WELTEM WHO-250F diesel infraroodstraler 29 kW \u2013 maximaal vermogen met ingebouwde ventilator voor grote industri\u00eble ruimtes<\/h2>\n

De WELTEM WHO-250F diesel infraroodstraler<\/strong> biedt effici\u00ebnte, stille warmte voor ruimten tot 4.680 m\u00b3, verwarmt effectief ongeveer 2.100 m\u00b3 op slechts 2,35 l\/u brandstof. In tegenstelling tot traditionele heteluchtblazers verwarmt de infraroodtechnologie de vloeren, muren, machines en mensen in de ruimte rechtstreeks met een ingebouwde ventilator voor een snellere warmteverdeling, zodat de warmte bijna onmiddellijk wordt gevoeld en gelijkmatig verspreidt zonder luidruchtige, stoffige tocht.<\/p>\n

Met een geluidsniveau van slechts 32 dB, een instelbare thermostaat (0\u201340 \u00b0C) en een afstandsbediening combineert de WHO-250F comfort met controle. Het lage, eerlijke brandstofverbruik en de schone, geurloze verbranding maken het een economische en milieubewuste keuze voor gebruik binnenshuis, ondersteund door 3 jaar fabrieksgarantie.<\/p>\n

Waarom kiezen voor de WELTEM WHO-250F?<\/h2>\n

WELTEM-kachels zijn gebouwd met extra metaal, grotere branderbuizen en hoogwaardige reflectorpanelen, wat zorgt voor een robuuste constructie, een hoger warmtevermogen en een langere levensduur dan vergelijkbare modellen. De WHO-250F is bovendien voorzien van een ingebouwde ventilator voor een snellere en wijdere warmteverdeling, wat zorgt voor extra flexibiliteit bij het verwarmen van uw ruimte. Omdat het vermelde brandstofverbruik precies is wat u krijgt, blijven uw operationele kosten seizoenen lang voorspelbaar.<\/p>\n

Waar de WHO-250F te gebruiken<\/h2>\n

De WHO-250F is ideaal voor grote industri\u00eble hallen, magazijnen, evenementententen en overdekte buitenruimtes. Dankzij de grote wielen, het mobiele ontwerp en de rookgasloze werking is hij snel in te zetten waar betrouwbare, comfortabele warmte nodig is.<\/p>\n
