Cleanroom Lighting Options Explained

Cleanroom Lighting Options Explained

Lighting is an often overlooked but critical part of the cleanroom design process. A poorly lit cleanroom makes work difficult, and a cleanroom with energy inefficient lighting is not sustainably designed and increases energy costs. When designing a cleanroom, choosing lighting options that work for your application can also help control contamination and promote temperature control. Here are the cleanroom lighting options explained to help you in your cleanroom design project.

 

Lighting types

The first lighting option to consider is the type of lighting to use: incandescent, fluorescent, or LED. The chart below briefly explains how each of these types of lighting work, as well as their costs and benefits.

Incandescent

Fluorescent

LED

Incandescent lightbulbs are the traditional lightbulbs. They contain a capsule inside that holds gas around a wire filament, which went electricity is applied, gives off light. They give off heat as well as light, which makes them an inefficient light source and an energy waster. In fact, incandescent bulbs are banned in several countries. In addition to their inefficiency, the light they give off is often not bright or consistent enough for cleanroom applications.  

Fluorescent lights work by ionizing mercury vapor inside a glass tube, which causes the gas’s electrons to emit UV light, which is converted to visible light by the coating of the glass tube. They’re available in the traditional long tubes as well as compact fluorescent lamps (CFLs), which are shaped like incandescent lightbulbs. They are more efficient than incandescent bulbs without being much more expensive and are appropriate for many cleanroom applications.

LED lights, which stands for Light Emitting Diodes, are the most energy-efficient lighting option. They create solid-state lighting by converting electricity directly into light, unlike incandescents and fluorescents. They tend to have a higher initial cost, but their efficiency offsets that cost. LED lighting is often ideal for cleanroom applications, as they do not produce any heat.

 

Also worth considering is natural lighting—you may want to evaluate whether is it possible and practical to incorporate windows into your cleanroom design. Natural light is free, but windows may come with some inefficiencies in terms of temperature control.  

 

Lighting fixture options

There are a variety of fixture options for cleanroom lighting, including

  • Fluorescent ceiling modules — these fluorescent ceiling modules are similar to what you imagine when you picture fluorescent lights: modules that house long fluorescent light tubes. Modules designed specifically for cleanrooms are dust, corrosion, and water resistant and house up to for T8 light tubes.
  • LED light panels — LED light panels provide bright, optimal lighting for cleanroom spaces, without crevices or seams that can house particulate matter or contaminants.
  • LED light strips — LED strips attach directly to the T-bar of the ceiling grid, keeping them out of the way of ceiling filters and allowing for unobstructed air flow.
  • Teardrop lights — teardrop lights are designed for cleanrooms that require whole-ceiling filter coverage, and they minimize obstruction of airflow by hanging down from the ceiling. These are best in cleanrooms with plenty of overhead space since they do hang down from the ceiling.
  • Flow through modules — flow through lighting modules use fluorescent tube lights that are placed directly under the filter system, without blocking airflow. This is a good option when your application requires efficient use of overhead space.

What is a Modular Cleanroom?

What is a Modular Cleanroom?

Modular design is becoming a buzzword in the construction industry, which means it’s also becoming a consideration for companies looking to build or expand, and this includes companies that are designing new cleanrooms. While modular homes might be on your radar (and blocking the right lane of the expressway), modular cleanrooms should be too. So, what is a modular cleanroom?

 

What is modular design?

First, let’s briefly cover modular design. Modular design is an approach to design that separates a system into smaller, self-contained units that can be created individually then combined in various ways to create a whole system. In terms of building and architecture, modular design incorporates universal components that are manufactured in a factory, then assembled on-site into the desired configuration.

 

What is a modular cleanroom?

A modular cleanroom is a cleanroom that is built of pre-fabricated, manufactured components that are assembled to your specifications on-site. These pre-fab components include wall and ceiling panels as well as special features like pass thru chamber panels and air locks.

There are various different design options for modular cleanrooms, depending on your cleanroom’s needs in terms of application and required classification. Modular cleanrooms can be free-standing structures or they can incorporate existing walls and structures within your factory or facility. They can also incorporate existing equipment and HVAC. Modular cleanrooms can have hard walls that resemble traditional construction or soft walls that are somewhat tent-like for greater flexibility and ease of transport.

 

What are the benefits of modular cleanroom design?

There are many benefits of modular cleanrooms, including how quickly they can be built, with minimal disruption in your facility. Modular cleanrooms can also be easily expanded or modified—they can even be taken apart and reconstructed in a new location. And even though the components of modular cleanrooms are somewhat universal, you can still customize a modular cleanroom with a variety of special features and equipment to ensure that it meets your application’s specific needs. These are all immense benefits, and save time and money over most traditionally constructed cleanrooms.

How to Determine Your Cleanroom Design Budget

How to Determine Your Cleanroom Design Budget

Budget: the part of any major project that no one wants to talk about or deal with. Cleanroom design is no exception. Given the very specific and specialized nature of cleanroom design and the unique requirements of each type of cleanroom, it can be difficult to know at the outset of your cleanroom design project what your budget should be. Here are a few things to consider when determining your cleanroom design budget.

 

Type of construction

First of all, are there different types of construction? Yes, when it comes to cleanrooms, you can choose either traditional or modular cleanroom construction. (Read more on traditional vs. modular cleanroom construction here.) Depending on your cleanroom size and application, modular construction may be the more economical choice. If you go the route of traditional construction, you’ll need to include more room in the budget for that.

 

Wall type

For modular cleanrooms, there are a few different wall options, which come at different price points. Softwall cleanrooms are going to have a lower cost than Hardwall or Rigidwall cleanrooms, in most cases. They are a more curtain-like material as opposed to a more traditional wall, which is beneficial for impermanent, small, or lower-classification cleanrooms. However, if your cleanroom must meet a very stringent ISO classification, Hardwall or Rigidwall design may be necessary.

 

Equipment and special features

It comes as no surprise that special equipment and features cost money. If your cleanroom application requires a fume hood, hazardous materials storage cabinetry, a talk-thru panel, a pass-thru chamber, an airlock, an air shower, or any other feature that you wouldn’t find in a normal room, you’ll need to account for that additional cost in your budget.

 

Required classification

As a general rule, the higher the cleanroom class, the higher cost to build and maintain. A biotechnology cleanroom required to meet ISO Class 5 (Fed Std 209E Class 100) standards is going to cost more in terms of materials and equipment, to build and maintain than an ISO Class 8 (Fed Std 209E Class 100,000) storage cleanroom. The higher the classification, the more special features, like those mentioned previously, that the cleanroom will need, the more gowning and personal protective equipment that will be necessary for employees, and the more energy and filters that will be necessary to remove contaminants.

Why You Need a Cleanroom Design Company, Not Just a Contractor

Why You Need a Cleanroom Design Company, Not Just a Contractor

When beginning the cleanroom design process, it may seem like the simplest, easiest, most inexpensive route is to design the cleanroom yourself, then hire your general contractor to build it. After all, you’ve worked with your contractor before and trust them. But in reality, cleanrooms are complex, complicated, and delicate environments that require experience and specialized knowledge to design and build—knowledge and experience that cleanroom design companies have that contractors may not.

Cleanrooms have special design features

Cleanrooms are not regular rooms and have special design concerns. They need to be optimized for laminar air flow to control contamination, they need to be made of materials that are low particulate emitters, and they often have special features like air showers and pass thru chambers that must be specially designed to reduce the amount of contamination that enters a cleanroom. A poorly designed or integrated pass-thru chamber or other design feature will defeat your efforts to control your cleanroom environment and increase your energy cost and consumption, which is why you should leave those features to a specialist.

Cleanrooms require special equipment

Not only do cleanrooms have specialized features, they also require special equipment that must be seamlessly integrated with HVAC, filters, and other systems. Your general contractor might not have knowledge of fume hoods, hazardous material storage, or cleanroom HEPA or ULPA filtration systems, which, if those systems are not installed and integrated properly, could result in contamination or hazardous conditions in your cleanroom

Traditional construction isn’t always the best option

If you hire a contractor to build a room or suite of rooms for you, they’re going to build those rooms. But sometimes, you don’t need a room in the traditional sense—four permanent walls. With cleanrooms particularly, your company’s needs can change as you add or remove equipment, change your processes, or expand your operations.

Modular construction allows you to change your cleanroom when need be. Additionally, certain types of cleanrooms, like storage cleanrooms, may not require the space, control, or rigidity of a traditionally constructed cleanroom, and a softwall cleanroom may suffice. Modular construction can also be more cost-effective than traditional construction because it depreciates at a quicker rate.

What Cleanroom Supplies Do You Need?

What Cleanroom Supplies Do You Need?

Designing and building a cleanroom is one thing, but knowing what you need to buy to keep that cleanroom clean and within the environmental controls for your desired cleanroom classification is another. Here’s a quick rundown on some of the supplies you might need for your cleanroom.

The cleanroom supplies that you need will generally depend on your classification. An ISO Class 1 cleanroom will have the strictest cleanliness and gowning procedures, because that is the most stringent classification, whereas an ISO Class 8 cleanroom may require fewer garments with a more infrequent replacement schedule.

Additionally, your industry and the specific tasks and processes performed in your cleanroom will affect the supplies you need. If your process includes the use of hazardous materials, you’ll need more PPE than a cleanroom of the same ISO or Federal Standard 209E classification. Check out our guide to cleanroom classifications for more information on cleanroom classifications and standards here.
