How Our Adherence to Environmental Controls Fosters Our Success
Successful data recovery depends on far more than technical skill. The tools you employ also need to be suited to the job, and so does the environment you operate in.
ISO 5 Class 100 Clean Room Data Recovery
At TTR Data recovery, our adherence to ISO 5 Certified Clean room Data Recovery standards gives us the ability to operate more precisely and minimize risks that could further compromise media hardware or the information it contains. By keeping our recovery and repair facilities laboratory-sterile, we’re able to perform operations that preserve the integrity of your data.

What We offer:
Full-Scale, Certified Cleanroom Environments
Our cleanrooms exceed ISO 5 Class 100 standards. We control factors like temperature, humidity, exposure and air particulate levels to minimize your media’s exposure to hazards when it’s in its most vulnerable state.
In addition to helping us improve data recovery rates, our exclusive use of certified cleanrooms lets our clients maintain higher standards. When we’re performing recovery operations for federal agencies, like NASA or the U.S. Army, our rigorous attention to detail helps these entities ensure their own operational compliance.
What is a Clean Room
Industries engaged in manufacture and research mostly use a clean room, such as those manufacturing semiconductors, bio-technology, precision electronics, and medical devices. Devices and electronic components like computer hard drives and silicon chips are sensitive to microscopic dust and contamination can render these devices useless. As such, keeping these contaminants controlled is not possible without a clean room.
A clean room is a facility designed to control temperature and humidity, and keep airborne particles like dust and airborne microorganisms at an extremely low levels through air filtration and employing best practices like wearing protective clothing including face masks and gloves.
A clean room need not be an entire room, it can be as small as bench or as large as a stadium. Clean rooms can also be permanent or portable.
To keep the air free of contaminants, clean rooms employ either HEPA or ULPA filters using either of two air flow techniques: (1) laminar — or unidirectional, directs filtered air downward or horizontally in a straight path towards the filters, (2) turbulent — or non-unidirectional, uses laminar air flow, nonspecific velocity filters to move the airborne particles through the filters. However, there is no such thing as zero particle environment.

Cleanroom Classification
Clean room classification is governed by the International Organization for Standardization or ISO. A clean room classification depends on the amount and size of particles permitted in the air, or the level of air purity. The clean room classification needed in constructing a clean room would depend on several factors including the type of industry, sources of contamination, and size of particle that needs to be filtered out.
ISO 14644-1, which superseded US Federal Standard 209E, classifies clean rooms depending on the size and number of particle per cubic meter of airspace. The Federal Standard 209 classifies clean room into Class 1, Class 10, Class 100, Class 1,000, Class 10,000, and Class 100,000. A Class 100 Clean Room limits the count to less than 100 particles of 0.5 microns per cubic foot of air. To put things in perspective, an ordinary room air is class 1,000,000 or ISO 9.

Continuously-Audited Cleanroom Facilities
Cleanrooms depend on numerous systems for proper function. We strictly audit our control mechanisms in accordance with annual ISO requirements, but we also conduct more-frequent quality checks to prevent mishaps in the interim. TTR Data Recovery facilities undergo continuous monitoring and efficacy verification for:
- Airborne particulate levels and sizing,
- Biological and other forms of contamination,
- Containment and filter leakage,
- Air pressure and airflow variation, and
- Climate control.
Our facilities also employ meticulous quality control and risk response systems. Even in the unlikely event that we experience cleanroom problems, you can rely on the fact that we won’t expose your hardware to them.
Continuously-Audited Cleanroom Facilities
We don’t simply trust the suitability of our facilities up to ISO standards. We’ve also solicited approval and advice from hard drive, flash media, enclosure and NAS manufacturers to verify whether our cleanrooms are up to their high standards. What we discovered may surprise you.
The ISO-5 Class 100 data recovery standards we maintain are actually equivalent or better than the conditions your media was most likely created in. This sets us apart from the vast majority of our competitors.
Why Does Cleanliness Matter When Recovering Sensitive Data
Closed media seems fairly rugged. It doesn't take much, however, to permanently corrupt a hard drive or other delicate storage devices once it's been opened for repair.
When you’re storing hundreds of gigabytes within an inch’s worth of space using components on the atomic scale, size definitely matters. A tiny speck of dirt that the human eye can’t even see may irreversibly damage microscopic electrical contacts, magnetic storage sectors or other common components. Excessive moisture or electrostatic shock can irrecoverably damage formerly-sealed circuitry.
Clean-room Data recovery services that fail to maintain cleanroom standards may return your media in a worse state than it was in to begin with. Even worse, the problem may not appear until you least expect it.
With TTR Data Recovery, you never have to take unnecessary risks. Instead, entrust your devices to one of the only U.S. companies that’s actually qualified to perform delicate work inside them. Contact us today.
