Therma-Kleen THE-IN4 Industrial Steam Cleaner – 180 PSI, 380°F, Continuous Fill

The Therma-Kleen THE-IN4 (Therma-Steem Industrial 400) is the highest-pressure electric dry vapor steam cleaner in its class — 180 PSI at 380°F with 97% dry vapor output. Continuous fill from a 2-gallon stainless reserve tank feeds the 1.5-gallon boiler for uninterrupted commercial use. Specified for food processing, automotive shops, and heavy-grease industrial sanitation where sub-200 PSI machines stall.

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.
