Black and strong

Storage facilities and production halls, agricultural businesses and construction sites pose special demands to a heating system. Due to the continuous supply of cold air, for example through open doors as well as missing windows in a building envelope, it is not possible to provide for a well-tempered working climate with a conventional heating.

Heating economically with the directly fired oil heater fan IDX 31 D

Designed for the robust industry application, in the building trade and the agricultural sector, the thermostat-controlled direct oil heater fan IDX 31 D is an especially economic solution – even in continuous operation. With a maximum consumption of only 3 litres of oil per hour, the 30 kW power pack generates a volume of up to 750 m³/h of hot air. No other heating solution supplies direct warmth more efficiently and budget-friendly into open or constantly ventilated rooms.

Mobile and robust

Owing to its practical carriage construction with an integrated 38 litre fuel tank, the strikingly black direct oil heater is prepared for a quick change of location at any time. To allow for easy temperature control, the oil heater fan IDX 31 D comes equipped with a steplessly variable thermostat with a digital actual value indication. A second digital display supplies information about the respective current room temperature. The easy-to-read filling level indication reliably informs you about the remaining fuel quantity. Thanks to the electronic flame trap and the integrated overheating protection, maximum operational reliability is ensured at all times.

Working in the warmth – and preventing work stoppage

Whether you're working in the workshop, in the stable, in well-ventilated storage facilities or in roofed outdoor areas – in all the places where no heating is available or where an effective additional heating is required, the oil heater fan IDX 31 D convinces. For example, to prevent you from having to interrupt or even stop work on the construction site in cold temperatures, we recommend heating the shell construction rooms. Building materials such as screed or plaster require a specific minimum temperature to remain well processible. Use the directly fired oil heater fan IDX 30 D to provide for adequate temperatures in well-ventilated rooms to complete your work on schedule.

Thermostat-controlled temperature setting

The uncomplicated temperature selection (in the range from 5 - 45 °C) is carried out via a steplessly adjustable thermostat with an additional setpoint and actual value dual display. When the desired temperature is reached, the IDX 31 D is switched off fully automatically and is also switched on again automatically when this temperature is undercut.

Quick start-up,low-maintenance operation, easy handling

Concentrate on your work and leave everything else to the direct oil heater fan IDX 31 D. Unattended heating operation can be implemented without any problems. The compact heating device is delivered in a partly pre-assembled state – in the final assembly process you just have to mount the wheels, the frame and the handle.

With the direct oil heater fan IDX 31 D you rely on an effective and economic heating concept – to ensure that chilliness no longer stands a chance.
