Tent-Heating Devices

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.

Doll ceiling ventilators for tents

they are operating by a thermostat controller fully automated below the tent ceiling in the ridge are.
the airflow is precisely adaptable to the tent conditions over the adjustable jalousie shutters on the bottom side.
they don't create any inconvenient draft-effects for people standing below because these devices are regulated by a 5-step-switch, this also has a positive effect concerning acoustic emissions !
quick and easy installation provided by serially-equipped attachment eyes.
protected from dust / humidity and acoustic emission encapsulated external-rotor ventilator motors that guarantee a long durability and safe operation.
the electrical connection is easily provided by the serially-equipped terminal box.
Doll DV devices have been standing the test of time for years in festival tents in aspects like energy-saving + better heat allocation.
efficient temperature-balancing system, that can reduce heating-costs up to 30% at minimal complexity and additionally provides a better heat allocation.

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 !
