Ceramic fan heater TDS 20 C

Hot look, convincing features – remarkably well combined

Whether in a workshop, construction trailer or hall, or during assembly work – when performing mobile heating tasks, the ceramic fan heater TDS 20 C with its both robust and lightweight metal housing painted in signal red can impress with remarkable features.

And since our distinctive logo has been imprinted on the outside of the device, we have also incorporated distinct extras inside, which make all the difference to conventional standard electric heater fans with heating wire technology.
For unlike conventional electric heating devices, the TDS 20 C uses an advanced PTC ceramic heating element for heating the air. Advantages of PTC as compared to heating wires: longer lifetime, less sensitive technology, shorter heat-up times, process-related overheating protection – and no burning of dust during heating, which additionally makes this ceramic heater suitable for allergy sufferers.

Thanks to the smoothly running fan and the large heater battery surface, you can benefit from a pleasantly homogeneous, draught-free hot air current – which is, moreover, usually produced in a more silent way. As an additional plus in safety, the integrated ceramic heating element also increases the fan heater’s stability.
With its two heating levels that can be set separately, the TDS 20 C can be variably switched to 2 kW or 3 kW heating operation and, in combination with its powerful axial fan, provides pleasant warmth in cold rooms.

The desired temperature can be regulated as needed via the integrated infinitely variable thermostat of the TDS 20 C. If required, the fan can also be used in sole fan operation without heating function.

Faster air heating – more uniform room temperature

Trotec’s fan heaters with PTC ceramic heating elements (A) not only differ from conventional heating coil technology (B) in terms of their shorter heat-up times. There are also process-related differences in the response behaviour of the heating elements.

Although both devices maintain the preselected target temperature (orange) by means of thermostat control using a two-position controller, the respective temperature adaptation takes place significantly more slowly and with greater deviations from the desired target temperature in case of devices with heating coils. The reason for this is the different conductivity behaviour of the heating elements:

if current flows through the heating coils, the coils will always have the same temperature once they have heated up. For controlling the desired room temperature, the power supply is first interrupted, making the coil cool down, and then re-activated by the thermostat so that the coil heats up again completely before it is switched off again when the set target temperature is reached.

This “on/off process” causes significantly greater temperature fluctuations than with ceramic heating elements, for the material of the latter provides an integrated temperature self-regulation. The hotter PTCs get, the higher is their electrical resistivity, resulting in less current flowing through the heating element and in a reduced heating capacity, and thus in significantly lower temperature fluctuations and less switch-on and switch-off processes in thermostat-controlled operation.

For this reason, ceramic fan heaters are able to create more even room temperatures for temperature-sensitive manufacturing processes as well as a pleasant working climate.

Two heating levels provide a heat output of either 2 or 3 kW in thermostat-controlled automatic operation, while the cold air level additionally allows for ventilation without heating.
Multi-stage temperature control with two heating levels

Reliable heating solutions with an optimum value-for-money ratio – suited for manifold fields of application:

  • Construction trailers
  • Greenhouses
  • Boathouses
  • Garages
  • Market stalls
  • Workshops and halls
  • Catering trade

Special features:

  • Fastening preparation for wall and ceiling mounting
  • Controllers recessed for protection

Practical tip:

Instead of positioning them on the floor, you can also flexibly mount the ceramic fan heaters of the TDS-C series to a wall or ceiling. For as they leave the factory, these electric heaters are already fitted with two fastening threads mounted to the sides that serve to accommodate the optionally available wall and ceiling holders.

This way you can use the heating devices without creating a trip hazard or obstructing a passage, for instance when heating construction trailers, market stalls, greenhouses, small halls, garages, workshops or boathouses.

The flexibly usable wall and ceiling holders are optionally available for all TDS-C models.
