Dedicated Outdoor Air System

A paradigm shift is happening in the way the HVAC systems of the building have been designed for ages. RH Control is also being looked at critically even in commercial buildings and the air conditioning design is also being modified to address this. Divide and Conquer concept is becoming more and more popular and handling the building's internal moisture load using Ventilation Air is gaining popularity.

DRI Dedicated Outdoor Air Systems (DOAS) are the first choice of designers today for handling the moisture load using Ventilation Air. After having studied almost 20 configurations DRI have the following standard DOAS configurations in their product Range.

Incorporating the highest recovery Enthalpy Wheels, EcoFresh, and patented Passive Desiccant Wheels; this configuration allows the designer to design systems at lower dew points without using a DX system. The system has a unique configuration and uses a Patented Desiccant Wheels which do not require any active energy to regenerate.

DRI DOAS Zenith units are AHRI certified for the performance of cooling coils, Enthalpy Wheels, Sensible Wheels. The casing offered is also AHRI certified for mechanical parameters.

DRI Ultima DOAS can provide fresh air up to 10° C Dew Point using chilled water coils.

Incorporating the highest recovery Enthalpy Wheels, EcoFresh, and Sensible Wheels; this configuration allows the designer to reduce the cooling coil load and also reheat the air without using any active heating method.

DRI DOAS Zenith units are AHRI certified for the performance of cooling coils, Enthalpy Wheels, Sensible Wheels. The casing offered is also AHRI certified for mechanical parameters.

These units are ideal for Hospitals, Hotels, Offices, Airports, Educational Institutes, and all the air-conditioned areas where RH management is required.

The units are manufactured in ISO Certified state of Artfully vertically integrated facility with world-class machinery, units have a unique design to incorporate enthalpy wheels to maximize energy recovery efficiency and minimize cross-contamination.
