MACHINE TYPES

  • Dual Evaporative Unit
  • Direct Evaporative Unit (DEU)
  • Indirect Evaporative Unit (IEU)

HOW IT WORKS

Fresh outdoor air is drawn by a high efficiency fan through suitable filters and passed over the large surface area of a cooling coil which carries primary coolant being cooled through a Sensible Heat Rejection Unit, working in a heat-removal mode. Thereby, it cools the incoming air during summer from ambient dry air of 42-44°C to 30-32°C without directly adding any water vapor to the incoming air.
This pre-cooled & clean air then passes through high surface air mass exchanger made of cellulose substrate, wetted by continuously flowing water thus providing direct evaporative cooling . This lowers the temperature from around 32°C to 18— 20°C which is being finally supplied to the space to be cooled through air distribution system.
Hence, this unique technology enables to provide supply air temperatures lower than the wet bulb temperature & goes even below 20°C during peak summer/ dry season. Since it is based on 100% fresh, filtered air, hence it provides better inside conditions than Air- conditioning. However, being an evaporative cooling concept, it remains to be less effective during few days in an year when atmosphere is hot & humid.

THE KEY COMPONENTS

  • Modular Cabinet
  • Air Filters
  • Heat Exchanger Coils
  • Humidification Section
  • Water Recirculation Pump & Tank
  • Blower with Motor
  •  SHR Unit
  • SHR Unit Pump 'Air Distribution System (if applicable)

SALIENT FEATURES

  • Comfort cooling (Green Conditioning) with supply air temperatures as low as 18°C & room temperatures between 22 - 24°C, with humidity between 55 —65 % & that too under peak summer conditions*
  • Significantly low power consumption. It is now possible to lower the power consumption levels even up to 20% of conventional air conditioners
  • Low noise levels
  • Maintains excellent indoor air quality (IAQ)
  • Prevents pollutants from entering the space to a very large extent by providing filtrations of desired level & stages
  • Delivers continuous 100% fresh filtered & treated air thus ensuring healthy & fresh inside atmosphere
  • Provides positive pressure thus eliminating any kind of dust or pollutant infiltration
  • Replaces any kind of odor / smoke being generated within the conditioned area with 100% cool fresh air
  • Provides quick cooling since it works on 100% displacement of air
  • Reduces the propagation of airborne diseases since there is no recirculation of air
  • No requirement to make airtight partitions in the conditioned areas. Since it works on 100% fresh air, thus improves conditions in the leak out areas
  • Eco- friendly, efficient and economical to operate
  • Optional UV lights & Inbuilt Ozonizer provides continuous fresh & bacteria free air
  • Optional BMS Compatibility. Multiple units can be controlled & operated through PC & temperature & RH Data could be recorded

ADVANTAGES

  • Lowest power consumption. As low as only 20% of conventional AC system.
  • Practically, 'Zero' maintenance, no expensive repairs
  • Lowest down time
  • No compressor, nor 03 Depleting substances like refrigerant gas
  • No recirculation, hence better IAQ.
  • Works on 100% fresh air, hence no air borne disease.
  • Convenience of installation
  • Room conditions and indoor air quality within comfort limits & even better than normal AC system during peak summer conditions.

DIS - ADVANTAGES

  • Since it works on ambient conditions, it is recommended only for dry & moderate climates
  • Inside comfort levels not comparable toAC system during few days in a year when it is hot & humid & is limited upto 28 — 30° C.
