High-performance infrared radiator for industry - WELTEM WHO-250F

The heaviest model in the professional WHO series, the WELTEM WHO-250F is designed for industrial applications where maximum heat output, efficiency and reliability are required. This diesel infrared heater is capable of heating an effective volume of 2,100 m³ with a low fuel consumption of 2.35 litres per hour, which is exceptionally economical considering its heating power of as much as 29 kW. In well-insulated rooms, the unit can even be used up to a communicated volume of 4,680 m³.

This model is equipped with an integrated fan that ensures faster and even heat distribution. Despite its power, the appliance operates with odourless, closed combustion that requires no smoke exhaust and does not affect room air quality. This makes it ideal for indoor use in sheds, hangars, production environments or large workshops. Combustion proceeds completely sealed off from the room, creating no odour, smoke or air movement.

The WHO-250F features an accurately adjustable thermostat (0-40 °C), energy-efficient electronics (only 50W power consumption) and industrial transport wheels for mobile deployment. Despite its size, it is surprisingly quiet, with a noise level of only 36 dB. In addition, this model is suitable for use with both red diesel and biodiesel, making it particularly flexible in terms of fuel choice. Built for long-term, intensive use, it minimises downtime due to its robust construction and low maintenance requirements.

With the WHO-250F, KEM Europe offers a professional heating solution for the toughest applications, where comfort, safety and durability go hand in hand. This heater is ideally suited for professionals who demand reliable performance at low cost per running hour.
