WELTEM WHO-250F Diesel infrarotstrahler 29 kW \u2013 maximale Leistung mit integriertem Ventilator f\u00fcr gro\u00dfe Industriehallen<\/h2>\n

Der WELTEM WHO-250F Diesel infrarotstrahler<\/strong> bietet effiziente, leise W\u00e4rme f\u00fcr R\u00e4ume bis zu 4.680 m\u00b3, heizt effektiv rund 2.100 m\u00b3 bei einem Kraftstoffverbrauch von nur 2,35 l\/h. Im Gegensatz zu herk\u00f6mmlichen Warmluftgebl\u00e4sen erw\u00e4rmt die Infrarot-Technologie B\u00f6den, W\u00e4nde, Maschinen und Personen im Raum direkt mit einem eingebauten Ventilator f\u00fcr eine schnellere W\u00e4rmeverteilung, sodass die W\u00e4rme fast sofort sp\u00fcrbar ist und sich gleichm\u00e4\u00dfig ohne laute, staubige Zugluft ausbreitet.<\/p>\n

Mit einem Ger\u00e4uschpegel von nur 32 dB, einem einstellbaren Thermostat (0\u201340 \u00b0C) und einer Fernbedienung verbindet der WHO-250F Komfort mit Kontrolle. Sein geringer, ehrlicher Brennstoffverbrauch und die saubere, geruchlose Verbrennung machen ihn zu einer sparsamen und umweltbewussten Wahl f\u00fcr den Innenbereich, unterst\u00fctzt durch eine 3-j\u00e4hrige Herstellergarantie.<\/p>\n

Warum den WELTEM WHO-250F w\u00e4hlen?<\/h2>\n

WELTEM-Heizger\u00e4te sind mit extra viel Metall, gr\u00f6\u00dferen Brennerrohren und hochwertigen Reflektoren ausgestattet, was eine robuste Konstruktion, eine h\u00f6here W\u00e4rmeleistung und eine l\u00e4ngere Lebensdauer als bei vergleichbaren Modellen erm\u00f6glicht. Der WHO-250F verf\u00fcgt zudem \u00fcber einen eingebauten Ventilator f\u00fcr eine schnellere und breitere W\u00e4rmeverteilung, was die Flexibilit\u00e4t bei der Beheizung Ihres Raumes erh\u00f6ht. Da der angegebene Kraftstoffverbrauch genau dem entspricht, was Sie erhalten, bleiben Ihre Betriebskosten Saison f\u00fcr Saison vorhersehbar.<\/p>\n

Anwendung des WHO-250F<\/h2>\n

Der WHO-250F ist ideal f\u00fcr gro\u00dfe Industriehallen, Lagerhallen, Veranstaltungselfte und \u00fcberdachte Au\u00dfenbereiche. Seine gro\u00dfen R\u00e4der, sein mobiles Design und der kaminfreie Betrieb erm\u00f6glichen einen schnellen Einsatz \u00fcberall dort, wo zuverl\u00e4ssige, angenehme W\u00e4rme ben\u00f6tigt wird.<\/p>\n
