Most Common Cleanroom Design Problems

Most Common Cleanroom Design Problems

by | Aug 9, 2018 | Cleanroom Design

Cleanrooms present a lot of unique challenges in terms of design because they have very specific requirements they have to meet. If you’re meeting your desired ISO standard, you might feel like your design is good enough, but the truth is that there are a lot of common issues that companies face when designing cleanrooms. Here are some of the most common cleanroom design problems we see:

Inefficient placement

One of the biggest issues with cleanroom design is inefficiency. If your design doesn’t support your processes, it’s going to cause problems. Consider the various tasks and processes that go on in your cleanroom. Is someone always getting in someone else’s way because of where there workstations or supplies are located? Are there too many processes sharing one sink, causing a bottleneck? Are there drawers or cabinets that you can’t fully open because they’re too close to a wall or door? All of those problems can cause major inefficiency and can be avoided with good design.

Maze-like walkways

The whole point of a maze is inefficiency, it takes a long time to get through a relatively short distance because you have to twist and turn and wind around obstacles. But your cleanroom shouldn’t be a labyrinth. If employees have to walk through narrow paths, wind around oddly placed workstations, or bump into each other constantly to get to the door, their workstations, the sink, or the fire extinguisher, you will have massive safety problems on your hands, not to mention a lot of wasted time and motion on the part of the cleanroom techs.

Poor ventilation

Good ventilation is necessary for any space to be comfortable, but it’s especially crucial in a cleanroom, where you’re trying to maintain a controlled environment with limited particles and contaminants. Additionally, in cleanrooms where hazardous materials are used, good ventilation is a necessary safety concern to ensure the well-being of workers.

Unable to maintain temperature

No one wants to work in a room that’s too hot and stuffy or freezing cold, so for the same of employees comfort and morale, a cleanroom that is a comfortable temperature matters. It’s vital too that your cleanroom can maintain its desired temperature to protect the products, materials, and chemicals stored in it, as they can be sensitive to temperature, and to prevent the growth of mold and bacteria that can compromise the cleanroom environment. This could be a problem with your HVAC, thermostat, or insulation, so be sure to select those things wisely and perform regular maintenance checks.

Good design is the first step to having a well-functioning cleanroom. If you recognize some of the issues we mentioned in your current cleanroom, it’s probably time for a redesign. There are a few things you can do in the meantime to work with the layout you have and increase efficiency, such as rearranging movable cleanroom furniture, moving processes that don’t require a controlled environment to a new area, or simply cleaning out any tools, materials, or storage that is no longer necessary.

How are Cleanrooms Validated?

How are Cleanrooms Validated?

by | Aug 8, 2018 | Cleanrooms

Validation is an important process for any cleanroom. It serves to ensure that the cleanroom is properly installed and designed for its intended ISO classification and that all of the components (facility, environment, equipment) meet regulatory requirements and other defined standards. So what’s the cleanroom validation process?

Most often, cleanrooms are validated by third-party validation agencies. This entails a thorough inspection and several tests, whereafter the cleanroom is certified to a specific class indicating its level of control, usually to an ISO14544-1 class.

Validation has several phases, beginning with design qualification, and ending in final certification.  Some of the tests performed in these phases include airflow volume and velocity tests, HEPA/ULPA filter leak testing, air movement visualization (smoke testing), room pressurization, room recovery, airborne particle count tests, relative humidity, temperature, and other testing conditions.

Certification consists of three main phases. Installation qualification is also referred to as Phase 1 or “As built” testing. Testing is performed with all services connected and working, but no materials, production equipment, or employees present, proving that the equipment is correctly installed

Phase 2 is the operational qualification or “At rest” testing. Testing occurs when equipment is installed but not operating, and no employees are present. This proves that the equipment works properly to achieve the required environmental conditions.

Phase 3 is what is referred to as performance qualification. In this phase, testing is performed with all equipment installed and operating and employees performing their regular work duties and tasks. This testing proves that the cleanroom has the required operational performance for the cleanroom application.

Once initial certification is complete, it is important to regularly recertify to ensure that your cleanroom continues to operate as it did when it was built.  At a minimum, annual certification is recommended. Depending on industry and product, semi-annual or even quarterly certification may be required.

Cleanroom HVAC Systems Explained

Cleanroom HVAC Systems Explained

by | Jul 25, 2018 | Air Circulation

In cleanrooms, air is crucial – how it’s filtered, how it’s heated and cooled, and how it’s circulated. Because of this, knowing how HVAC and filters work together is crucial to maintaining cleanroom air decontamination and meeting cleanroom standards. Before you install a new cleanroom, here’s what you need to know about your cleanroom’s HVAC system:

Dedicated vs. Integrated HVAC

When it comes to cleanroom HVAC systems, the first decision is whether to have a dedicated HVAC system or to incorporate your building’s existing HVAC. This depends on the necessary level of environmental control, the size of your cleanroom, and the other energy requirements of your facilities. Using an existing HVAC system can help you save money at the outset, but for very large cleanrooms or factories, a dedicated system might be more efficient and keep a reasonable load on each system so that they can run efficiently. Additionally, while you can combine a filtration system with an existing HVAC system very efficiently, for extremely stringent cleanroom standards, dedicated HVAC may be your best bet.

Filtration systems

Filtration is also an important consideration here. There are three basic types of filters used in cleanrooms: prefilters, HEPA filters, and ULPA filters. Prefilters are used with both HEPA and ULPA filters as a first step in the filtration process, removing large particles.

HEPA filters are High-Efficiency Particulate Air filters, and they filter out 99.99 percent of particles 0.3µm or larger.

ULPA filters are Ultra Low Particulate Air filters, and filter out 99.999 percent of particles larger than 0.12µm.

Purity Testing

Once your HVAC and filtration systems are in place, you must regularly test the air purity of your system. Testing should occur initially in three phases: as-built testing (when all services are connected and working), at rest (when all equipment is installed and in place), and performance qualification (occurring regularly while the cleanroom is in operation).

Hardwall vs. Softwall Cleanrooms

Hardwall vs. Softwall Cleanrooms

by | Jul 11, 2018 | Cleanrooms

If you’ve been looking into cleanroom options for your company, you may have come across the terminology “hardwall” and “softwall” in reference to different types of cleanrooms. But, what’s the difference in those types of cleanrooms? And how do you know which is right for your application? Let us break it down for you.

Hardwall Cleanrooms

Hardwall cleanrooms mimic traditional construction in that they have solid walls (hence the name) but retain greater flexibility. The benefits of hardwall cleanrooms are numerous:

  • Existing HVAC incorporation—hardwall cleanrooms can utilize your building’s existing HVAC while maintaining your cleanroom standards.
  • Mounted equipment—hardwall cleanrooms can be designed around already mounted equipment that is floor mounted or ceiling mounted.
  • Strong environmental control—hardwall cleanrooms allow you total control over your cleanroom environment from static and temperature to particle decontamination to meet even ISO Class 1 standards
  • Able to modify—hardwall cleanrooms have a modular design that makes it easy to expand or upgrade as your cleanroom needs change.     
  • Durable—hardwall cleanrooms have a durable frame and strong ceiling grid, so they last for a long time and never sag.

Hardwall cleanrooms are excellent for large cleanrooms and traditional cleanroom applications and can work well when strict environmental control is necessary.

Softwall Cleanrooms

Softwall cleanrooms function essentially like a tent, they are made of flexible material, unlike traditional walls, and can be freestanding or suspended from your existing structure. Some of the benefits of softwall cleanrooms include:

  • Affordability—softwall cleanrooms require minimal materials and are simple in design, making them a budget-friendly option.
  • Customizable—softwall cleanrooms are super flexible and can easily be customized to your application with the necessary HEPA or ULPA filters or required door type.
  • Flexible—softwall cleanrooms are light and can be easily moved, whether freestanding or attached to your existing structure.
  • Easy to install—softwall cleanrooms can be installed in just a few hours, with minimal tools
  • Space-saving—softwall cleanrooms tend to be compact and can fit nearly anywhere.  

These attributes make softwall cleanrooms great for temporary cleanrooms or cleanrooms requiring less stringent classifications, such as storage applications.
