Corrosion affects Data Center’s reliability . . .
. . . Monitor Corrosion at your Data Center Smartly!

A combination of humidity, temperature, and various gaseous contaminations can result in corrosion which in turn leads to downtime in Data Centers. Installation and maintenance of effective monitoring devices ensures early detection of corrosion and thus prevents downtime.

Whether it’s ‘Mashaks’ or sacks and bottles of 3000 B.C. or modern-day upholstery, leather goods have always been and will remain a wise investment that lasts a lifetime. But, what does it take to maintain the quality of leather? It’s dehumidification. Yes, modern-day technology can evade moisture accumulation during packaging and storage of leather goods.

Typically there are two types of measurement methods as below:

Corrosion Classification Coupon (CCC):

It provides a direct, quantitative measurement of the overall corrosion potential of an environment. These coupons have two pure metal strips and are placed at strategic locations in the operating environment for a period of 30 days. After 30 days, the coupons are analysed in a laboratory. The thickness of the layer of corrosion which forms on the metal strips determines the severity level as per ISA 71.04-2013 standard. While following manufacturing procedures, it is recommended to maintain the relative humidity at 15% (+/-5%) and temperature at 20°C (+/-2°C).

Real time atmospheric corrosion monitor:

These instruments help to access severity level on real time basis. The measurements are extrapolated in 24 hours for 30 days to know the severity level as per ISA standard. It also measures room temperature, relative humidity and optionally, the differential pressure to give the complete parameters.

Real time atmospheric corrosion monitors can be further classified in two technologies:

  • One is based on Quartz Crystal Microbalance (QCM), which measures the rate of increase of corroded metal sensors mass.
  • The other determines the rate of electrical resistance increase of corroded metal strips.

Corrosivity Levels of Environment as per ISA 71.04 – 2013 Standard

An environment sufficiently well-controlled such that corrosion is not a factor in determining equipment reliability.
An environment in which the effects of corrosion are measurable and corrosion may be a factor in
determining equipment reliability
An environment in which only specially designed and packaged equipment would be expected to survive.
Specifications for equipment in this class are a matter of negotiation between user and supplier.
An environment in which there is a high probability that corrosive attack will occur. These harsh levels should
prompt further evaluation resulting in environmental controls or specially designed and packaged equipment.

Are your Rapid Diagnostic Kits Reliable?

Diagnostic kits need to be reliable and accurate! Quick medical test results and accurate readings undoubtedly play a crucial role in timely diagnosis of many preventable diseases. Thus, manufacturers of diagnostic products need to ensure that processing, storage, assembly and packaging areas follow GMP and environment controls norms. Humidity needs to be continuously and precisely controlled. Humidity and Temperature control needs are very stringent during assembly and packaging of Diagnostic strips, reagents, kits or Lateral Flow Assays (LFA).

The LFA consist of vulnerable test strips which are developed after drying, laminating and assembling several sensitive components. These components include nitrocellulose membranes, sample pads, conjugate pads, adsorbent pad. While following manufacturing procedures, it is recommended to maintain the relative humidity at 15% (+/-5%) and temperature at 20°C (+/-2°C).

Any variation in the relative humidity and temperature can adversely affect the performance of the LFA reagents and can cause false reports.

LFAs are highly sensitive, thus, their process must comply with GMP procedures including the recommended environmental conditions.

Plenty of RDT/LFA/ In-Vitro diagnostic device available in the market to monitor various ailments like:

  • Hepatitis
  • Diabetes
  • Malaria
  • Pregnancy
  • HIV
  • Influenza A/B
  • Thyroid
  • Urinary infections and many more


Bry-Air Solution

A desiccant dehumidifier is an ideal solution, which can maintain the recommended relative humidity inside the manufacturing unit. Bry-Air designs specialized dehumidification system and complies with the most stringent level of GMP and hygiene standards. It helps in maintaining hygienic conditions all year round, regardless of the ambient conditions, at a very low dew point. Bry-Air can provide custom designed package systems with pre-filter, after-filter, precooling (fresh air cooling), post-cooling and bypass arrangement for complete air handling and environment control solutions for each stage of LFA manufacturing.

Compact answer to massive problems


Bry-Air’s FFB series compact Dehumidifiers have the largest range in capacity, 170 cmh to 3000 cmh and thus, can handle ‘massive’ humidity problems in spite of its compact size.

The compact design and relatively small size and weight, makes it easy to install anywhere –inside or outside the controlled area, even outdoors, it can be mounted on the wall/ceiling or placed on the table. Compacts can also be mounted on trolleys for applications where the site is not fixed in the counter flow.

FFB Dehumidifier, the compact and smart desiccant dehumidifier has designed to integrate the “small footprint” with the “ruggedness” of the industrial dehumidifier.

Unlimited Applications:

Typical applications where dehumidifiers, especially, compacts find wide usage are:

  • Diagnostic kit packaging
  • Candy and confectioneries
  • Laboratories
  • Turbine
  • Safety glass
  • Chocolate
  • Pharmaceutical
  • Tea and coffee
  • Leather
  • Spices
  • Spray drying
  • Snacks … and many more
