MISSION

Ofering innovative technologies to the beneit of humanity.

VISION

To become a leading enterprise globally by producing

technologies that help humanity to breathe.

%75*75% of the casualties in ire cases occur due to smoke inhalation.

Therefore, exhausting the smoke in enclosed areas with the risk of ire are vital.

Competencies Of The System

Advantages for the investors•Reduces costs by replacing bulky and complex duct systems. It is particularly advantageous for renovation projects.

•Modern aesthetics: Flexible positioning of Jet Fans facilitate modern and aesthetic de-

signing.

•Sleek and regular design: Unlike ductworks the system is more sightly as a whole and cause no obstacles in sight.

Advantages and beneits for planners

•Whether used in new buildings or renova-

tions projects they provide signiicantly lexible positioning.

•There is no need for complex ductworks.

The advantages and beneits for the parking operators;

•Easy to install: Jet fans can be mounted quickly and easily on the roof.

•Hassle-free setup: Mounting the fans may be the inal step of a project which means less overlap with other works.

•Flexible positioning.

The advantages and beneits to the operator•Energy eicient Jet Fan System. Cuts the costs signiicantly by saving energy up to %80. Energy eiciency is facilitated by the smart control unit which is the main focus of the system to control the air movements de-

pending on the alternative needs of the medium.

Unlike duct systems, pressure droppings does not occur in jet fan systems allowing them to operate with a low level of power which means another way of energy saving.

•Customized according to needs: The carbon monoxide (CO) sensor switches the fans on only in the needed areas and only when the need occurs. Predeined areas can be ven-

tilated without employing the whole fans in the system. This feature also helps to reduce the operating costs.

•High air quality: During Jet Fan operation the concentration of the air pollutants re-

main much lower than during the operation of duct systems. During the operation of the fans the air remains in a constant motion which helps the rate of fresh air to increase in all areas in the medium.

•Evacuating the heat and the smoke quickly, Jet Fan Systems prevent costly damages in the ceilings reducing the level and the dura-

tion of temperature they are exposed to.

•Sensitive smoke control, provides optimum safety in the event of a ire and make the ire department’s job easier as Jet Fans evacuate the smoke and the heat rapidly before they spread to other areas of the building.

Calculation Steps For Jet Fans1-CALCULATION OF VOLUME

V = A . h

Where V is the volume, A is the area and h is the height of

the building,

Area = Width x Depth = 40 m x 100 m = 4000 m2

Height = 3 m Volume = 4000 m2 x 3 m = 12000 m3

2-AIR FLOW CALCULATION

Q = V . Ach

Where Q is the Flow, V is the Volume and Ach is the coei-

cient of the air exchange,

a) Daily carbon monoxide (CO) ventilaiton air low,

Ach = 6 times/h,

V = 12000 m3,

Q = 12000 . 6 = 72000 m3/h,

b) Fire event ventilation air low,

Ach = 10 times/h,

V = 12000 m3,

Q = 12000 . 10 = 120000 m3/h

* Minimum Ach value is obtained from BS 7346-7 standards.

Depending on the architectural details higher air eXchange

coeicient values can taken for car parks.

3-FAN SELECTION FOR EXHAUST AND FRESH AIR

VENTILATIONS

A – AIR FLOW

Exhaust Fan (DEF)

DEF = 120000 m3/h x %50 = 60000 m3/h

DEF – 1 = 60000 m3/h DEF – 2 = 60000 m3/h

*The exhaust air low is backed up %50 in accordance with

BS 7346-7.

B- PRESSURE LOSS

Pressure losses caused by shafts, silencers, dampers or lou-

vers are determined by the air speed.

C- FIRE RESISTANCE

Exhoust and jet fans are selected in comliance with TS/EN

12101-3 ire resistance standard.

Fresh Air Fan (THF)

THF = 120.000 m3/h x %60 = 72.000 m3/h

50% - 70% of the exhaust air fans are Flows Considered as the air

low for the fresh air fans.

4- Considering the height of the ceiling and the length of the building jet fans with optimal thrust are slected. Radial jet fans are preferred in one-way operations as they have height advantages.

5- SHAFT SIZING

According to the Air VelocityThe shaft sizes should be calculated as such that the maximum velocity of the air that should pass through the shaft area must be 8 m/sec.

72000 m3/h = 20 m3/sShaft Area=(Air Flow )/Velocity =(20 m3/s)/(8 m/s) =2,5 m2

According to the Fan SizeWhen fans are installed inside the shafts the fan size also must be cosidered, giving priority to the cross-section air velocity.

6- SHAFT DAMPER SIZING

Corresponding to each fan given the air velocity as 8 m/sec a motorized shaft smoke exhaust damper, which facilitates zoning between loors, is selected.

Example:8 m/sec = 28800 m/hIf 2 shafts are to be selected then the Airf Flow for each shft would be 72000 m3/h = 36000 m3/h + 36000 m3/h

Efective Area=(Air Flow )/Velocity =(36000 m3/h)/(28800 m/h) =1,25 m2

7- CFD ANALYSIS

When designing the system all problems that involve the low of the air are analyzed and solved using com-

puter simulation and CFD analysis method.

JETFANS

GENERAL FEATURES

The hardware used in smoke exhaust fans are tested and ceriied to the internaionally recognized AMCA/ANSI standards.

High temperature FTAJF models’ equipments are ire ceriied by internaionally recog-

nized accreditaion organizaions.

Jefans are produced between the diameter ranges of Ø315 mm and Ø560 mm. Depending on the applicaion the fan can be produced as unidirecional or reversible and as suitable for tow speed or variable speed operaions.

THE BODY OF THE FAN

TFAJF type fan’s cassete body is manufactured from ST37 (S235JR) (EN10025) quality steel and all steel parts are protected with polyester powder coaing and hot dipped galvanized casing opionally.

IMPELLER

Adjustable body pitch aerofoil impellers manufactured from special aluminum alloy under internaional standards.

ELECTRIC MOTOR

Three-phase 380V - 50Hz (standard), 400/415/440 V - 50 Hz and manufactured on demand in other voltage and frequencies as well. Class H, S1, IP55 motors are used as standard.

ACCESSORIES

Silencers are used in these series to reduce the noise created by the guide vanes ixed to the body for the purpose of speeding up the air supplied.

INDOOR PARKINGSWith Clean Air

There are axial and/or radial types of Jetfan Systems each with diferent power options.

Jetfans are positioned in a parking as parallel and series, in intervals the distances of whom de-

pend on their thrust and the features of the models, to cover all areas and avoid dead zones in

the parking. The interval distances may also vary according to the architectural structure of the

building.

The thrust Jetfans generate help mobilize large masses of air to reduce levels of CO and other

harmful air pollutants and to assist with the extraction of smoke in the event of a ire.

Jetfans restrict the distribution of smoke and toxic gasses only to the ire region guiding the

smoke out before spreading to other areas.

Once the smoke and the heat is reduced and directed to an exit, the visibility of the ireighters

will be improved and the ire point can be approached as close as 10 meters.

OPERATING PRINCIPLE OF THE JET

Helping humanity to breathe

Considering the volume of the air, the shape and the size of the pariking area and the positions of the shafts in the building the selection and sequencing of the jet fans are designed.

An emergency planning would support the selection of the fans in the project using Computational Fluid Dynamics Analisis which will help us obtain prelimi-nary information simulating all possible emergency

scenaios, form a probable ire event to the evacuation of the exhaust gases, to ind out alternative solutions for the exhaustion of unwanted gases.

To determine the accuracy of Jet fan ventilation system design and to achieve precise positioning of the Jet fans it is necessary to ceate a 3D model and luid dynamics simulation of the parking under a set of given conditions.

Simulation must be designed by means of an internationally recognized softwa-

re such as CFX or CFDesign. As a result it should determine the number and the optimized positions of the Jet fans.
