Cleanrooms don’t need more air. They need smarter air
Last week I read a review in Energy & Buildings (Guo et al., 2026) covering 235 studies on cleanroom environmental control. One finding stood out. It goes straight to a debate I’ve had with engineers and clients for years: the difference between robustness and reliability. Read more [Picture source: Jo Nelissen…
What actually classifies a cleanroom? Particles or air changes?
A common assumption in cleanroom design is that more air changes means a cleaner area. That is not how classification works. ISO 14644 part 1 defines cleanroom classes from ISO 1 to ISO 9 based on the maximum allowable concentration of airborne particles per cubic metre at specific particle sizes. The air change rate is…
What is the difference between ISO 14644 and GMP classifications?
Many companies have an ISO cleanroom. Far fewer have a GMP-compliant manufacturing environment. The difference isn’t in the walls. It’s in the data integrity, validation and lifecycle control behind them. Read more [Picture source: ABN Cleanroom Technology NV on linkedin.com]

Cleanroom data is the new battleground
Everyone is talking about AI. But AI without trusted data is just expensive fiction. In cleanrooms, we already generate massive amounts of data every single day: temperature, relative humidity, pressure cascades, airflow, energy consumption, alarms, door movements, HVAC performance, filter behavior. The real question is never do we have data? The real question is: can…
AI will not fix poor cleanroom data
Data in cleanrooms is massively underestimated. Not because there is too little data. But because we too often assume that the data is correct, complete and reliable. And that is exactly where the problem starts. AI does not fix bad data. It amplifies it. Read more [Picture source: ABN Cleanroom Technology…
Construction milestone reached for CWS Cleanrooms project in Dublin
ABN Cleanroom Technology, in collaboration with Brecon Cleanroom Systems, has reached a construction milestone for two new ISO Class 5 and ISO Class 7 cleanroom suites for CWS Cleanrooms in Dublin. Read more [Soucre: cleanroomtechnology.com]
Does a dryroom require a different approach than a cleanroom?
The core difference: A #cleanroom controls airborne particle concentration, classified under ISO 14644-1. A #dryroom controls dew point, the temperature at which moisture condenses from the air. Standard cleanroom HVAC systems cannot reach the dew point levels required for battery or advanced materials manufacturing. Read more [Picture source: ABN Cleanroom Technology…
How often should a cleanroom be validated?
Validation frequency is not just a matter of time. It is a matter of control and should always be defined in detail in your validation master plan (VMP). A Validation Master Plan contains a high-level document that outlines the overall strategy, approach and resources for validating systems, equipment and processes. Read…
Do you always need humidity control in a cleanroom?
Humidity control is not explicitly required by cleanroom standards such as ISO14644, which primarily focus on particle concentration. However, in practice, humidity control is often essential to ensure stable and reliable cleanroom operation. Humidity directly affects product quality, equipment performance and operator behaviour. Without proper control, variations can compromise the integrity of the controlled environment….
