Therma-Steem Industrial 400: Continuous-Fill Dry Vapor Steam at 180 PSI and 380°F
The Therma-Kleen THE-IN4 is the highest-pressure electric steam cleaner in the Therma-Steem line, generating 97% dry vapor steam at 180 PSI (10.6 bar) and up to 380°F (193°C). Its 2-gallon stainless steel reserve tank feeds the 1.5-gallon boiler while the machine runs — eliminating the pressurize-cool-refill cycle that interrupts work on fixed-tank units. Plug into any 110V outlet and the Industrial 400 is ready to clean in minutes, no plumbing or special installation required. Made in the USA.
Industrial-Grade Boiler, Continuous Fill, and Comprehensive Safety Systems
1.5-gallon stainless steel boiler with separate 2-gallon stainless steel reserve tank for continuous operation
180 PSI / 10.6 bar output pressure — 80% higher than the TS10 — blasts through carbonized grease and industrial residue
380°F / 193°C steam temperature exceeds thermal disinfection thresholds required in food processing and healthcare
97% dry vapor output keeps moisture-sensitive surfaces safe; no chemical additives required
Low water alarm, high-pressure relief valve, pressure limit switch, and temperature high cut-off
Heavy-duty stainless steel body; 15-foot stainless steel steam hose with gun included
Industries Where the Industrial 400 Delivers Results
The THE-IN4's combination of high pressure and high temperature makes it the standard choice for applications that would overwhelm a lighter-duty steam cleaner. Food processing facilities use it to sanitize conveyor belts, vats, slicers, and stainless steel prep surfaces — surfaces that must meet HACCP and NSF compliance standards that prohibit chemical residues. In healthcare, the 380°F output surpasses the kill temperature for C. diff spores and other hospital-acquired pathogens on hard surfaces. Hospitality operators clean commercial kitchen exhaust hoods, tile grout, and laundry areas between chemical treatments. Auto detailers and fleet maintenance shops use the 180 PSI pressure to break loose road grime from wheel wells, undercarriages, and engine bays. The continuous-fill reserve tank means operators can work through an entire shift on a single machine without downtime.
Continuous Fill vs. Fixed Tank, Steam Compliance, and Included Accessories
The defining advantage of the Industrial 400 over models like the TS10 is continuous fill: water from the 2-gallon reserve tank is fed into the pressurized boiler through an automatic fill system, so the machine never needs to be shut down, cooled, and refilled mid-job. At 110V / 18A (~1,980W), the unit draws roughly 30% more power than the TS10 to maintain higher pressure and temperature simultaneously. The 97% dry vapor output complies with HACCP protocols for chemical-free sanitization in food-contact environments and supports NSF-compliant cleaning procedures in commercial kitchens. The complete package includes a 15-foot stainless steel hose with gun, 20″ and 36″ wand extensions, nylon/brass/stainless steel brushes in multiple sizes, specialized brushes for curved surfaces and zero-degree blasting, terry cloth towels, microfiber cloths, handheld squeegee, gloves, safety glasses, funnel, and hardware for assembly.

What makes the Industrial 400 different from the Therma-Steem #10?
The THE-IN4 operates at 180 PSI and 380°F versus the TS10's 100 PSI and 330°F. More importantly, the Industrial 400 includes a 2-gallon stainless steel reserve tank that feeds the boiler while the machine runs, enabling continuous operation without shutdown for refilling.
Does the Therma-Steem Industrial 400 require a special electrical outlet?
The Industrial 400 runs on 110 VAC at 18 amps (approximately 1,980W). A dedicated 20-amp circuit is recommended. A 220 VAC / 9-amp option is also available for facilities with that service.
Is the Industrial 400 compliant for use in food processing environments?
Yes. The 380°F dry vapor steam exceeds thermal kill thresholds required under HACCP protocols, and the chemical-free output supports NSF-compliant sanitization on food-contact surfaces such as conveyor belts, vats, and stainless prep surfaces.
How does the continuous-fill system work on the THE-IN4?
The 2-gallon stainless steel reserve tank automatically feeds water into the 1.5-gallon pressurized boiler while the machine is operating. This eliminates the need to shut down, depressurize, cool, and manually refill — allowing uninterrupted cleaning during full commercial shifts.
What accessories are included with the Industrial 400?
The package includes a 15-foot stainless steel hose with gun, 20″ and 36″ wand extensions, nylon/brass/stainless steel brushes in multiple sizes, specialized curved-surface and zero-degree blasting brushes, terry cloth towels, microfiber cloths, handheld squeegee, gloves, safety glasses, funnel, and assembly hardware.
What industries use the Therma-Steem Industrial 400?
Primary users include food processing plants (conveyor belts, vats, slicers), healthcare facilities (hard-surface disinfection of patient rooms and OR suites), commercial kitchens and restaurants (hood cleaning, tile grout), hospitality (deep cleaning between chemical treatments), and auto detailing and fleet maintenance shops.

I just wanted to let you know that I will be submitting a PO in the next few weeks for a second TS400 Dry Steam Cleaner from you guys. This first unit we purchased from you has been an absolute game changer! We currently use this to clean our dry calibration blocks (Dry Sizers) We run PVC fence and our compound has a high amount of wax which results plate-out and builds up in the calibration. What happens is once the calibrators plug up, we take the line down, disassemble everything clean and put back together then start the line back up.
Prior to purchasing one of these units from you, a typical cleaning would take two to three hours depending on the size of tool we were cleaning. This was done all by hand and very labor intensive. Our cleanings have been cut down to twenty or thirty minutes tops. What use to take three employees now only takes one. This unit payed for itself the very first tool we cleaned. Looking forward to purchasing this second unit from you. Talk soon!
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!!
