Main highlights

Wherever condensation-free heat is needed directly on site and with immediate effect without long air transport routes, the affordable electric heating cannons of the TDS-R series are an optimal choice.
The desired temperature can be dosed as required and infinitely via the integrated thermostat and the heating output can be increased up to 30 kW for maximum selective heat via two-stage connection.
The budget-optimised electric heating cannon TDS 120 R also proves efficiency in terms of construction drying: unlike directly fired gas or oil heating cannons, this electric heater does not consume oxygen, nor does it produce water vapour or combustion exhaust gases during hot air generation - ideal for interior heating, especially for supporting dehumidifiers in accelerated construction drying.
Thanks to 30 kW heating power, the most powerful model in the TDS-R series has comfortable capacity reserves for continuous heating of larger rooms and is therefore particularly suitable for the temperature control of larger building areas.
If desired, the fan can also be used without heating function in pure recirculation mode.
