One of the greatest expenses and energy drains in a cleanroom is the HVAC system. Air change rates, pressurization, temperature, and humidity are all monitored to maintain compliance for cleanroom classification. This accounts for about 80% of the energy used, and about 50% of that comes from that fans alone.
With strict guidelines on air quality and regulation, the HVAC systems are typically left to run at full power all the time. If you can reduce the amount of energy used by the HVAC or even shut the system down while the room is not in use (e.g. evenings and weekends), it would result in a significant cost and energy savings. The question is: is it possible to reduce the air change rates without compromising the microbial growth in a sterile environment?
According to research, yes, it might be possible to cut … Read More »
The internal skin of your cleanroom is just as much a barrier from contaminants as are gloves and gowns. Like any barrier, the six sides of your cleanroom are less effective under certain circumstances. Anything that disrupts the smoothness of the surface is a potential contamination hazard. Here are 5 common mistakes people allow inside their cleanrooms.
Compromised surface quality. Any bumps, cracks, scratches, holes, sharp corners, or raised surfaces can be a nightmare to clean. This is not only true of the enclosing structure, but also of countertops and other surfaces found within the room. Keep a close eye on the integrity of flat surfaces, and avoid any work that requires drilling or adding dimensions to the walls or ceiling.
Rivets. These are used to join panels or keep coving or window frames in place. Rivets are very useful in some … Read More »
If you work in a cleanroom, you know it is imperative to follow protocol. To keep contaminates out and protect yourself from toxic substances, you likely use a variety of protective wear like gowns and gloves when you work. Even though gloves provide an excellent barrier between you and what you touch, it is important to take an extra step in safety. Are you washing your hands before and after wearing gloves?
If you’re not, you need to start immediately, and here is why.
Latex gloves are not 100% impenetrable. There is a chance that contaminates from your hands can break the glove barrier. You need clean hands before you even put the gloves on to protect the controlled environment.
Glove residue can break down your tolerance to irritants. Gloves often contain materials that can cause allergies. The allergens rub off on your … Read More »
With the massive amount of energy it takes to power and run a controlled environment, facility managers are scrambling to find ways to make environmentally-friendly choices. We’ve looked at some of the viable options that can make an impact, like recycling, modular cleanrooms, and reusable supplies like sticky mats. When you’re trying to be more green, one of the most obvious places to look is your equipment.
Newer equipment operates more energy-efficiently, but it is also a huge investment. Many facilities simply can’t afford to replace all the old equipment they have. For the equipment that is still fully functional, you may not have to. In many cases, you can retrofit or renovate your equipment to achieve the efficiency of brand new units.
The benefits of upgrading existing equipment are numerous and span far beyond environmental concerns, especially when compared to buying … Read More »
