Presidential TwitterDear Fellow DCI Members

Greetings ! This edition of Twitter is for the period October to

December 2013, I must say , it was the most exciting and

exhilarating quarter of my tenure as DCI President. We had a

very successful mega event, Ventconf 2013 , the 3rd edition of

this conference on Ventilation, and the second for Delhi. This

year the venue was the ultra modern Epicenter in Gurgaon. It

was indeed a pleasure working closely with all the members of

the Ventconf committee which delivered this event to the Industry. I thank the Chairman of

Ventconf 2013, Mr Sushil Chaudhury for the success of this event and indeed to the 300+

delegates who took part in this conference. Many members came up to me to

acknowledged to professional manner in which this conference was conducted in this

superb venue.

Urjavaran Lucknow and Dehradun were also conducted in this quarter. We also had some

Workshops of BIM , Sound & Vibration. You will read all about it, further in this issue.

Next up, is the annual flagship event of ISHRAE, ACREX 2014, which is in Delhi. Please

book the dates 27th Feb to Mar 1st 2014 in your calendar. I am sure you have already

heard from my fellow ACREX committee members regarding this Exhibition. Along with

the exhibition are many interesting workshops on global HVAC issues, given by

International speakers. Don’t Miss them ! Please refer to the back cover of this issue to

know more about it or log on to www.acrex.in

This issue of Twitter discusses the topic of Air based Corrosion in Server rooms and Data

Centres. As India becomes the Server room for the World, this topic is increasingly

relevant and important to tackle, especially in NCR area, NOIDA, GURGAON and DELHI.

Be sure to read through the informative article enclosed, written by Mr Atish Kumar Basak.

Happy Reading !

DCI organized a Painting Competition Program at DAV

Public School, West Patel Nagar, New Delhi on 29th Dec’

2013. Nearly 300 students from Nursery to IIIrd standard

took part in this program & the winning students were

awarded. The Students as well as the School’s faculty

enthusiastically participated in the event. The program was

attended by DCI President Mr. Sanjay Gupta, K-12 Chair

in HVAC&R, i.e. Ventilation. Ever since ISHRAE initiatiated it

in 2011, Ventconf has been known as the only exclusive

conference in the world on ventilation. Ventconf 2013 was a

runaway success with the participation of over 350 delegates

from all over India. The lighting of the lamp was performed by

ISHRAE President Emeritus Dr. Prem C. Jain, National

President Dipak Barma, Ventconf 2013 Chair Sushil K.

Choudhury, Co-chair and Delhi Chapter President Sanjay

Gupta, RD North-1 Sunil Kher, special guest Anoop Kumar

Gupta – Director (Electrical) of Delhi Metro, and Ashok

Virmani – Director and Regional Chair, ASHRAE. In his

welcome address, Sushil Choudhury underlined the fact that

Ventconf has now become an international conference with

both speakers and partners from abroad. Dipak Barma and

Anoop Gupta also addressed the inaugural session, which

concluded with Dr. P.C. Jain’s address. This was followed by

three technical sessions, in which eminent speakers from

India and abroad presented a very informative and interesting

mix of technical papers on High Performance Air Systems (by

Wade Smith from the US), Energy Recovery Ventilation (by

Maija Virta from Finland), Tunnel Ventilation (by Andrea

Valente from Italy), Natural Ventilation (by Architect Dr. Vinod

Gupta), Kitchen Ventilation (by Jordan Baker from the US),

Power Plant Ventilation (by Prabir Sen) and Design of Fire

Safe Buildings (by Sandeep Goel).

To underline the importance of ventilation in the design of fire

safe buildings, an informative and interactive panel discussion

was conducted in the afternoon with an expert panel

comprising of UP Fire Chief Aman Sharma, Architect Dr.

Vinod Gupta, Senior Consultant S. Srinivas, and Sanjay Batra

from Medicity. The panel discussion was moderated by

Sandeep Goel, Founder Director – Proion Consultants.

Ventconf 2013 was supported by six partners – Eurovent

Certification, Greenheck, Humidin, Nicotra, Sevcon-LTI and

Systemair. A concurrent catalog show was organized with

eight catalog partners – Air Flow, Blowtech, Crystal Air

Systems, Desiccant Rotors, Havells, Marathon Electric,

Mridul Engineers and Rotomotive Powerdrives. All 14

partners displayed their latest products and services through

catalogs – both print and electronic. It was a well planned and

well attended event. The success of this annual conference is
