Air Innovations posted a new case study concerning the design and manufacture of a medical environmental control system for bioreagents that controls humidity to desiccant levels and maintains a steady temperature in an ISO 8 cleanroom space.
A few of the challenges of this project included system requirements of <3% relative humidity (RH) and 75°F temperature (±2°) for automated packaging of biotherapy reagents, some of which were highly sensitive to moisture and sensitive to heat. In addition, some of the packaged items would include liquids that would introduce an evaporative load into the environment prior to the placement of heat seals. The heat sealing equipment would introduce 400W of heat to the environment.
Additional key specifications included ISO 8 cleanroom HEPA filtration and a stainless steel exterior. All of the specifications determined for the final product were realized and the product meets UL standards.
