Therma-Kleen Ultra 600 Propane Steam Cleaner – 600 PSI, 350°F, 1.5 GPM

The Therma-Kleen Ultra 600 is the highest-pressure propane-fired commercial steam cleaner USCT carries — 600 PSI at 350°F at 1.5 GPM, propane-heated for outdoor and high-output commercial work where electric units stall. Specified for restaurant grease line cleaning, food-truck deep-cleans, fleet washing, and concrete prep. Made in the USA. Stainless steel boiler with a 10-year warranty. 1.5 GPM continuous output suits multi-bay and on-the-road operations.

Ultra 600 Propane Steam Cleaner — 600 PSI Industrial Degreasing Without Chemicals

The Ultra 600 produces 2.4× more pressure than the Ultra 250 — 600 PSI at 350°F versus 250 PSI — in the same 23" × 18" × 32" chassis at 100 lbs. The higher pressure unlocks industrial degreasing applications where the Ultra 250's 250 PSI is insufficient: packed grease on conveyor chains, road film on fleet vehicles, and equipment crevices where lower pressure steam cannot penetrate. Same 130,000 BTU/hr propane burner, same 1.5 GPM adjustable flow, same EPA clean-burn standard — just higher pressure output.

Ultra 600 Steam Temperature, PSI, and Propane Output

When the Ultra 250 isn't enough pressure and the XL electric series isn't practical without 3-phase power, the Ultra 600 fills the gap with propane-powered 600 PSI output usable anywhere with a propane supply and standard outlet.

• 600 PSI output pressure (41 bar) — industrial-grade penetration into packed grease, scale, and road film; adjustable down for delicate surfaces
• 350°F maximum steam temperature — 138°F above the thermal sanitization threshold; effectively kills most pathogens without chemical addition
• 1.5 GPM water volume — same flow as Ultra 250; pressure is the differentiator, not water consumption
• 130,000 BTU/hr propane burner — rapid heat-up; EPA clean-burning rated for outdoor and semi-enclosed use
• Electronic pilot ignition — reliable start in outdoor conditions; combined with flow switch, pressure relief valve, and high temperature limit switch
• 25 ft high-pressure steam hose included — 100 ft hose available as optional accessory

Ultra 600 Applications and Environments

Fleet washing and vehicle maintenance facilities use the Ultra 600 for road film and undercarriage degreasing where high pressure and heat together outperform chemical degreasers alone. Food processing equipment — fryers, ovens, conveyor systems — benefits from the combination of 600 PSI penetration and chemical-free sanitation that satisfies USDA compliance. Agricultural equipment cleaning between seasons uses the propane power source where electrical service is unavailable in the field. The Ultra 600 targets applications where the Ultra 250 at 250 PSI reaches the cleaning threshold but cannot push through heavy contamination — the same footprint and propane requirement, 2.4× more pressure.

Ultra 600 Steam Temperature, PSI, and Dry-Steam Output

Output temperature: 350°F (176°C). Output pressure: 600 PSI (41 bar). Water volume: 1.5 GPM. Burner output: 130,000 BTU/hr. Ships with: 4 ft wand with trigger gun, blast nozzle, fuel pressure gauge, LP gas quick connect, main propane regulator, 25 ft high-pressure steam hose, instructional manual and DVD. Fan nozzle for the Ultra 600 is sold separately (different specification from the Ultra 250 fan nozzle — verify when ordering). For environments needing 97% dry vapor steam with continuous-fill capability, the XL1 or XL3 electric series may be more appropriate for fixed installations.
