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

Cross-flow heat exchanger exchanges thermal energy from Exhaust air stream of conditioned space to fresh air stream. In flat type heat exchangers two airstreams cross by each other one of these airstreams is exhaust from conditioned air and other air stream is fresh outside air being supplied to ventilated space. A cross-flow heat exchanger is made of thin metal panels, normally aluminium. The thermal energy is exchanged via the panels. A traditional cross-flow heat exchanger has a square cross-section. It has a thermal efficiency of 40–65%.

ERV's has inbuilt high efficiency energy recovery wheel. The energy is recovered from conditioned space exhaust and passed on to fresh air, which is precooled without spending any extra aircon & additional running cost. ERV's are most suitable to cater to low fresh air requirements.

TFA's are meant to cater to large fresh airflow and recovery needs, Treated Fresh Air Units are supplied with various inbuilt options for all HVAC needs, some of the sections/modules/ features are standard modules & others are available as an optional. Heart of the TFA is energy recovery wheel only which recovers Total Enthalpy i.e. both Sensible & latent energy.

Dehumidifiers can be installed as stand alone unit to control humidity in any space requiring humidity control; it can be also completely packaged as per the needs & requirement. The single unit can have inbuilt Precooling section to cater all fresh air needs, Post cooling section for temperature control & moisture control, filtration requirement as complete solution. The units can be designed with Pre/after filters, to handle large airflow requirements & in built condensing units (as an option).
