For the heating of tents we are manufacturing mobile devices as well as devices in container-/trailer- design in each case in combination with a specifically matched set of tent-heating accessories, as there are Doll- blow-out towers (utility patent / patent), specially designed hot-air tubes and also ceiling-ventilators for air-recirculation to the floor area.
Doll tent blow-out towers for an equal heat-allocation in party-, trade-fair-, festival- and club-tents.
The systems are providing in combination with mobile Doll Air-heaters a noticeable homogeneous and comfortable heat allocation in the tent, th towers are height-adjustable to the individual construction of the tent. The heat allocation is adjustable vertically and horizontally.

The heating of large and high festival– and trade fair-tents requires an enormous amount of energy. Based on the law of physics, heat rises up and forms a heat cushion below the tent's ceiling – which is normally badly insulated, the pent-up air is getting lost transmission to the outside and in the bottom floor area is a lack of warmth.
Conventional ceiling ventilators are providing no help in tents because they don't move the air with enough directed kinetic energy, that way the downward air-flow tears off far from the ground and the heat rises up again.
As recently as the special Doll- DV 500 devices are offering a systematic feedback of heat in the floor area and are allowing utilisation of pent-up heat, before it gets lost through the roof – and this without any draft effects! In the summer time they work as a fully-automatic aeration system !
