Evolving And Expanding Capabilities: Pressure Sensing

Dec 10, 2013

From time to time, Temperature@lert will field customer requests that involve solutions and/or products that are outside of our product line. All of these requests are individually reviewed by Temperature@lert’s specialty solutions team and each team member is aided by their devotion for solving challenges and formulating creative solutions for customized and complex projects. Many projects involve extensive technical consultation and support and each project may even lead to a new innovation. The primary objective is to meet the needs of the customer, but the ability to evolve and adapt is the main ingredient of Temperature@lert’s secret sauce. To quote the old adage, there truly is “always a way” with Temperature@lert.

One of the more recent solution success stories comes from a proactive and enthusiastic pharmaceutical customer. This customer is well-tapped into FDA regulations and requirements, specifically surrounding the recommended pressure differential in clean rooms (as well as ante rooms and biological safety cabinets or BSC’s).

Temperature@lert: Clean Room Pressure Monitoring

In the most basic sense, the goal of pressure differential is to prevent unfiltered air from reaching the BSC. BSC’s are typically housed within clean rooms, which are attached to what an ante room. Beyond the ante room are the hallways/corridors of the pharmaceutical facility.

Bacteria and airborne contaminants are often present in hallways and thus the use of pressure differential drives airflow outward (towards the hallway), as opposed to inward (towards the clean room and BSC.) The air created within the clean room (and the BSC) is filtered and rendered safe for precious medicine preparation and must be remain filtered to ensure safe handling and compounding. By preventing contaminated air from reaching the BSC, the strategy of adjusting pressure differential is an ideal strategy for ensuring safe handling and compounding.

This customer had reiterated that the use of pressure differential sensors are a relatively new FDA requirement and that this requirement will soon be adopted by all clean rooms, specifically within pharmaceutical compounding facilities. Although pressure sensors (and pressure differential indicators) had not been part of the Temperature@lert product offering, Temperature@lert worked directly with the customer over a 2-week period to conceptualize a solution. After a bit of outside-the-box thinking, Temperature@lert designed and developed a customized adapter board to be outfitted with an off-the-shelf differential pressure indicator. This particular solution stood at odds with other pressure differential systems, of which can cost upwards of $4,000 per room.

The customer was highly appreciative of Temperature@lert’s efforts to go beyond the standard product offerings and into a realm of early-adoption implementation. With the customer’s desire to stay ahead of the curve, Temperature@lert recognized to the need to be at the forefront of new FDA requirements for other users.

Temperature@lert continues to encourage early adoption of new (and safer) regulations and requirements and with each new calendar year comes a new challenge.
