The Turbowent rotational chimney-pot is a device that use the force of the wind to support a stack effect. The chimney-pot has been designed to be installed on outlets for gravitational exhausting ventilation ducts and the gravitational extraction of superheated (dry) combustion gases from gas-fired equipment in individual houses, blocks and public buildings. Independently of direction, force and kind of wind (horizontal, descending or ascending), the turbine of the chimney-pot always rotates in one direction. The Turbowent axis is encased in an aluminium case in two ball bearings immersed in high-temperature oil with a thermal resistance of 250°C.

Hybrid Turbowent model is new on ventilation market. At first glance, it is a well-known Turbowent rotational chimney-pot; however, this chimney-pot has additionally been equipped with a silent, PLC-controlled engine with a 5W power rating. The chimney-pot acts in dipolar way: when the wind is blowing, natural conditions enable it to achieve the required height of the chimney-pot, the engine does not operate and the chimney-pot operates as a normal Turbowent model. However, when the wind velocity is insufficient for accurate gravitational ventilation – the engine activates and drives the turbine providing appropriate efficiency in this way. In the case where the wind blows with too high a velocity, which would lead to too high an increase in the negative pressure in the chimney duct and too high a flow of extracted air, the chimney-pot engine brakes the turbine to a preset value of its rotational speed. One can say that, independently of outside conditions, the Hybrid Turbowent chimney-pot always turns with almost equal rotational speed, so that performance of the chimney-pot is inside a predetermined range of values. The PLC control enables infinitely variable or stepped adjustment (dependent on the version) of required rotational speed of the turbine and, at the same time, adjustment of the efficiency of the ventilation process. It is also worth emphasisng the fact that the Hybrid Turbowent chimney-pot is quiet and practically maintenance-free and 100% safe, since it is powered by as low a voltage as 10V. Its cost-saving properties are undoubtedly the most important from an individual user’s point of view. Owing to the fact that the Hybrid Turbowent model is driven by a low-power electric engine and only in a no wind situation, which takes place quite rarely, dependent on the height at which a chimney-pot has been installed, its power consumption costs are minimum and amount up to PLN 0.05 per 24 hours of operation (power consumption is 0.12 kWh/24 hrs), for the least favourable situation, i.e. if there were no wind for 24 hours. It is important that one can install Hybrid Turbowent chimney-pot oneself, without help of a professional, and especially because of the fact that all components (PLC-controller, power supply, cables and fixing brackets) are included in delivery. A PLC-controller with display enables one to easily set the required capacity of the chimney-pot by adjusting the rotational speed of the chimney-pot. Naturally, the Hybrid Turbowent chimney-pot can be opened, enabling easy access to chimney duct in order to clean it. The Hybrid Turbowent chimney-pot is not to be used on combustion gas and smoke duct ends.
