Articles and papers written by CERTS personnel.

“The Case For Tighter Temperature Control” – Selecting the correct level of temperature control precision requires consideration of more than stored product requirements. Increasing your control precision can yield other operational benefits you may not have considered.

“Limit Control Application In Controlled Environment Room Design” – Proper design and application of limiting devices into the environmental room control system can reduce your risk of loss due to equipment or device failure.

“Selecting a Dehumidification Method” – In controlled environment room design, the dehumidification method selected will have a noticeable impact on first cost, maintenance commitment, installation space requirements, energy cost, and humidity control.

“Risk Reduction in Controlled Environment Room Operation” – Controlled environment room operators bear the risk derived from the probability of system failure. Underlying sources of this risk fall into four categories: defects in materials or workmanship, design defects, service interruption, and normal wear.

“A Basis For Controlled Environment Room Documentation Requirements” – Controlled environment rooms have a long life cycle, with numerous instances of service, repair, modification and validation. These and other factors demand delivery of a comprehensive documentation set, empowering the owner to maintain useful, cost effective ownership of the equipment.

“Controlled Environment Room Minimum Documentation Requirements” – Documentation consists of tables, text, drawings and other descriptive tools illustrating the design, fabrication, operating processes and commissioning of a Controlled Environment Room (CER). Comprehensive CER design and operation information allows the owner to maximize room control and application.

“Benefits Of Enhanced Control Design For Systems With Redundant Cooling” – There are instances where stored material in a walk-in freezer or cold room is so valuable that a redundant cooling system must be included in the design. Beyond redundant cooling units, what features can be included in the purchase specification to maximize benefit from the additional equipment cost?

“Case History: Enhanced Monitoring Averts Freezer Meltdown” – A customer reduces risk of loss in his walk-in freezer by installing advanced monitoring, and keeps his cool in the face of potential disaster.
