Optimizing Performance and Consistency in Controlled Environments
Cleanroom performance optimization is paramount to providing consistent manufacturing yield goals. Cleanrooms and Critical Enclosures are typically designed for a particular purpose or process. Over time, these environments can morph, to include parameters and processes not originally contemplated, oftentimes creating unexpected or undesirable environmental performance issues.
Sometimes age and lack of maintenance cause environmental performance degradation that can transfer to product quality issues. We routinely provide our expertise through facility characterizations and studies that can allow users to get back on track and derive the most from their Cleanroom investments.
We offer on-site diagnosis of Cleanroom environments by a NEBB Certified Technician to evaluate the scope involved in bringing the environment to where the client needs it to be.

Cleanroom Product Compatibility Testing
One Source Environmental has an “in-house” ISO-5 cleanroom that allows us to conduct Cleanroom Product Compatibility Testing for clients looking to ensure their products are compatible for use within ISO Certified environments.
We can vary the performance of this Controlled Environment to mimic any cleanliness class between ISO-5 and ISO-8 for the purpose of introducing a clients’ product and performing various tests to determine environmental impact. Typically, this involves powered equipment or equipment with moving parts that could potentially have a negative impact on particle sensitive environments.


“OSE provides thorough and reliable environmental monitoring of our cleanroom to ensure that we are in compliance with regulatory standards and that we are maintaining the highest levels of cleanliness. Would definitely recommend OSE to any company looking to obtain these types of services.”

Ensure product cleanliness standards
Cleanroom Product Compatibility Testing
We have tested a wide variety of OEM (Original Equipment Manufacturer) products from conveyors to articulating equipment as part of comprehensive test programs to gather information and performance data that helps manufacturers better understand how their products will conform to a variety of Cleanliness requirements.
We can receive, install and operate different equipment configurations, sometimes with the direct assistance or participation of Client Engineers or Technicians within our facility. These projects are always varied, dynamic, challenging, fun and the resultant data oftentimes can be surprising and very informative to the Client.
