Updating Your Cleanroom the Right Way

Updating Your Cleanroom the Right Way

Updating your cleanroom can be daunting. After all, there are so many factors that need to be considered when it comes to any change to the cleanroom environment. You have to consider the specification you need to meet, cost, durability, and maintenance requirements of additions or replacements. But investing in some smart upgrades can really improve the cleanliness, ease of maintenance, efficiency, and ergonomics of your cleanroom space.

LED Lights

LED lighting is a no-brainer when it comes to upgrading your cleanroom. When compared with fluorescent lighting it’s easy to see why: LED lights are very efficient, emit little heat, and require little maintenance, whereas fluorescent lights are fragile and need replacing often. LEDs have the longest lifespan of any commercially available light source, which makes them worth investing in.

LED lighting also beats fluorescent lighting in system efficiency (greater than 50 lumens/watt for LEDs, less than 30 lumens/watt for fluorescents). This is because fluorescent lighting is omnidirectional, emitting light for 360°. Fixture housings are required to redirect fluorescent light to the desired area. LEDs emit light for only 180°, which makes it easy to target light over the desired area–more light actually reaches it.

Panel Repair

If your cleanroom wall panels are damaged, it can be costly to replace them. If the damage isn’t too extensive, it’s possible that panels can be repaired instead of replaced. Repairing damaged panels will improve the aesthetic of your space, but most importantly, it will help maintain the integrity of the cleanroom. Damaged panels could give off particulate matter or allow contaminants to breach the cleanroom.

Vinyl Walls and Ceilings

Vinyl is a smart upgrade for two reasons: cleaning and surface resistance. Vinyl is easy to clean and allows complete removal of particles, in addition to its low particulate emission. Vinyl can also have dissipative or conductive levels of static resistance, making it ESD safe, if that’s something your cleanroom requires.

New Flooring

Due to a variety of factors (gravity, for example), floors are often the dirtiest part of a cleanroom. Just like walls and ceilings, vinyl is also a good flooring choice for the same reasons: chemical resistance, static dissipative or conductive resistance, low particulate emission, and easy cleaning. There are also a variety of other flooring types such as rubber, epoxy coating, urethane, etc., with different characteristics to meet specific purposes. Cleanrooms with heavy vehicle and wear traffic may benefit from ultra-durable rubber flooring, whereas cleanrooms with the need for chemical and stain resistance might require urethane.

There are many ways to spend money while updating your cleanroom, but smart upgrades can help you make the most of your renovations, and your cleanroom. If you’re looking to upgrade your modular cleanroom, be sure to call Angstrom Technology at 888-768-6900 or request a quote online today!

How Much Space Does Your Cleanroom Need?

How Much Space Does Your Cleanroom Need?

One of the most difficult considerations when designing a cleanroom is determining how big or small it needs to be. The goal is to create a cleanroom that is big enough to house operations, but only just. If your cleanroom is considerably larger than you actually need it to be, then you end up wasting a lot of money by keeping that extra space clean as well. If your cleanroom is too small, you won’t reach required production levels and you may not have enough space for all of your machinery. So, how do you decide what your dimensions should be? Here are a few things to take into account:

Clearance

Sure, maybe you have a warehouse with a ton of empty space, but that doesn’t mean you should use all of it for the cleanroom proper. You need to make space allowances for both big HEPA, ULPA, and pre-filters, and you have to consider the installation of the cleanroom itself. Regarding the ceiling, you’ll need at the absolute minimum 6 inches of clearance. Less than that, and you risk starving your filters for air, defeating the purpose of the cleanroom in the first place. We recommend you leave about three feet, if you have the room, to allow for hassle-free changing of your filters. They’re not small, and it will make the job much easier if your employee has a little room to move up there.

When it comes to the walls, we understand that most people like to build against existing walls to conserve space. While this is fine if you absolutely need the space, the installation, and any future maintenance, will be considerably easier if you leave a three-foot perimeter around your cleanroom. This gives you more room to work with, and it makes any future expansions, updates, and even the initial installation go a lot faster.

As a final point on clearance, if you do have a ton of space, it’s important to remember that your cleanroom doesn’t need to take up the entire room. In order to be cost-effective, your cleanroom should be the right size for your operations, and no larger. The more dead space, the more money you pay for no reason.

Machinery

Another key consideration is to estimate exactly how much space any machinery or appliances will take up. If you already have the machinery, we suggest placing it on the floor of your existing area to get an idea of how much space the machines alone will take up, and how far apart they’ll need to be to provide employees safe and convenient access. Any kind of machinery is going to be your biggest factor in determining cleanroom size.

Workers

Once you figure out how much space your machines need, you’ll next have to decide how many workers your operation will require, and how much space they will need to function efficiently within the cleanroom. This should include any workspace required within the cleanroom. If they need to use a table, desk, computer, or chairs, these should all be taken into account when you’re thinking about your cleanroom size. Your employees should have enough room to access the machinery, and comfortably walk from point A to point B, without running into, or interrupting, other workers.

Heat

The final consideration regarding cleanroom space has to do with temperature. While the majority of cleanrooms are modular, any type of cleanroom structure you create will trap heat. This means that if you have a lot of machinery running within the cleanroom or a lot of employees, you may have to factor in a greater amount of space to keep the cleanroom from overheating. Since you can’t – like other rooms – just open a window or door, there has to be enough space built into the design to allow your air conditioner to keep the room at a stable temperature. This is imperative to the function of the cleanroom itself, as well as the productivity of your employees.

It’s also important to note that if you opt for a modular cleanroom, you can always expand along with your production. Modular cleanrooms are highly adjustable, which means you can add on to your existing cleanroom whenever you need the extra space, and if production slows for any reason, it’s relatively simple to bring your cleanroom in a bit. For optimal flexibility, we always advise those in search of a cleanroom to go for a modular option. This way, even if the cleanroom ends up the wrong size, it can easily and affordably be re-fitted for your current business operations.
