The EcoFresh 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 offers the Highest Recovery Enthalpy Wheels in the world (Aluminum substrate coated with a choice of desiccants).

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

Energy Recovery Wheels also known in the industry as Energy Conservation Wheels, Energy Recovery Wheels, Enthalpy Wheels, Sensible Wheels, Hygroscopic Wheels, Condensation Wheels or Sorption Wheels. These air-to-air Heat Exchangers can recover both sensible (Heat) and latent (Moisture) energy but may use different technologies and offer different efficiencies.

The DRI Treated Fresh Air Units provide a complete solution for IEQ and Energy Saving in a single modular unit with option to add modules for cooling, heating, humidification, high efficiency filtration, mixing, sound attenuation, etc.

Treated Fresh Air Units (TFA) are also sometimes referred to in the industry as Fresh Air Handing Untis FAHU, Fresh Air Units, Rooftop Units, Outdoor Air Handing Units OAHU, Energy Recovery Units or simply Air Handling Units.

DRI Energy Recovery Ventilators are equipped with EcoFresh Energy Recovery Wheels (ERW); capable of recovering more than upto 75% of each sensible and latent energy from the stale exhaust air and transferring it to the fresh outside air. The rotating wheel transfers the sensible and latent energy between the counter flowing exhaust and supply air and in the process preconditions (cool/ heat/ dehumidify/ humidify) the fresh air.

Energy Recovery Ventilators (ERV) are also known in the industry as Heat Recovery Ventilators HRV, Energy Recovery Units ERU and Heat Recovery Units, HRU.

Evaporative Cooling with EcoCool Evaporative Cooling Pads is the ideal and most economical method of cooling.

Evaporative Cooling is the process in which air is cooled by using the heat in the air to evaporate the water from an adjacent surface. A temperature reduction of 10 to 20°C (50-68°F) can be achieved by passing the hot fresh air through the wetted pads.

The temperature reduction depends on the dry bulb and wet bulb temperature of the ambient incoming air, the thickness of the pad (in the direction of the air travel), the geometry of the pad, the air velocity through the pad and provided the proper amount of water is used and distributed evenly so that all of the pads are wet through their depth, height and width. The hotter and drier the incoming air, the higher the temperature reduction, after passing through the wetted EcoCool pads.

DRI Arctic Coolers also called Evaporative Coolers, Industrial Coolers, Commercial Coolers, Air Washers, Swamp Coolers and Industrial Ventilation Coolers,  offer a completely natural way of delivering refreshing cool air. DRI Arctic range of Evaporative cooling units have been specifically designed for the cooling of industrial and commercial buildings.

They are capable of lowering the fresh air dry bulb temperature by 7-12°C, e.g- the air-off temperature from the evaporative cooler for an outside temperature of 40-43°C can be as low as 28-30°C. They allow cool fresh air to be introduced throughout a building and also the stale hot air to be displaced out through openings like windows. Unlike mechanical air-conditioning which continuously cools re-circulated air, Arctic coolers introduced 100% cool fresh air into the space.

DRI Spot Coolers provide an easy and effective method of cooling over heated areas within a larger area, as opposed to providing general cooling by means of a remote cooler fixed at one place.

The Arctic Spot Cooler benefits

Portable Cooling
Durable & reliable
Environment friendly
Economival operation
Comfortable working environment
Easy Maintenance

DRI's EcoDry Rotors and Cassettes are the result of many man- years of in-depth study and research work on countless permutations and combinations of substrates, desiccants and chemical processes. Every aspect of rotor dynamics, behavior, characteristics and physical parameters has been considered to maximize performance, durability and applicability.

Regenerates desiccant without additional energy usage

The unique G3MA “Passive” Desiccant Dehumidification Wheel (patent pending) 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.
