HUMIDIN evaporative coolers are available with two types i.e. Single Skin and Double Skin.The corner sheet metal is of cast iron with no insulation while double skin has PVC with Puf insulation that´s CFC free. Working Principle. 

A natural and energy-efficient means of cooling can be provided by evaporating water into air, specially, in low-humidity areas. This very principal is used in the evaporative coolers, i.e. cooling outdoor air by passing it over water-saturated pads, causing the water to evaporate into it. The 15��40�F-cooler air is then directed into the required space, and pushes warmer air out through the given vents. 

While its operation, vents are opened part way to allow warm indoor air to escape as it is replaced by cooled air. I contrast to central air conditioning systems that recirculate the same air; evaporative coolers provide a steady stream of fresh air into the required space. 

Evaporative coolers cost about one-half as much to install as central air conditioners and use about one-quarter as much energy. 

DISCERNIBLE FEATURES:
Panels designed by special software
Standard pre-filters & proper accessibility
Cellulose pads of imported origin
Water tanks with anti-corrosive coatings
'AMCA' certified 'HUMIDIN' made fans
Standard optional accessories 

APPLICATIONS
All the low humidity areas can undoubtedly be served more efficiently by 'Evaporative Coolers'.

Bifurcated Axial Fans are used to keep the motor out of air stream because of the high air/gas/fumes temperatures. Bifurcated Fans are direct driven axial fans where the motor is encased in a central pod to isolate from the flow of air. Bifurcated Fans are ideal for exhausting or re circulating fumes, gases and hot air upto 80�C to 200�C continious operation. 

The Bifurcated Fan have following advantages:
High Temperature Ratings
Isolation of motor from heat or contaminants in the air stream.
Easy to maintain 

DISCERNIBLE FEATURES:
Fan Size: 315 to 1200 mm
Flow rates up to 100000 cmh
Pressures up to 600 Pa 

APPLICATIONS
This fan is mostly placed to exhaust or supply the air of corrosive or hazardous nature. The motor is not in the airflow stream, it thus prevents the hazardous particles available in air.

HUMIDIN Induced Jet Fan is a special designed fan to achieve high impulse throw of discharging air. It consists of an attenuator at the suction and discharge site, pre-designed inlet and outlet guide vanes. The fan units are of high efficiency.
