We are reputed for providing Dedicated Outdoor Air Systems (DOAS) that are loaded with all the advanced configurations ensuring easy and hassle-free operation. We manufacture Dedicated Outdoor Air Systems using the technology that confirms to the international standards.
DRI�s cutting edge R&D has resulted in the development of the ULTIMA DOAS, which allows designers to provide ultimate fresh air ventilation as a single source responsibility.

• DOAS allows designers the DAQ (Divide and Conquer) approach in which DOAS takes care of the fresh air and internal latent load. The parallel system takes care of the internal sensible load.
• Unitary System-single point responsibility to provide Dry Cool Fresh Air in an energy efficient manner
• Constant Supply Air conditions throughout the year
• Intelligent microprocessor controlled DRISMART EMS (Energy Management System)
• Applications include chilled beams and parallel systems (which separately cater for internal sensible load)
• Helps obtain substantial LEED points

How does the ULTIMA Work?
The new DOAS is a unitized Fresh Air Management System integrated through a unique configuration of EcoFresh Heat Wheel, a cooling coil and the innovative G3MA �Passive� desiccant dehumidification wheel (patent pending) and a proprietory controlled embedded logic in the DRISMART EMS.
Ultimate for

• The â��Moisture Centricâ�� tropical countries
• Achieving both RH control and energy recovery

Ideal for

• Hotels / Hospitality
• Office Spaces / IT Offices
• Commercial Spaces / Malls
• Hospitals / Health Care Facilities
• Substaintial Green Building LEED Points for
  • Energy saving (55%) approx
  • Improved IEQ
  • Innovative new technology
