Cosmo House-student Hostel realizes the benefits of Evapoler’s Natural Cooling


Cosmo House is a well-known Boy’s Hostel at Plot 230/230A, Atif Vihar Colony, Near City Law College, Opp. BBD University, Faizabad Road, Lucknow, Uttar Pradesh.

The Challenge

The Cosmo House Boy’s Hostel unit has Third Floor of 2000 Sqft Area. The Hostel owner wanted to ensure his Student and staffs were comfortable, especially during the hot summer months in Lucknow when temperature could reach as high as 42.2°C. The owner initially wanted to go with split air conditioner but seeing the electric load & running cost thereafter started to look for other options of cooling.

The owner was briefed about evaporative cooling system and once he was convinced about benefits like fresh air & low power consumption he decided to go with Evapoler.


The Evapoler is direct evaporative cooling equipment, which works on nature’s evaporative cooling principle with cooling efficiency as high as 90%. 2 Nos. of WIND-180K Machines were installed and the electric load was just 2.2kw as compared to 16.6kw (Air conditioning Load).


The Evapoler machines maintain a temperature difference of 15-20°C between the external and internal temperatures, thus ensuring Cool & comfortable condition on all the work floors throughout the year. An added benefit is that the evapoler machines have reduced the amount of Dust entering to the Hostel Buildingas the machines come with pre-dust filters.
