As an indirect heater the unit keeps the combustion gases strictly apart from the warm air: the exhaust must be led outside through a flue pipe on the Ø 200 mm chimney connection, and only warm air free of combustion gases is delivered. The fan builds up a static pressure of 250 Pa, which allows long air-distribution hoses to be connected to the Ø 270 mm warm-air outlets, so the unit can stand outdoors while the heat is carried to where it is needed.\u003c\/p\u003e\u003ch4\u003eKey benefits\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndirect heating\u003c\/strong\u003e — the exhaust leaves through the flue; the warm air stays free of combustion gases.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure for hose runs\u003c\/strong\u003e — 250 Pa of static pressure for long air-distribution hoses; four air outlets, warm-air outlet Ø 270 mm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree fuels\u003c\/strong\u003e — runs on diesel, HVO 100 or kerosene; fuel preheater and cold-start button.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMonitored operation\u003c\/strong\u003e — InfoAir remote monitoring system, electronic flame monitoring with photocell, limit thermostat for the fan with automatic reset and limit thermostat with manual reset.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermostat control\u003c\/strong\u003e — digital control with fan-only function; optional analogue or digital room thermostats regulate the temperature automatically.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt for site logistics\u003c\/strong\u003e — steel housing built for outdoor use, trolley design, crane eyes and forklift pockets; protection class IP44.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTypical applications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLarge construction sites\u003c\/li\u003e\n\u003cli\u003eIndustrial halls\u003c\/li\u003e\n\u003cli\u003eEvent tents\u003c\/li\u003e\n\u003cli\u003eOutdoor placement with warm air ducted inside through hoses\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical data\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eArticle number:\u003c\/strong\u003e 4013500 · EAN: 8053670896802\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeating power:\u003c\/strong\u003e 136 kW (116,900 kcal\/h · 464,000 Btu\/h)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir volume:\u003c\/strong\u003e 8,500 m³\/h · 4 air outlets · air pressure max. 250 Pa\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeating type:\u003c\/strong\u003e indirect · chimney connection Ø 200 mm · warm-air outlet Ø 270 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel:\u003c\/strong\u003e diesel, HVO 100 or kerosene · oil consumption max. 12.93 l\/h (approx. 10.8 kg\/h)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMains connection:\u003c\/strong\u003e 220–240 V, 50 Hz · power input 1.5 kW · rated current 6.9 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection class:\u003c\/strong\u003e IP44 · steel housing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment:\u003c\/strong\u003e InfoAir remote monitoring system · analogue or digital thermostat control · cold-start button · digital control · electronic flame monitoring with photocell · fan-only function · fuel preheater · limit thermostat for the fan with automatic reset · limit thermostat with manual reset · separate Riello oil burner · stainless-steel combustion chamber · two oil filters (oil pump and suction filter)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e trolley design · crane eyes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (L × W × H):\u003c\/strong\u003e 1,790 × 880 × 1,360 mm · Weight: 270 kg\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOriginal Master equipment (Dantherm Group)\u003c\/strong\u003e — supplied with full manufacturer documentation by BMB Rheinland, your authorised distribution partner.\u003c\/p\u003e\u003cp\u003ePlanning a project or a larger requirement? \u003ca href=\"\/pages\/contact\"\u003eRequest a quote\u003c\/a\u003e.\u003c\/p\u003e\u003chr\u003e\u003ch3\u003eDownloads\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/danthermpublicfiles.blob.core.windows.net\/en-master-manuals\/Master-BV-311-471-691-user-manual-4241324-INFOAIR-Multi.pdf\" target=\"_blank\"\u003e📄 Operating manual Master BV 471 \/ BV 691 InfoAir (multilingual, incl.
