All bigger models are based on Inducing or pulling air inside the cooling tower, Forced Draught system exists only for very small design with limited uses. In a Counter Flow Design, the Air is pulled Upward through Downward falling water, Air & Water come in contact with each other in the fill area.
A Counter Flow Design typically offers Lower Fan & Pump power compared to Cross Flow design. Where it lacks in maintenance access it makes up by way of Lower Plan Area Requirement, lower Power Consumption and Economical Cost.
The design is specially suited for operation with Clean Water & Air, like Power Plants, Closed Loop Circuits, City area etc.
Typically Being a Mechanical System, The Fan is Situated at the Top of the Unit driven by a Gearbox connected remotely to a Motor via Driving Shaft. The motor is situated outside the Fan Canopy (and hot humid air) for easy access and maintenance. The air is pulled Upwards by the fan after it has passed through the falling water. The water cooled in this process, is collected in a basin at the bottom of the Cooling Tower.
SVCT designs & installs Counter Flow Cooling Towers with a Variety of Fill Media (Splash as well as Film), varied Height range of 2 feet to 21 feet. Per Cell Waterflow handling is from 50 Cubic Metres per hour of water (or CMH) to 4500 CMH.
Internals like Fills are predominantly of Film Fill or Honeycomb fills though V Bars / Triangular Bars / Grids etc are also common. Film Fill can be used to increase capacity of an Existing Splash Design.
Drift Eliminators are used to Stop excess water droplets from escaping with hot exhaust air.
Ideal for Power Plants, Clean Water Chemical Plants or water with no water contamination / carry over.
