WELTEM WHO-175 Diesel infrarotstrahler 24,4 kW \u2013 leistungsstarke Strahlungsw\u00e4rme f\u00fcr gro\u00dfe Schuppen und Hallen<\/h2>\n

Der WELTEM WHO-175 Diesel infrarotstrahler<\/strong> liefert effiziente, leise W\u00e4rme f\u00fcr R\u00e4ume bis zu 3.660 m\u00b3, beheizt effektiv rund 1.600 m\u00b3 bei nur 2,2 l\/h Kraftstoffverbrauch. Im Gegensatz zu herk\u00f6mmlichen Hei\u00dfl\u00fcftern erw\u00e4rmt die Infrarot-Technologie B\u00f6den, W\u00e4nde, Maschinen und Personen im Raum direkt, sodass die W\u00e4rme fast sofort sp\u00fcrbar ist und sich gleichm\u00e4\u00dfig ohne laute, staubige Zugluft verteilt.<\/p>\n

Mit einem Ger\u00e4uschpegel von nur 32 dB, einem einstellbaren Thermostat (0\u201340 \u00b0C) und einer Fernbedienung verbindet der WHO-175 Komfort mit Kontrolle. Sein geringer, ehrlicher Kraftstoffverbrauch und die saubere, geruchlose Verbrennung machen ihn zu einer wirtschaftlichen und umweltbewussten Wahl f\u00fcr den Innenbereich, unterst\u00fctzt durch eine 3-j\u00e4hrige Herstellergarantie.<\/p>\n

Warum den WELTEM WHO-175 w\u00e4hlen?<\/h2>\n

WELTEM-Heizger\u00e4te werden mit extra Metall, gr\u00f6\u00dferen Brennerrohren und hochwertigen Reflektoren gebaut, was eine robuste Konstruktion, eine h\u00f6here W\u00e4rmeleistung und eine l\u00e4ngere Lebensdauer als bei vergleichbaren Modellen ergibt. Das Modell WHO-175 verf\u00fcgt zudem \u00fcber eine abnehmbare R\u00fcckwand f\u00fcr zweiseitige Beheizung, was zus\u00e4tzliche Flexibilit\u00e4t bei der Beheizung Ihres Raumes bietet. Da der angegebene Kraftstoffverbrauch genau dem tats\u00e4chlichen entspricht, bleiben Ihre Betriebskosten Saison f\u00fcr Saison vorhersehbar.<\/p>\n

Wo der WHO-175 anzuwenden ist<\/h2>\n

Der WHO-175 ist ideal f\u00fcr gro\u00dfe Schuppen, Lagerhallen, Werkst\u00e4tten und Industrier\u00e4ume. Seine gro\u00dfen R\u00e4der, das mobile Design und der abgasfreie Betrieb machen ihn dort schnell einsatzbereit, wo zuverl\u00e4ssige, angenehme W\u00e4rme ben\u00f6tigt wird.<\/p>\n
