Critical Environments

What are Mission Critical Environments?
‘Mission’ Critical Environments refer to facilities where uninterrupted operation is crucial for the organization’s core functions. These include data centers, control rooms, and healthcare facilities, among others.
Why do they need to be cleaned?
Maintaining cleanliness in mission critical environments is essential to ensure optimal operational conditions. Contaminants such as dust, dirt, and debris can compromise equipment performance, airflow, and cooling efficiency. They can also pose risks to data integrity, equipment reliability, and even personnel health.
Why do they need specialized cleaning?
Specialized cleaning is necessary in these environments due to their unique operational requirements and sensitivity to contamination. Conventional cleaning methods may not suffice, as they might introduce particulates or residues that could disrupt sensitive equipment or compromise clean room standards. Specialized cleaning ensures that stringent cleanliness and safety standards are met without disrupting critical operations or compromising environmental integrity.
What are the typical elements of Critical Environment Solutions?

Overhead Cleaning
We meticulously clean critical components like cable trays, lighting fixtures, ductwork, and piping in clean room environments to remove dust and maintain optimal operational conditions across different ISO classifications.

Ceiling Plenum Cleaning
Regularly cleaning the ceiling plenum in clean rooms is essential for removing airborne particles, reducing filter strain, and safeguarding equipment performance, ensuring ISO cleanliness compliance. We also offer robotic cleaning for HVAC ducts upon request.

Exterior Hardware Cleaning
Using eco-friendly solutions and HEPA filtered vacuums, we clean hardware components such as server racks, switches, and routers in clean room facilities to enhance reliability and extend operational lifespan while meeting ISO standards.

Top of the Floor Cleaning
Our specialized agents remove dust and dirt from clean room flooring, ensuring proper static dissipation and safe operational conditions under various ISO classifications.

Underfloor Plenum Cleaning
We provide targeted cleaning of the underfloor plenum in clean room environments to prevent dirt buildup, minimizing risks to equipment and ensuring compliance with stringent ISO standards for clean room operations.
What Cleaning Standard do you require?
Clean rooms and other critical environments are classified based on their level of airborne contamination, as defined by the ISO 14644-1 standard. This standard has replaced the older US Federal Standard 209E and provides a comprehensive framework for measuring and reporting air cleanliness by counting particles of different sizes in a cubic meter of air. The higher the number of particles, the dirtier the room.
The table below outlines the different classes of clean rooms, the number of particles per cubic meter by micrometer size and typical uses for each class. This classification helps ensure that facilities meet the necessary cleanliness standards to protect sensitive equipment and processes.
Class | Particulate Count/m³ by Particle Size(µm) | Typical Use | |||
0.1 µm particles | 0.5 µm particles | 1 µm particles | 5 µm particles | ||
ISO 9 | NA | 35,200,000 | 8,320,000 | 293,000 | General Manufacturing, General Quality Control Laboratories, Consumer Electronics Production |

ISO 7 | NA | 352,000 | 83,200 | 2,930 | Hospital operating rooms, some factories |
ISO 6 | 1,000,000 | 35,200 | 8,320 | 293 | Manufacturing computer disk drives, sensitive materials |
ISO 5 | 100,000 | 3,520 | 832 | 29 | High-purity fine chemicals for industrial use and research, ion lithium batteries for electric vehicles, solar panel manufacturing, active medical devices |
ISO 4 | 10,000 | 352 | 83 | NA | LED Manufacturing, High-precision Machining, Satellite Assembly, Photolithography, High-purity Chemical Synthesis |
ISO 3 | 1,000 | 35 | 8 | NA | Optical Fiber Production, Laser Assembly, Aerospace Component Manufacturing, Medical Implants, Production of storage devices like SSDs. |
ISO 2 | 100 | 4 | NA | NA | Microelectronics Fabrication, Production of highly sensitive medical implants, Manufacturing of sterile pharmaceutical products with high sensitivity, Advanced Biotechnology Research, Precision Metrology |
ISO 1 | 10 | NA | NA | NA | Advanced Semiconductor Manufacturing, Aerospace Instrument Assembly, Ultra-precision Optics. Nanotechnology Fabrication, Genetic Research |
