PREVENTING CORROSION TO ENSURE EQUIPMENT RELIABILITY
Environmental control programs for data centers and telecom facilities may be lacking a critical protective element; removal of corrosive
gases which can harm sensitive electronics. Neglecting even extremely low levels of corrosive gases can have costly ramifications; downtime,
non-compliance of electronic warranty specifications, ghost signals, circuit board failure and complete failure of electronic components
including hard drives, DIMMs, capacitors, and other components.
Environments that were once considered non-corrosive are now experiencing corrosion-related failures since the introduction of numerous
“lead-free” legislations, such as the European Union (EU) directive “on the Restriction of the use of certain Hazardous Substances” (RoHS).
These legislations require electronic manufacturers to replace lead and other hazardous substances with materials that are proving to be more
susceptible to corrosion. Due to the increasing number of failures using these lead-free materials, electronic manufactures have begun requiring
an ISA Class G1 environment for warranty compliance as described by the International Society of Automation (ISA) Standard 71.04-1985 and
as modified by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Technical Committee TC 9.9 2011 white
paper on gaseous and particulate contamination guidelines for data centers and the International Electronics Manufacturing Initiative (iNEMI)
2012 guidelines for limits of gaseous contamination in data centers and telecommunication rooms.
How can Data Centers and Telecom Facilities Detect Corrosion?
Corrosive gas concentrations are invisible to the human eye (10 times smaller than the smallest particle) and are commonly measured in
parts per billion (ppb). While corrosion is primarily caused by a chemical reaction due to gaseous contamination, heat and moisture can
accelerate this process. Although temperature and humidity can be controlled and monitored through the HVAC system, measuring the
effects of corrosion requires reactivity monitoring, real-time or passive, as prescribed by ISA, ASHRAE, and iNEMI.
Purafil’s reactivity monitoring technologies have been trusted worldwide to help facilities proactively detect corrosion-related problems.
Once a corrosion problem is determined, gas-phase filtration can be added to makeup air handlers, HVAC systems, and CRAC units. Over
the past 40 years, Purafil has provided corrosion control filtration media, filters and filtration systems to help data center and telecom
facilities maintain their electronic equipment warranty compliance, prevent corrosion damage and maintain equipment uptime and reduce
MTBF (mean time between failures) due to corrosive contaminants.
IMPROVING PROCESS RELIABILITY:
Purafil has developed a comprehensive “Assess and Protect” program for data
center and telecom facilities based on our 40 years of expertise in corrosion
control and prevention. Benefits of this program include:

PURAFIL’S ASSESS AND PROTECT PROGRAM is a
comprehensive service that identifies and protects against contaminants that
can cause failures in electronic components and servers. These failures have
become more prevalent in circuit boards, surface mounted components and other
electronics due to changes in electronic equipment manufacturing mandated by
a number of “lead-free” regulations.
Purafil’s full service program helps facilities maintain their warranty compliance
with manufacturers’ air quality requirements through environmental assessments
and clean air product solutions. Let our technical expertise help your facility
maintain equipment reliability, protect valuable data and minimize costly repairs.

AIR QUALITY ASSESSMENT:
We assess your environment to determine the types and levels of corrosive gases in your data centers, server
rooms, switches, I/O devices, power distribution and UPS rooms or other areas housing sensitive electronics. To
the right is an example of corrosion that can form on sensitive electronics, which is typically only visible with the
use of a microscope.
Purafil uses reactivity monitoring (corrosion classification coupons) and real-time
atmospheric monitoring (OnGuard ® 3000) to determine the types and levels of
corrosion. These air quality assessment tools directly corresponds to ISA Standard
71.04-1985 Environmental Conditions for Process Measurement and Control Systems:
Airborne Contaminants (ISA 1985). This standard is currently being revised with updates made
necessary by the numerous RoHS (lead-free) regulations that have been put into law and by
changes recommended by ASHRAE Technical Committee 9.9 on Mission Critical Facilities, Technology
Spaces and Electronic Equipment for application into non-industrial environments. Revisions have
been approved by the ISA S71 Committee and final approval and publication is pending the results
of public review.

PROTECTION SERVICES:
Assuming the HVAC system is already equipped with adequate particulate filtration; gaseous air cleaning can be
used in conjunction with the existing air handling systems. Purafil gas-phase air filters or filtration systems employing
one or more of our adsorbent and/or chemisorbent media can effectively reduce gaseous contaminants to well below
specified guidelines. Properly applied, gaseous air cleaning also has the potential for energy savings.
The type of protection service will depend upon if the air handling system uses outdoor air to provide ventilation,
pressurization, free-colling, or whether Computer Room Air Conditioning (CRAC) units are used for 100%
recirculation. To guide you through some of these applications, below is an outline of various types of air handlers
and applicable protection services.
Computer Room Air Conditioning (CRAC) Units - Almost all CRAC units already have particulate filtration built in that can be retrofitted to use Purafilter
combination particulate and chemical filters. With this type of filter one can maintain the same level of particulate filtration while adding the chemical filtration
required for the control of low levels of gaseous contamination.
PuraGRID filters are also being used in CRAC units to provide control of low-to-moderate levels of gaseous contamination but do not provide particulate
filtration. If this is required, a particulate filter can be supplied in front of the PuraGRID filter.
Makeup (Outdoor, Fresh) Air Handlers - If ventilation and/or pressurization air is being supplied by an existing makeup air handler, chemical filtration
may be added as a retrofit using PuraGRIDs or Purafilters, depending on the capabilities of the air handler and the requirements for air cleaning. If this is not
a practical solution, then one should consider integrating a separate air cleaning section onto the existing makeup air handler(s) incorporating PuraGRIDs,
Purafilters, or MediaPAK modules. If additional air is required for pressurization, a standalone air cleaning system may be required incorporating PuraGRID
filters, MediaPAK modules, or bulk-fill media in deep bed systems.
Airside Economizers - The primary concern in this approach to data center cooling is that outside air contaminants – both particulate and gas-phase – will have
a negative impact on electronics. Data centers located in regions with poor ambient air quality will struggle to maintain an environment conducive for the protection
of sensitive electronic equipment. PuraGRID filters and/or Purafilters can be easily applied in these systems to address this serious contamination issue.

PROTECTION EQUIPMENT:
Purafil is an ISO 9001 quality management system certified manufacturer. Since we engineer and construct our
equipment, media and corrosion monitoring instrumentation we can customize each component to create a builtto-order
package to meet your clean air challenges.
Below are some examples and applications for some of our most popular equipment used in data center and
telecom applications.
Purafil Side Access System (PSA) is designed to remove both particulate and gaseous
pollutants from outdoor (makeup) air for corrosion control. When outdoor air is being delivered
either directly to the data center or indirectly through a mechanical room, the PSA system can
be used as powered or non-powered units designed to control low-to-moderate levels of
gaseous contaminants.
Purafil Positive Pressurization Unit (PPU) is designed to filter low-to-moderate concentrations of outside air
contaminants and supplies cleaned pressurization air to the critical space(s). This unit contains a particulate pre-filter,
two stages of PuraGRID filters or MediaPAK modules, a 90% particulate final filter, a blower section, and an adjustable
damper for control of pressurized air into the air handling system or directly into the data center.
Purafil Corrosive Air Recirculating Air Handler (CA) is an in-room, self-contained unit used to provide
increased amounts of clean recirculated air to areas with low-to-moderate gaseous contaminant levels.
Purafil Deep Bed Scrubber (DBS) is designed for areas where higher levels of contaminant gases are
present and other systems cannot economically provide the filtration required to meet air quality standards.
The DBS provides protection against environmentally induced corrosion and is designed to provide clean
pressurized air to the data center environment.
Under-Floor Air Filtration is the latest innovation for the application of Purafil filters under the perforated
panels on the cold aisles in raised floor systems. The filters can be placed in a customized “tray” under the
perforated panel and fits the dimensions of the existing access floor grid. This type of application can be
considered for installations using 100% recirculation systems.

CONTAMINATION CONTROL PROCESS FLOW
Purafil developed the below flow chart to show the process of monitoring and controlling corrosive contaminants
in a data center.
Although each data center will be different in terms of construction, layout, size, HVAC system components, etc.,
the fundamental steps one takes to establish the risk potential of the data center environment towards the
datacom equipment in use are relatively straightforward.
