Therma-Kleen Ultra 1300 Propane: 1300 PSI and 200,000 BTU/hr for Large-Scale Chemical-Free Cleaning

The TKULTRA1300 is Therma-Kleen's largest and most powerful propane-fired steam cleaner, combining a 200,000 BTU/hr LP gas burner with 1300 PSI (85 bar) output pressure and a maximum steam temperature of 350°F (176°C). Unlike electric steam cleaners that are limited by circuit capacity, the Ultra 1300 draws its thermal energy from propane — making it practical for outdoor jobsites, facilities without sufficient electrical service, and any large-scale application where runtime is unlimited by boiler tank size. Only a standard 115VAC outlet is needed for the electronic controls and ignition.

200,000 BTU Propane Burner, High-Pressure Output, and Built-In Safety Controls

• 200,000 BTU/hr LP gas burner delivers sustained high-temperature steam output regardless of ambient conditions
• 1300 PSI / 85 bar output pressure — more than 13× the pressure of the Therma-Steem #10 — for removing embedded grime, chewing gum, and industrial residue from hard surfaces
• 350°F / 176°C maximum steam temperature with 2.2 GPM low-water-volume output
• Electronic pilot ignition for reliable, consistent starts in field conditions
• High-temperature limit switch, pressure relief valve, and flow switch for safe operation
• Powder-coated painted blue steel body with aluminum coils; 195 lbs on a wheeled frame
• 50-foot high-pressure steam hose and 4-foot wand with trigger gun included

Outdoor Jobsites, Large Facilities, and Applications That Exceed Electric Capacity

The Ultra 1300 is the right tool when an electric steam cleaner simply cannot deliver sufficient pressure or runtime. Municipal maintenance crews use it for gum and graffiti removal from sidewalks, transit stations, and public plazas — the 1300 PSI cuts through vulcanized gum in seconds without solvents. Industrial facilities use it to clean large machinery, loading docks, parking structures, and outdoor equipment pads where electrical access is limited. Food processing plants clean exterior receiving areas and waste handling equipment between shifts. Because the propane tank (standard 20 lb or larger LP cylinder, not included) determines runtime rather than a boiler tank, operators can work continuously on the largest sites. The combination of high pressure and 350°F steam temperature makes chemical additives optional rather than required — effective for facilities pursuing green certification or zero-discharge compliance.

Propane Operation, Steam Output, and What Ships in the Box

The TKULTRA1300 connects to standard LP gas cylinders via a quick-connect fitting and main propane regulator included with the unit. The 200,000 BTU/hr burner heats aluminum coils to produce continuous high-pressure steam; water is supplied via garden hose connection at 2.2 GPM flow rate. For reference, 200,000 BTU/hr propane consumption is approximately 2 lbs of LP gas per hour at full output — a 20 lb tank provides roughly 10 hours of continuous operation. Only 115VAC / 13 amps is required for the control panel and electronic ignition, so the machine can operate wherever a generator or standard outlet is available. The complete package includes one blast nozzle, one fuel pressure gauge, one LP gas quick connect, one main propane regulator, one 4-foot wand with trigger gun, and a 50-foot high-pressure steam hose. Optional accessories include a 100-foot steam hose, fan nozzle, heat deflector, additional wands, inline water softener, and a full LP regulator setup with quick connects.
