the characters and the advantages of tg no power ventilator

 1. the theory of its running

   our no-power ventilators needn’t electric power

   instead of easily driving the turbine vanes to rotate

   by nature breeze or the temperature difference between

   indoor and outdoor so as to make true the running

   without cost.

   they are really practical and energy-saving products

   without noise and pollution so they can save much

   electricity and labors for users, in order to lower

   production cost clearly, to improve the working

   surrounding of the workshop, to rise the working

   efficiency and even to strengthen the quality of their

   products.

2. the constitutes of the material

   our no power ventilators are made of whole

   stainless steel, galvanized sheet and aluminium which needs no maintenance longer, are anti-acid and anti-erosion by the only once investment.

   tg no power ventilators set up ubc

   bearings which are imported from the usa and can be

   assured for using about 15 years.

3. the values of no power ventilators    

   a. they can exhaust the hot air, waste gas, dust and

      other harmful gas; meanwhile, the fresh air outdoor

      can come into the workshop so as to better the

      working surrounding, to make the workers more

      energetic and to increase the benefits of the

      company.

   b. lower the users’ production costs. because our no

      power ventilators belong to the products which

      need no electric power and other consumes for the

      lifelong time after the only once investment. to a

      large extent, they can lower the users’ product

      costing.

   c. enhance the concept of their safety in workshop.

      first of all, if there is no much harmful gas in

      workshop, the air can ventilate normally so that

      they needn’t to worry about the dangerous accidents

caused by bombing or mistakenly using the electric

power.           

      secondly, in case there happens the fire in workshop,

      our roof turbine ventilators on the roof can make the

      smoke indoor flow out more quickly, at the

      same time which can bring out more time for the victims to

      escape and reduce the loss by the accident.

   d. they can demonstrate the strength and the

      humanization management of the enterprise, enhance

      the "people oriented" principle of the modern

      enterprises and make a show of the time’s colorful

      image.

   e. beautify our living and working surrounding. these

      no power ventilators are possessed with an attractive

      appearance, so they can play their part in

beautifying the surrounding.

the quantity for installing our ventilators:  

(references: the ventilating times of the different buildings)

 

the ventilating cube＝the cube of the building × the ventilating times

 

ventilating cube 

installing quantity = ----------------------------------

                                    ventilating cube／hr 

 

                                     

for example:

there is a building which is 50m length, 12m width and 6m height. the difference in temperature between indoor and outdoor is  10℃, and the wind speed is 9.6km／hr. moreover the ventilating times of the casting factory according to the standard material is between 10 to 30 times per hour. so the ventilating cube is

(50×12×6) ×10 times／hr = 36000cube／hr .

 

3600cbm/hr

---------------------------------------------------------------------------=14.6(units)              2458cbm/hr（according to the different model 880/500/300）

 

so we’d better install 15 units’ ventilators for the workshop.
