Data Centre at a Global Investment Bank

Data Centre at a Global Investment Bank upgrades to AAF Filters and reduces corrosiveness upto 80%

 

Customer Profile:

 

An American Investment Bank with their IT Global Data Center and back-office in Mumbai

 

Current Situation:

 

Malad is a suburb of Mumbai and is known to house several corporate offices (BPO, KPO ITES facilities) for global enterprises. Few of these buildings operate as global data management back-office. Malad was a dumping ground for decades and due to land-scarcity in Mumbai, it was developed as commercial hub as a cheaper alternative to urban Mumbai. The outdoor air is laden with gases emitted due to the gradual degradation of organic material underneath. The untreated fresh air ventilation units carry these gases into the office as well as their data center control rooms. The emitted gases like Hydrogen Sulphide, SOx and NOx are corrosive in nature. These gases, coupled with high humidity, get in contact, react and quickly corrode the metallic surfaces. The data centre control rooms have switches and circuits primarily made of Copper. Given the affinity copper has for these corrosive gases, frequent failure of electronic components is reported.

 

Failure of electronic components can lead to data loss which is a serious threat to the integrity of their back-office operations. The down-time is another challenge in case of an incidental failure of equipment.

 

The existing building ventilation system had a provision for gas-phase filtration system for fresh air intake. The inadequate design of current system was unable to mitigate the failures of electronic components. Customer is looking for a solution which is fail-safe and approached AAF team to study the current indoor and outdoor environment and propose optimal solution for the given situation.

 

Solution Offered:

 

After intensive analysis of site conditions and evaluating the present system, it was observed that there was by-pass in the media cassettes and lesser media bed depth did not allow enough contact time for effective adsorption. The existing system for fresh air intake was replaced with AAF’s PRU (Pressurization Unit) units with 2 pass system, one with SAAFCarb MA and second as SAAFOxidant. The SAAF air purification system was put in pressurization mode.

 

Result:

 

To demonstrate the efficiency of our units, the corrosion coupons were placed outside and just after the RU unit. Given the high corrosion rate, we proposed bi-weekly media sample removal for Remaining Life Analysis and monthly replacement of corrosion coupon for Reactivity Monitoring. The lab results demonstrate that Copper Corrosion rate reduced from 20,000+ A/month to 4.147 A/month wherein the previous system in place could only reduce it to 18277 A/month. The efficacy of AAF solution was effective 80% as against existing~20%.
