rooftop turbine powerless ventilator -j9国际官网

the raw material of tg turbine ventilators:

ⅰ) tg turbine ventilators are made of the stainless steel, galvanized sheet and aluminium.

ⅱ) we use the advanced ubc bearings from the usa.

the operating theory of tg turbine ventilators:

the undulating vanes lead to smooth rotation by light wind. the bearings at lower and upper position make smooth turns.

the motility created by the rotation of the vanes brings the hot air, smoke and wet air up to the roof and exhausts them out.

because the turbine is went on rotating, the fresh air outdoor can enter into the room continually so that the room can ventilate conveniently.

the single rotating mechanism will work normally except there is the severe natural damage during 15 years.

our turbine ventilators are possessed with the following traits: no power exhausting, saving energy and money; anti-acid-base, anti-erosion, long-lived used; no noise, no pollution, absolutely environmental protection; improving the air quality, raising working efficiency; conveniently setting up and so on.

they are widely used in chemical industry, light industry, food, medicine, textile and dye, metallurgy, electrical power, construction, tunnel, machine and hotel, cinema and marketplace. recent years later, our products are of demand exceeding supply, and we have our customers through all parts of the country and many foreign countries.

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.
