Increase your comfort & productivity with highly efficient air cooling.....
VENTECH offers state - of - the - art Evaporative Air Cooling Units which are used across industries. Evaporative cooling has proven to be one of the most reliable and economical methods to maintain optimum temperature and humidity. “Ventech” Evaporative Air Cooling Unit is what you need for your evaporative cooling system to perform effectively and economically.
Principle of Evaporative Cooling
100% Fresh Ambient Air is brought in contact with wet surface or mist where it loses its heat and the latent heat of vaporization needed for the water to evaporate is taken from the sensible heat of air. Water then evaporates cooling the air in the process. It is within the cooling media where the process of heat and mass transfer takes place. Since no heat is added or removed from the system, it is therefore, called an adiabatic saturation process and works on the principle of “Cooling is caused by evaporation”. The saturation efficiency of air after passing through the wet section comes to around 85 – 90%. This may, however, please be noted that this being an adiabatic saturation process follows Psychrometry principles wherein the inside DB temperature is a function of outside atmospheric Wet Bulb Temperature and is generally 8- 10 Deg. Celsius over and above the prevailing outside Wet Bulb Temperature.
Why Evaporative Cooling ?
Cost Effective - Dry bulb temperature is brought down through evaporation of water. It is the ideal and most economical method of cooling, therefore Evaporative cooling is cost efficient.
Very low energy consumption – Natural cooling of air and no artificial means is used thereby reducing energy consumption to minimal.
Green Air-conditioning - Conditions the air by evaporative cooling and not mechanical cooling.

TWO STAGE INDIRECT / DIRECT EVAPORATIVE COOLING UNITS (V2C SERIES)
VENTECH has always had affinity towards new technologies and in an endeavour to add value to Environment and making it healthier, has introduced Two Stage Evaporative Coolers which combine indirect with direct evaporative cooling. This is accomplished by passing air inside a heat exchanger that is cooled by evaporation on the outside. In the second stage, the pre-cooled air passes through a water soaked pad and picks up humidity as it cools.
The two-stage evaporative cooling provides air that is cooler than either a direct or indirect single-stage system can provide individually.
