  5. Power savings (Up to 80% compared to traditional system).
  6. Welded Casings & Silencers with standard painting for Long Life of Fans
  7. Efficient handling Turnkey projects (BOQ, CFD analysis, Design, Manufacturing, Supply, Erection, Commissioning, AMC).

* Much Higher thrust can be achieved based on customers requirements.

BANANA JET FANS VS JET FANS

  1. Traditional Jet Fans have larger losses due to installation issues.
  2. Banana Jet Fan required limited ceiling height.
  3. If ceiling height is not a criteria, bigger diameter jet fans can be used reducing quantity of fans with increased thrust, reducing cabling cost, installation cost along with operational cost.
  4. CFD analysis doesn't cover all the obstacles (cable trays, sign boards, fire fighting piping, columns/beams etc)of the air flow, hence incorrect simulations in most cases

COMPUTATIONAL FLUID DYNAMICS

CFD analysis is an important part in car park ventilation system. CFD is used to predict the flow of air in an underground car park by making a 3-D model and to understand the simulation in various scenarios ( Normal Mode, Fire Mode, CO & CO2 Emission ). The CFD analysis is used as the basics for determining air change rates, volume and air flow direction and placement of fans.

IMPULSE VENTILATION SYSTEM

Impulse ventilation and smoke control systems work by using controllable extract fans that recycle the air while powerful impulse fans control the air flow direction and ensure there are no stagnant air pockets.

Environmental conditions are constantly monitored by the use of CO and smoke detection systems. This environmental data is then fed into the main control panel that adjusts the rate of ventilation accordingly. In the event of a fire, the Jet fans funnel the smoke away from the seat of the fire towards the extract shafts, leaving the car park largely smoke-free. In addition, the powerful fans cool the fire and ensure lower temperatures. Should a fire situation arise, Witt India is the only company whose systems can guarantee the smoke path.
