What is the Difference Between a Controlled Environment and a Cleanroom?

What is the Difference Between a Controlled Environment and a Cleanroom?

by | Apr 15, 2024 | Cleanrooms, Helpful Tips

The words cleanroom and controlled environment are often used interchangeably when talking about environment control in critical spaces. But what is a cleanroom? What is a controlled environment? There is a difference, and that difference is crucial. When it comes to controlled environments vs. cleanrooms, here’s what you need to know:

Controlled Environments vs. Cleanrooms

What Is a Controlled Environment?

A controlled environment, or critical environment, is an area that must have specific parameters controlled. The parameters include pressure, temperature, and segregation. Many laboratories are considered controlled environments, as they have controlled temperature and pressure and are separated from other operations, such as manufacturing or shipping. Unlike cleanrooms, controlled environments do not necessarily have to meet certain standards for particle contamination.

Common Applications for Controlled Environments:

  • Life science laboratories
  • Engineering laboratories
  • Laser labs
  • High-energy physics facilities
  • Hospitals
  • Cannabis grow rooms
  • Clean manufacturing
  • Food processing rooms
  • Pharmacies
  • Quality labs

What Is a Cleanroom?

A cleanroom is a type of controlled environment with much more stringent requirements. Cleanrooms require temperature and pressure control, as well as separation from the outside environment and other operations. 

All the requirements of cleanrooms are regulated and must meet designated standards. Cleanrooms are classified by the maximum acceptable number of particles (by size) in the air per cubic meter, and must be regularly tested to ensure compliance with that standard (see more about cleanroom classifications here). Compared to standard controlled environments, cleanrooms may require more energy, air, and advanced technology to maintain the cleanroom conditions.

Common Applications for Cleanrooms:

  • Semiconductor manufacturing
  • Pharmaceutical manufacturing
  • Research and development 
  • Laser and optics 
  • Electronics manufacturing 
  • Medical device manufacturing 
  • Precision industrial manufacturing 
  • Aerospace 
  • Mask manufacturing
  • 3D printing 
  • Nutraceutical cleanroom
  • Food processing/bottling

Do I Need a Cleanroom or a Controlled Environment? 

The answer to this question depends on two factors: your application and your industry. If packaging medical devices, you’ll need an ISO class 7 compliant cleanroom or higher. If you have a process control laboratory for a chrome plating company, you aren’t required to meet a specific ISO classification, but you need to control the environment. 

You may even have different needs within your facility; you may need a controlled environment for sensitive materials that don’t need to meet cleanroom standards but also require an ISO class 8 cleanroom for quality control testing.

When building and designing a cleanroom, contractors consider various factors to determine the necessary construction materials and regulating equipment. To ensure the facility is accurately equipped and meets standards, the contractor will consider the following: 

  • Required ISO class FDA regulations
  • Types and placement of HEPA or ULPA filters
  • Environmental conditions 
  • HVAC requirements
  • Spatial specifications
  • Construction materials
  • Air showers
  • Pass-thru units
  • Fire protection
  • Light and air supply
  • Electrical and plumbing requirements
  • Equipment hookups and special equipment

How Can I Control Cleanroom Humidity?

How Can I Control Cleanroom Humidity?

by | Mar 13, 2024 | Air Circulation, Cleanrooms

Maintaining optimal humidity levels in your cleanroom is paramount to meeting regulatory standards and safeguarding the quality of your processes and products. 

In this blog, we’ll explore the importance of cleanroom humidity control and provide insights and strategies to ensure your cleanroom operates at peak efficiency.

Understanding Cleanroom Humidity

Cleanroom humidity plays a crucial role in various industries, from semiconductor manufacturing to pharmaceutical production. If the humidity is too high, bacterial growth can flourish, metal products or equipment can corrode, photolithographic degradation can occur, and condensation and water absorption can occur. This can cause issues for processes with moisture-sensitive products, like semiconductor manufacturers.

If the humidity is too low, static buildup and discharge can become an issue, possibly causing shorts for products in electronics cleanrooms. Plus, poorly controlled humidity can make working conditions uncomfortable for your employees. Therefore, it’s essential to strike the right balance to mitigate these risks effectively.

What Factors Impact Cleanroom Humidity?

Various factors influence cleanroom humidity levels, each critical in achieving optimal conditions.

Factors impacting cleanroom humidity include:

  • Temperature: Lower temperatures reduce relative humidity, while higher temperatures can increase it. Maintaining precise temperature control is vital for regulating humidity levels.
  • Airflow: Proper airflow distribution helps to prevent moisture buildup and ensures uniform humidity throughout the cleanroom.
  • External Environmental Conditions: Factors such as outdoor humidity, weather changes, and nearby sources of moisture can impact cleanroom humidity levels. Monitoring and adjusting for these external conditions are necessary for consistent humidity control.

3 Methods for Controlling Cleanroom Humidity Levels

So, what are some of the methods you can use to control humidity in your cleanroom? The experts at Angstrom Technology are here to answer that question.

1. Air Conditioning and Mechanical Refrigeration

Humidity is relative, meaning that the lower the temperature is, the lower the relative humidity is. So it only makes sense then that lowering a cleanroom’s temperature will decrease humidity. 

When using air conditioning systems to dehumidify a space, the system reduces the temperature of a surface within the condenser unit to a temperature below the dew point of the airstream in the cleanroom. That surface is then exposed to the airstream in the cleanroom and the water vapor in the airstream condenses, subsequently dehumidifying the space. The air must be re-heated to the desired room temperature and piped back into the cleanroom.

2. Desiccants

Desiccant systems draw air through a desiccant medium, which absorbs moisture. The dehumidified air is then routed to the cleanroom. Consumer-grade desiccant systems collect condensate in a receptacle that must be emptied. 

On the other hand, commercial systems exhaust humid air through the ductwork out of the building. Vented systems can dehumidify to lower relative humidity levels at lower temperatures.

These systems are not mutually exclusive. In fact, where temperature control is also important, they work best when used in conjunction. Using a desiccant system in addition to air conditioning can also help reduce the load on the HVAC system, saving energy, wear and tear on the HVAC system, and, of course, money.

3. An Integrated Approach

An integrated approach to humidity control combines air conditioning with desiccant systems to comprehensively regulate temperature and moisture levels within the cleanroom environment. By integrating these systems, businesses can effectively address both temperature and humidity concerns, ensuring optimal conditions for processes and product integrity. 

This approach not only enhances energy efficiency by optimizing the utilization of both systems but also extends the lifespan of the HVAC system by reducing its workload and minimizing wear and tear on components. Consequently, businesses can benefit from lower maintenance costs and prolonged equipment longevity. 

Moreover, the integrated approach optimizes cleanroom performance by maintaining precise and consistent control of humidity levels, safeguarding sensitive processes and products. This strategy offers operational flexibility by providing redundancy in humidity control mechanisms, minimizing downtime and disruptions in cleanroom operations.

What’s the Difference Between Horizontal vs. Vertical Laminar Flow Hoods?

What’s the Difference Between Horizontal vs. Vertical Laminar Flow Hoods?

by | Feb 12, 2024 | Filtration

Laminar flow hoods play a crucial role in minimizing contamination for sensitive products. In this blog, we’ll compare horizontal vs. vertical laminar flow hoods, providing insights into their configurations, pros, and cons. 

Whether you’re working with IV solutions, tissue culture, optics, or microelectronics, understanding these flow hoods is key to a contaminant-free workspace. Join us as we navigate the differences to help you make informed decisions for your cleanroom requirements.

Understanding Laminar Airflow and Its Crucial Role in Cleanrooms

Laminar airflow is air that constantly moves at the same speed in the same direction. In cleanrooms, a vertical laminar flow room is an enclosure where 100% of the ceiling provides filtered air downwards from the ceiling. Because of the 100% filter coverage, it creates an ultra-clean environment. But it’s much easier to achieve laminar flow in a smaller space, as equipment, personnel, and movement in a room cause turbulence that disturbs airflow.

A laminar flow hood is a device or enclosure commonly used as an ultra-clean workbench in laboratory applications. Filtered air sweeps particles in a uniform speed and direction from the hood’s most treated area (the filter) to its exit area.

Cleanroom airflow uniformity and laminar flow hoods are essential to ensuring that sensitive products placed under the hood are always upstream and, therefore, suffer little to no contamination. 

Horizontal vs. Vertical Laminar Flow Hoods

Flow hoods come in two configurations: horizontal and vertical. Both designs provide an effective sweeping action through the work zone and meet ISO Class 5 cleanliness standards. Your application and needs will help determine which is better for your facility.

laminar flow hood

Horizontal Laminar Flow Hoods

As their name indicates, horizontal laminar flow hoods direct air horizontally. Air is pushed through a HEPA or ULPA filter positioned on the back wall and moves forward across the work surface until it exits the enclosure.

By sweeping the air across the work surface and towards the operator, horizontal laminar flow hoods provide the highest protection from contaminating particles. No turbulence is caused by vertical air striking a perpendicular surface or the hands of the operator since they’re always further downstream than the materials they are working on.

However, the hood’s size, the filter’s positioning, and the airflow’s direction can also result in some negative consequences. Below you’ll find a helpful list of pros and cons for these types of hoods:

Pros

  • Low turbulence on the work surface due to air flowing parallel to the work surface
  • Easy to position products and materials close to the filter on the work surface
  • Little contamination from hands or gloves due to the operator being downstream from products and materials

Cons

  • Requires hood repositioning to gain rear access for filter changes and servicing
  • Objects can obstruct the flow and contaminate anything downstream
  • Operators could suffer from fume or powder contaminants blowing at them if they don’t use the sash correctly

Vertical Laminar Flow Hoods

In contrast, vertical laminar flow hoods take air from above the unit, push it through the HEPA or ULPA filter, and then direct it down onto the work surface, where it eventually disperses and exits the enclosure out of a front access area. They resemble the model of a laminar flow cleanroom with fan filter units on the ceiling, just on a much smaller scale.

Vertical laminar flow hoods are popular because of their size, layout, and operator safety. Since the filter is at the top of the unit rather than behind, these flow hoods require less floor space but can be taller to fit larger products and materials. Also, since the laminar air isn’t blowing toward the operator, they are less likely to suffer any contaminants.

Vertical laminar flow hoods are an excellent choice for many applications, including handling sterile, non-hazardous drug compounding in research labs, pharmacies, and microbiology. Here’s a quick overview of their pros and cons:

Pros

  • Require less floor space
  • Increased operator safety
  • Easy access to filter changes and servicing
  • Less cross-contamination of items on the work surface due to no parallel airflow
  • A taller system that can accommodate tall and large products and materials

Cons

  • May require overhead clearance for changing and servicing the filter
  • Increased work surface turbulence due to vertical air hitting a perpendicular surface
  • Products and materials could obstruct airflow when stacked

Which Laminar Flow Hood Is Right for Your Application?

Both horizontal and vertical laminar flow hoods can be utilized for many applications involving sensitive products and materials, including (but not limited to):

  • Injectable drugs
  • IV solutions
  • Tissue culture
  • Optics
  • Microelectronics

While both types of flow hoods are optimal for reducing contamination in a workspace, a few applications lend themselves more toward one or the other. Usually, the most important factors to consider include process location, clearance requirements, size of materials, work surface design, and operator safety.

That said, horizontal laminar flow hoods generally work best for applications that require minimal turbulence on the work surface and the highest level of object contamination control. If your application’s process is performed above the work surface, a vertical airflow configuration may be ideal; particles inside a vertical unit settle at the bottom of the work surface before exiting the enclosure. Vertical hoods are also a popular choice for any applications involving materials that could be especially large or dangerous to the operator.
