/120
Our verdict: an industrial shortlist option when you can support high airflow and ice throughput.
Kärcher's UK listing specifies 2–12 m³/min, approximately 71–424 CFM, and 2–16 bar. It takes 3 mm pellets, has a 40 kg hopper and lists dry ice consumption of 30–120 kg/h. [10]
The large hopper and broad operating envelope make it relevant to substantial commercial or industrial workloads. It is a different purchasing proposition from a compact detailer's machine, especially once the compressor and pellet supply are included.
Do not size the compressor around the 71 CFM minimum if your intended nozzle and pressure need much more. The published maximum airflow and maximum pressure are separate limits; obtain the demand for your actual operating point. [10]
What compressor does a dry ice pellet blaster need
Specify free air delivery at the pressure needed by the selected nozzle and machine. Include pressure losses through hoses, couplings, filters and air treatment, plus any other equipment using the same supply.
| Machine | Published airflow reference | Rating conditions and compressor check |
|---|---|---|
| Champ Neo | Approximately 5–9 CFM; 150–250 L/min | Operating manual reference at 5 bar; confirm the current nozzle and UK specification |
| Champ Turbo | Approximately 18–57 CFM; 500–1,600 L/min | Range depends on pressure and nozzle; size for the intended combination |
| Champ Vario | Approximately 11–53 CFM; 300–1,500 L/min | Range depends on pressure and nozzle; low-flow operation does not cover every setup |
| ICS IC 022 EVO | Approximately 39 CFM; 1.1 m³/min | Nozzle-dependent figure; manufacturer lists 8–10 bar operating pressure |
| Champ Turbo Pro | Approximately 28–124 CFM; 800–3,500 L/min | Nozzle and pressure dependent; check delivered airflow at the chosen pressure |
| Cold Jet Aero2 PCS ULTRA | 12–100 CFM | Nozzle ratings at 5.5 bar; higher-pressure requirements must be confirmed |
| Kärcher IB 7/40 | Approximately 18–124 CFM; 0.5–3.5 m³/min | Published machine range; confirm the nozzle and pressure operating point |
| Cold Jet Aero 40FP | 50–165 CFM | Catalogue nozzle ratings at 5.5 bar; not a rating at maximum blast pressure |
| ASCOJET 1701 | Approximately 177 CFM; 5.0 m³/min | Standard nozzle at 7 bar in ASCO's 2026 catalogue |
| Kärcher IB 15/120 | Approximately 71–424 CFM; 2–12 m³/min | Published machine range; maximum pressure and maximum flow are not a paired rating |
Converted CFM figures are rounded using 1 cubic metre per minute = approximately 35.3 CFM. Ratings use different nozzles and pressure conditions. Cold Jet figures are at 5.5 bar; ASCOJET 1701 is the standard nozzle at 7 bar. Confirm total demand, operating reserve and continuous duty. See the article sources.
For compact mobile work, compare a suitably matched petrol or small diesel compressor with a workshop electric supply. For larger industrial setups, the compressor may become the biggest and heaviest part of the package.
An aftercooler and water separator can remove heat and condensed water; they do not automatically provide every machine's required air quality. Follow the specified requirements for moisture, oil and particles. [1][4][7]

What to compare before buying
The cleaning result: Test the same contamination on the same material, using the air supply you expect to have. Compare coverage per minute, finish and operator access. Maximum pressure alone is an incomplete measure of performance.
Pellet compatibility and deliveries: Confirm the accepted pellet diameter and whether a crusher or particle-control system is included. Plan deliveries around actual use, storage and the fact that dry ice gradually sublimates. A high-throughput machine needs a dependable supply. [1][6]
Ice use per completed job: Compare the amount of ice needed to achieve the required finish, alongside labour time. A high maximum feed rate is a capability, rather than evidence that the machine is expensive or economical to run on your work.
The complete equipment package: Check the compressor, air treatment, hose lengths, electrical supply where needed, additional nozzles, training, delivery and VAT. Compare UK support and spare-part arrangements as well as the machine price.
The working environment: Include ventilation and CO₂ monitoring where required, noise control, suitable PPE and collection of removed contamination in the job plan. Dry ice becoming gas does not remove the need to manage the workplace or the material being cleaned off. [1]
Frequently asked questions
Which dry ice pellet blaster is best for mobile car detailing
Our starting comparison is the Champ Turbo versus Champ Vario. The Turbo offers a straightforward portable setup; the Vario adds useful control over ice dosing in a lighter unit. The Neo is worth considering for lighter, occasional work. Compare an ICS IC 022 EVO if you want another compact pellet-fed option. For demanding underbody work, prove the required result before choosing the machine and compressor. [1–4]
Can I run a dry ice blaster with a 50 CFM compressor
Some configurations can operate within that supply, provided 50 CFM is the delivered output at the required pressure and continuous duty is supported. A 50 CFM compressor is below the published top of the Turbo's and Vario's airflow ranges. Expect nozzle and pressure restrictions where demand exceeds the available air. Check the complete operating point rather than buying on a minimum figure. [2][3]
Is a higher CFM dry ice blaster always better
Higher airflow can support larger nozzles and greater coverage, but it also increases the size of the air supply you need. Detailed work may benefit more from control and access. The best choice is the setup that achieves the required finish at a commercially useful speed.
Do particle control machines still use dry ice pellets
Yes. The Cold Jet PCS ULTRA loads 3 mm pellets and cuts them into smaller selectable particles before blasting. It is a pellet-fed machine despite its finer output. [6]
Will dry ice blasting remove rust and paint
It can remove some coatings and loose contamination, but results depend heavily on adhesion, thickness and the underlying surface. It should not be sold as a universal substitute for abrasive blasting where a corrosion-free surface or a defined anchor profile is required. Arrange a representative test before quoting a removal rate or finish. [12]
Can one machine handle detailed and industrial cleaning
Some machines offer broad adjustment, but the nozzle, airflow, pellet feed and access still limit the result. The Vario and PCS ULTRA are worth comparing when control matters; the Turbo Pro offers a more portable route to higher output. The Aero 40FP, ASCOJET 1701 and IB 15/120 belong on the shortlist when the workload supports a larger complete system. [3][5][6][8–10]
Final thoughts
For a compact UK setup, start by comparing the Champ Turbo and Champ Vario, with the Neo for lighter work and the ICS IC 022 EVO as an alternative.
Move to the Turbo Pro, PCS ULTRA or IB 7/40 when the work calls for greater output, more control or a larger hopper. Consider the Aero 40FP, ASCOJET 1701 and IB 15/120 when industrial cleaning justifies a substantial air supply.
