Cleanroom ceiling tiles are a key player in the big game of keeping cleanrooms free from contamination. These aren't your average ceiling tiles. They're designed with a special purpose in mind: to fight against airborne particles that threaten the purity of the environment. Imagine a warrior shield, but this one protects against microscopic enemies invisible to the naked eye. These tiles work together with other cleanroom systems to make sure the air stays as clean as possible. Whether it's in pharmaceutical labs, electronics manufacturing plants, or hospitals, these tiles are on the front line, ensuring that the air meets strict purity standards.
If you arrive here for the first time, you should know that this article takes part in a series of design considerations for cleanroom HVAC calculations. Previous considerations you should have clear to proceed with the cleanroom air balance are the following:
There are a number of best practice guides and benchmarks for cleanroom air change rates (ACR). Many of which reference charts dating back as far as 20+ years. Most commonly referenced are ISO 146144-4 for hourly air changes and air velocity rates, and Federal Standard 209E for fan filter ceiling coverages.
Getting the specification and design right the first time is very important since HVAC is integrated into a building’s framework, making modifications both time consuming and expensive. Additionally, the design, installation, commissioning, and qualification of cleanroom HVAC systems is one of the top considerations in many industries, particularly for pharmaceutical, biotechnology manufacturing facilities. With these conditions in mind, CAT will develop a custom, compliant system to help maintain each cleanroom’s clean environment by allowing the appropriate volume of clean air to each room at a precise temperature and humidity per your requirements.
