Electric heater TDE 25

Electric heater TDE 25 for professional demands

For more than 25 years, professional users have appreciated the extremely robust electric heating device TDE 25 as a long-term proven heating solution for clean warmth on construction sites, in workshops and construction trailers or sales, storage and exhibition rooms.

Now this model of success has been redesigned to conquer the future, its new striking feature being the distinctive logo on the side plates of this electric heater, identifying the TDE 25 at first glance as a distinctly robust heating device in 100 % Trotec brand quality.

The TDE 25 may well be pleasantly small, but it’s far from fragile: Its housing comprises an extremely robust double-wall made of 1.5 mm thick Zincor steel with hardened protective coating for permanent corrosion protection even in case of a damaged coating.

The double-walled construction of the TDE 25 reliably prevents heating of the outer shell. Without any irradiation losses, the powerful axial fan is thus able to discharge the warmth into the room by emitting the hot air flow through the galvanised discharge grille in a targeted manner – if required, via a connectable hot air hose to reach remote areas which do not need to be ventilated, because no oxygen is consumed when heating electrically with the TDE 25.

Its high operational reliability, long lifetime and failure-free continuous operation make the plug-in TDE 25 the first choice for professional renters and all users requiring an almost indestructible heating solution in an easily transportable compact format.

Special equipment features of the electric heating device TDE 25

The housing of the TDE 25 that is equally compact and indestructible with its double wall of 1.5 mm thick Zincor steel is also perfectly equipped for rough conditions on construction sites.
Equally robust and compact – Trotec’s electric heater TDE 25
To show at first glance that the TDE 25 is an original, well-proven professional quality device from Trotec, this electric heater is equipped with a distinctive logo print on both sides.
TDE 25 – professional electric heating at its best
The TDE 25 is a mobile heating solution which due to its compact size can be easily transported and for this purpose features a stable carrying handle made of thermally non-conductive material.

Via the galvanised discharge grille TDE 25 the hot air flow can be blown out in a targeted fashion – if required even to remote areas by means of a connectable hot air hose.
