The Ultra 250 is Therma-Kleen's entry-level propane steam cleaner — compact at 95 lbs with a 23" × 18" × 32" footprint, but producing 250 PSI at 350°F from a 130,000 BTU/hr propane burner. Unlike the electric XL series which requires 3-phase power, the Ultra 250 runs on propane with a 115VAC / 6.8A or 220VAC / 3.5A pilot ignition circuit — operable in any facility or outdoor location with propane access and a standard outlet. Water flow is adjustable from 0.5 to 1.5 GPM for precision control between delicate surface cleaning and aggressive degreasing.
Ultra 250 Steam Temperature, PSI, and Propane Output
The propane burner is the key differentiator from the electric XL series — no 3-phase power infrastructure required, but also no continuous-fill capability (the propane tank determines operational duration).
250 PSI output pressure (17 bar) — less than the Ultra 600 but sufficient for grease removal, tile cleaning, conveyor degreasing, and exterior surface sanitation
350°F maximum steam temperature — 138°F above the thermal sanitization threshold; kills most pathogens without chemical sanitizers
1.5 GPM adjustable flow (0.5–1.5 GPM) — reduce to 0.5 GPM for delicate surfaces; increase to 1.5 GPM for faster throughput on heavy contamination
130,000 BTU/hr propane burner — rapid heating; EPA clean-burning rating for outdoor and semi-enclosed use
Electronic pilot ignition — reliable start without manual lighting; combined with flow switch, pressure relief valve, and high temperature limit switch for safe operation
25 ft high-pressure steam hose included — standard reach; 100 ft hose available as optional accessory for large equipment or long-distance cleaning
Ultra 250 Applications and Environments
Outdoor facilities and locations without 3-phase electrical service are the primary Ultra 250 application — construction sites, agricultural equipment cleaning, food truck sanitation, and outdoor event equipment are all viable without permanent electrical infrastructure. Chemical-sensitive facilities like KOSHER kitchens, organic food processing areas, and pharmaceutical manufacturing spaces use it where chemical sanitizer residue creates compliance issues. The EPA clean-burn rating makes it usable in semi-enclosed areas like loading docks and covered outdoor equipment bays. For indoor applications in fully enclosed spaces, confirm adequate ventilation — propane combustion generates CO2 and requires airflow.
Ultra 250 Steam Temperature, PSI, and Dry-Steam Output
Output temperature: 350°F (176°C). Output pressure: 250 PSI (17 bar). Water volume: 1.5 GPM maximum, adjustable down to 0.5 GPM. Burner output: 130,000 BTU/hr. Ships with: 4 ft wand with trigger gun, blast nozzle, fan nozzle (Ultra 250 specific), 25 ft high-pressure steam hose, LP gas quick connect, main propane regulator, fuel pressure gauge, instructional manual and DVD. For locations that need 600 PSI rather than 250 PSI, the Ultra 600 provides 2.4× more pressure at the same 350°F temperature and 1.5 GPM flow rate in the same chassis size.

The Ultra 250 produces 250 PSI (17 bar) at the output nozzle. For comparison, the Ultra 600 produces 600 PSI in the same chassis at the same temperature and flow rate. If your application requires penetration into grease-packed equipment or industrial-grade degreasing, the Ultra 600 provides 2.4× more pressure.
Does the Ultra 250 require 3-phase electrical service?
No. The Ultra 250 runs on propane with a 115VAC, 6.8-amp pilot ignition circuit (or 220VAC, 3.5A). Standard single-phase outlets are sufficient. Only the electric XL series (XL1, XL3) requires 3-phase service.
What is the water flow rate and can it be adjusted?
Water flow is adjustable from 0.5 GPM to 1.5 GPM via a pump valve. Use 0.5 GPM for delicate surfaces or precision cleaning; increase to 1.5 GPM for faster throughput on heavily contaminated equipment.
Can the Ultra 250 be used indoors?
The Ultra 250 requires adequate ventilation — propane combustion generates CO2 and requires airflow. It is rated for outdoor use and semi-enclosed areas with ventilation (loading docks, covered bays). For fully enclosed indoor environments without ventilation, the electric XL series is the appropriate choice.
Is a longer hose available for the Ultra 250?
Yes. The standard configuration includes a 25 ft high-pressure steam hose. A 100 ft steam hose is available as an optional accessory for large equipment, long-distance cleaning, or situations where moving the machine is impractical.
What safety features are built into the Ultra 250?
The Ultra 250 includes: electronic pilot ignition (no manual lighting), high temperature limit switch (shuts down if temperature exceeds safe threshold), pressure relief valve (releases if pressure exceeds rated limit), and flow switch (prevents heating without water flow to protect the coil).

Perfect vacuum cleaner
Perfect vacuum cleaner. Well made , goes around chair & table legs easily
Located in the Twin Cities in Minnesota, we acquired our Brio Air Filter in mid-late Spring of this year (2023) when pollen count was high and we were beginning to experience the effects of Poor Air Quality Index as a result of smoke particulates from fires in Canada that caused the air in much of Minnesota to become hazy and simply dirty.
It is so easy to share our experience with the Brio Air Filter given how quickly and efficiently it removed pollen, dust, and smoke particles from the environment inside our home. Two people in our home who suffer from pollen-related allergies during the spring immediately experienced easier breathing and elimination of symptoms within the house. With respect to smoke particulates from Canada drifting into our environment, EVERYONE in our home experienced directly improved breathing and smell of the air when entering from outside.
An additional piece of information to account for is that we have always employed high grade furnace filters in our home’s central HVAC system. With that high grade filtration in place both prior to and after acquiring a Brio home air filter, we all quickly agreed that deploying the Brio in our home made an easily noticeable positive difference in breathing inside our home. Additionally, those of us who clean our home have observed that dust builds up slower on our floors and furniture than before we deployed the Brio unit.
We did note that the Brio is not as quiet as a few other brands/models on the market that we have tried in our home but the efficiency and quality of the filtration, along with the air turnover rate it provides,allows us to locate the Brio unit in central rooms away from the bedrooms. Since we made that change there has been no noise-related effect on our sleep, while the unit maintains the same level of air cleanliness throughout our home.
A last key point to make is how easy the Brio unit is to maintain. The simplicity of the modular construction of the Brio unit makes it very quick and easy to keep the filtration sections clean. We have not yet reached a point of filter replacement but it is obvious to us that the replacement will take a matter of seconds and can be executed by anyone in our home, including our 10-year-old son.
It seems to help reduce my allergy issues. We're glad we bought it. The only problem I had was not seeing any cubic footage recommendations in the online description when purchasing the unit. Bedrooms vary widely in size!!
