Expert on-site diagnosis

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.

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.

Expert Cleanroom Certification You Can Trust

OSE delivers exceptional expertise and on-site problem-solving, resulting in a balanced, high-performing certified cleanroom. Their leadership and professionalism make them a pleasure to work with.

  • One Source Environmental (OSE) has consistently delivered excellent results and is a standout talent in the Cleanroom Certification business.

    For example, during a Nano Tech Cleanroom project we were building, the team displayed technical expertise and impressive problem-solving skills, tackling challenges with confidence. The Fan Filter Units had a tight plenum space that varied, forcing them to balance the fan speeds through the control system. When they were finished, the result was a balanced, well-performing, certified cleanroom.
