Medical Devices: Chemical Process Control

A medical device manufacturer came to Air Innovations in need of the proper technology to control close-tolerance cold and dry environments in order to protect its onboard process chemicals. The company brought an initial concept for an environmental control unit to Air Innovations. Our task was to refine the design to meet the customer's performance, serviceability and space specifications, and to prototype, test and ramp up the unit for manufacturing.

Developing the right solution for this client required us to overcome a number of challenges. Because the client sells these units to a worldwide customer base, we had to design a system that could hold temperature and humidity levels across a broad range of differing environmental conditions while operating 24/7 year-round. This included making sure that the cooling coil continued to operate without defrost interruptions well below the point of freezing. And on top of it all, the unit was required to fit into a space equivalent in size to a small microwave.

To some, this would be a seemingly impossible task. To us, it's just part of what we do every day. Air Innovations developed a solution that relies upon two independent cooling coils and process fans operating on an alternating basis managed by software and various sensor inputs to determine switchover intervals.

The product has received FDA approval and is now in full production.
