Advantages of the thrust system

The main advantages are:

1. Saving space

This system saves space because the function of the air ducts in a car park is taken over by thrust ventilators. The thrust ventilators divide up and transport the air over the car park level of air supply point to air removal point. Air ducts are no longer necessary, which saves space.

 

2. Flexible instalment

Several trials have indicated that the place of the thrust ventilators is extremely flexible. The instalment area of the thrust ventilators can vary within a radius of approx. two metres without affecting the proper functioning of the system.

 

3. Complete air mixing

In case of mere air removal, there is no mixing of the removed air. After all, you cannot suck out a candle. It is required to remove at least 2/3 layer of air. By using thrust ventilators, the air on the car park level is mixed perfectly. When using thrust ventilators, no local high concentrations will occur as is the case in the conventional system with ducts.

 

4. Better circulation of the car park

An extensive channel system is often used in order to be sure that no high local concentration of contamination is created in any corner or random area in the car park. Thrust ventilators enable air circulation all over the car park. There are no ‘blind spots’. It is also possible to ventilate in areas with a high detection of CO/LPG and not the entire car park, so a limited amount of energy is temporarily used. It only ventilates when and where necessary.

 

5. Energy saving

Remember that in a system using air ducts, the air is supplied or removed in such a way that requires the air to be pressed through an air channel at a relatively high speed. This requires overcoming resistance, which uses a lot of energy. The thrust ventilator system on the other hand, uses the car park itself as an air channel. The air speed is therefore low and so is the required power.
It should be noted that this comparison only applies to systems using air channels. Directional airing is also possible in combination with an addressable CO/LPG detection system.

 

6. Resistance

If we assume that air channels are not required, then we can conclude that this saves costs. In addition, when using mechanical suction ventilation, this ventilator can be set on lower static pressure because there is no resistance of the air duct. The ventilator only has to conquer the resistance of the discharge tunnel. This can result in a smaller ventilator or a ventilator with a lower speed, also making sound-reducing facilities cheaper. It should be noted that the thrust ventilator system requires more cabling and a larger switch box. Despite these costs, the thrust ventilator system is in many cases cheaper than the conventional system.
