The unit houses two FVO-400RC indirect fired oil-burning heaters, each rated at 390,000 BTU\/h, delivering a combined output of 780,000 BTU\/h. Airflow of up to 4,000 CFM is distributed through either four 12-inch diameter or two 16-inch diameter duct outlets. Licensed HVAC contractors and certified heating technicians typically deploy this unit on projects requiring clean, indirect heat delivery to occupied or enclosed spaces.\u003c\/p\u003e\n\u003cp\u003eThe FVO-1100TR is suited for large residential and commercial construction projects, civil infrastructure work, industrial shutdowns, and remote operations where a permanent heat source is unavailable. The integrated onboard generator allows operation where no grid power is accessible. The 299-gallon steel fuel tank with TC-approved capacity supports extended run times without refueling, making the unit practical for continuous overnight heating shifts or multi-day remote deployments. The recirculating air inlet configuration allows the unit to draw and recondition air from within a heated space, improving thermal efficiency in enclosed structures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDual FVO-400RC indirect fired oil heaters with combined 780,000 BTU\/h output\u003c\/li\u003e\n  \u003cli\u003eWelded 304 stainless steel heat exchanger for corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003eRiello burner technology with Tiger-Loop fuel system for reliable combustion\u003c\/li\u003e\n  \u003cli\u003e299-gallon onboard steel fuel tank with 110 percent full fuel containment\u003c\/li\u003e\n  \u003cli\u003eIntegrated generator enables self-contained operation at remote sites without grid power\u003c\/li\u003e\n  \u003cli\u003eBackward incline blower delivers up to 4,000 CFM with low noise and low amperage draw\u003c\/li\u003e\n  \u003cli\u003eDual-axle trailer frame with four 15-inch galvanized rims and radial tires for site mobility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a self-contained trailer unit incorporating two FVO-400RC indirect fired heaters. Outlet ducting is compatible with FV-HD12 (12-inch) duct components. Verify duct sizing and fuel supply connections against site-specific requirements before deployment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDeployment and commissioning should be performed by qualified HVAC or heating contractors familiar with indirect fired oil-burning equipment and applicable codes. Before servicing either heater unit, shut down the burners, allow heat exchangers to cool, and de-energize the onboard generator. Fuel system connections and containment integrity should be inspected prior to each use in accordance with local fire code and the applicable installation standard. Do not operate in fully sealed, unventilated spaces; indirect fired units exhaust combustion gases externally, but adequate fresh-air makeup must still be confirmed for the heated space.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeating Capacity\u003c\/strong\u003e: 2 x 390,000 BTU\/h (780,000 BTU\/h combined)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Airflow\u003c\/strong\u003e: 4,000 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Outlet\u003c\/strong\u003e: 4 x 12-inch diameter or 2 x 16-inch diameter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Inlet\u003c\/strong\u003e: 2 x 16-inch diameter (recirculating)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuel Tank Capacity\u003c\/strong\u003e: 299 US gallons (TC approved)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuel Containment\u003c\/strong\u003e: 110 percent full fuel containment\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeat Exchanger Material\u003c\/strong\u003e: Welded 304 stainless steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBurner Technology\u003c\/strong\u003e: Riello burner with Tiger-Loop fuel system\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Supply\u003c\/strong\u003e: 115 volts (integrated generator included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: 192 x 88.8 x 84 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4300 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrailer Configuration\u003c\/strong\u003e: Dual axle, 4 x 15-inch galvanized rims with radial tires\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FLAGRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FVO-1100TR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FLAGRO","offers":[{"title":"Default Title","offer_id":51306355982642,"sku":"FVO-1100TR","price":46946.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309549405.png?v=1781290278","url":"https:\/\/voomisupply.com\/products\/flagro-fvo-1100tr-indirect-fired-trailer-heater-780000-btu-h","provider":"Voomi Supply","version":"1.0","type":"link"}
