With an effective heating volume of 1,131 m\u00b3 (and a communicated capacity of 1,600 m\u00b3 with good insulation), this model offers an excellent balance between power, consumption and ease of use. The radiator runs on red diesel or biodiesel and consumes only 1.5 litres per hour. This makes it particularly economical in daily use.<\/p>\n<p data-start=\"1184\" data-end=\"1673\">Thanks to the infrared technology, there is no air movement and dust accumulation is eliminated, making the WHO-135 ideal for sensitive environments. Combustion is completely enclosed and odourless, preserving air quality in the room. The heater has a low noise level of only 32 dB, ensuring a quiet working environment without distractions. The built-in thermostat with a range of 0 to 40 \u00b0C offers precise temperature control, tailored to the desired situation.<\/p>\n<p data-start=\"1675\" data-end=\"2099\">The WHO-135 is equipped with durable transport wheels (75 mm), making it easy to move the unit within or between work zones. Despite its power output, power consumption is limited to 50W, making this infrared heater also suitable for long-term use on temporary sites or in combination with generators. The robust design guarantees reliability and a long service life, even in intensive use.<\/p>\n<p data-start=\"2101\" data-end=\"2378\">For professionals looking for quiet, focused heat without compromising on durability or comfort, the WHO-135 is an excellent choice.
