EcoCool Evaporative Cooling Pad uses the simple principle of Cooling by evaporation i.e. passing hot fresh air through the wet and cool surface to bring temperatures down.

Sensible Heat is thereby changed to Latent Heat and Fresh Air leaving the pads is humidified and cold.

The EcoCool Evaporative Cooling Pads are saturated with water, sprayed onto it through prefixed channels.

Fresh Air, which is warm or hot, is blown (with the help of a fan) through the wet EcoCool Pad. The water evaporates when it comes in contact with the warm/hot air, thus cooling as well as humidifying the air entering the area.... shop floor and industrial premises, Greenhouses, Poultry houses.

Ecofriendly and economic, EcoCool provides the ideal media to keep the temperature low in industrial, commercial, and residential areas, poultry farms, hatcheries, livestock areas, greenhouses, and other agricultural areas.

The EcoFresh Enthalpy / Energy Recovery Wheel, which recovers total energy (sensible as well as latent), assists in meeting all the requirements of Indoor Air Quality (IAQ), humidity control and energy saving.

DRI is proudly the world's largest manufacturer of desiccant coated aluminium substrate Energy Recovery Wheels and has an installation history of 25+ years. It also has the largest installed base of such wheels all over the world in the most iconic buildings.

DRI offers the Highest Recovery Enthalpy Wheels in the world (Aluminum substrate coated with a choice of desiccants). These are incorporated into a Fresh Air Handing Unit or Energy Recovery Ventilator. In some cases, the wheel may be installed to stand along with ducts.

Incorporation of EcoFresh Heat Wheels into the air-conditioning system means more outdoor air at lower energy cost (reduced loads).

Total Energy Recovery Wheels may also known in the industry as Energy Conservation Wheels, Heat Wheels, Enthalpy wheels or Sorption Wheels. Sensible only recovery Wheels are also referred to as Condensation Wheels. Hygroscopic recovery wheels have latent efficiency much lower than sorption wheels.

All DRI energy recovery wheels are certified. Eurovent certification and all AHRI program certification details are available on the website, in catalogs and on writing to us.

We offer various diameters and depth of the rotors incorporated into cassettes. Rotors and Cassettes up-to a certain diameter are monolithic as a standard.

Higher diameters on account of handling and shipping are in half moon configuration as a standard. Customization of cassettes: dimensions, construction, segmentation and material of cassette construction for specific project requirements is possible. Please contact us. Both vertical and horizontal cassettes are available. Replacement wheels of all makes are also possible and available in easy retrofit options.

DRI is the world's leading independent desiccant rotor and cassette manufacturer. DRI now has an installed base of hundreds of thousands of desiccant rotors on all continents over the last 23 + years. We are a reliable and trusted partner globally with over 40 years of experience in environmental control solutions.

Our "Ecodry" desiccant rotors , are top-of-the-line in performance and are available in a variety of combinations of substrates and desiccants. We also offer desiccant rotors/wheels for replacement in existing systems. We have the ability to manufacture these rotors in any diameter and depth that also with very precise dimensions, which is a must for replacement jobs. The rotors are highly adsorbent, non-toxic, non-flammable, and fully water washable. The media is pH neutral, having in-situ synthesized metal silicate desiccant on an inert inorganic fiber substrate. The active desiccant material is at least 80% of the total media weight. The surface of the media is edge hardened to ensure a smooth surface, thereby increasing rotor as well as seal life. Our standard rotors have a perimeter flange to allow greater durability and to roll on the ground without damage. The rim of the desiccant rotors is in stainless steel as a standard, as a large part of the applications are in the food and pharmaceutical industry.

We have multiple desiccant rotor options. Our standard MH range is used for the majority of dehumidification applications. We have an LH / DHP1 range for very low dew point requirements, such as in the plastics industry and lithium cell/battery applications. We have another range for low-temperature regeneration. Also for commercial fresh air treatment applications, we have a patented product, a passive desiccant rotor regenerated based on room return air.

On the performance side, our desiccant rotors are better than any other media in the marketplace, especially when it comes to critical low dew point requirements.

Our desiccant rotors have unique advantages over everyone else-they are pH neutral. We do not use any acid during the media preparation or any burn-off process during manufacturing, hence the media is comparatively much stronger.

For commercial dehumidification applications, we supply unique G3MA "True Passive Dehumidification" wheels which allow substantial moisture removal through dehumidification of the fresh air being supplied to the room.

The unique G3MA "Passive" Desiccant Dehumidification Wheel (Patented) has the ability to be regenerated with the 50% RH room return air allowing for substantial moisture removal through dehumidification of the fresh air being supplied to the room.

• Average removal around 14 gr/lb
• High-performance in-situ synthesized desiccant (wheel)
• Fully water washable
• 100% non-flammable
• Removes moisture from a saturated air stream without heat / thermal regeneration

''EcoDry'' Desiccant Rotors

• The desiccant honeycomb rotor media shall be adsorbent, non toxic, non flammable, fully water washable. The substrate of the rotor shall not be made from asbestos or any synthetic material, and shall not have any toxic desiccants impregnated like lithium chloride, etc.
• The desiccant media shall be pH natural
• The desiccant media shall have in-situ synthesized metal silicate desiccant on an inert inorganic fiber substrate
• The active desiccant material shall be at least 80% of the media weight, so as to ensure high performance and minimal heat carryover
• The net organics in the honeycomb media shall not exceed 2%
• The desiccant rotor shall have integral long-life bearings supported by a simple fixed shaft design to allow a simple slide out of the rotor/bed
• The desiccant dehumidification media shall have a perimeter flange which should encircle the entire perimeter to allow greater durability and to roll the rotor on the ground, without damage. The perimeter flange should be smooth and consistent to serve as a perimeter seal surface, thus ensuring a long life for the perimeter seal, without being cut, torn, or otherwise damaged
