Sub-Floor Void Cleaning & Plenum Extraction
Optimising Airflow and Eliminating Hidden Contaminants in the Critical Zone
The void beneath your raised access floor—the plenum chamber—is the lungs of your data centre. It is the primary delivery route for cold air to your server racks. Over time, this concealed space accumulates construction debris, abrasive concrete dust, and ferrous metal particulates. Left unchecked, this subfloor contamination creates three critical risks:
-
Airflow Obstruction: Dust dams block cold air supply, forcing CRAC units to work harder and increasing your PUE (Power Usage Effectiveness).
-
Equipment Damage: High-velocity air drags microscopic particles up into the server intakes, clogging heat sinks and causing hardware failure.
-
Fire & Static Risk: Loose debris rubbing against cabling can generate static charges or act as fuel for electrical fires.
The IsoGuard Process: We perform a forensic-level underfloor extraction without disrupting your live operations.
-
HEPA Filtration: We utilise industrial Class H HEPA vacuums (99.995% efficiency) to capture particulate matter down to 0.3 microns, ensuring dust is removed, not redistributed.
-
Zone-by-Zone Lifting: Our technicians lift floor tiles in a controlled checkerboard pattern to maintain floor integrity and static pressure.
-
Cable Integrity Check: While cleaning the slab surface, we simultaneously visually inspect underfloor cabling for damage or deterioration.
The Result: A sterile, unobstructed plenum that meets ISO 14644-1 Class 8 standards for void cleanliness. By restoring the design intent of your cooling system, you prolong hardware life and reduce cooling energy costs.
Technical Surface Cleaning & Anti-Static Floor Maintenance
Restoring the visual standard and electrostatic performance of your data hall
Visible dust on your raised access floor is more than just an aesthetic issue; it is an immediate threat to hardware reliability. Foot traffic grinds surface debris into fine airborne particulates, which are then drawn into server intakes by the high-velocity airflow of cooling systems. Additionally, dirty flooring acts as an insulator. This compromises the ESD (Electrostatic Discharge) properties of your High-Pressure Laminate (HPL) or Vinyl tiles, increasing the risk of static build-up that can fry sensitive logic boards.
-
Audit Readiness: External auditors and potential clients judge the health of your facility by its cleanliness.
-
Static Safety: A dirty floor cannot effectively dissipate static charge to ground.
The IsoGuard Process: We move beyond standard janitorial mopping, which uses incorrect chemicals and excessive water—two things that damage data centres.
-
HEPA Vacuuming: We begin with a complete HEPA extraction of the floor surface to remove loose abrasive grit before any friction cleaning occurs.
-
Low-Moisture Anti-Static Clean: We utilise specialized anti-static cleaning agents designed specifically for technical environments. These restore the dissipative qualities of the floor without leaving a sticky residue or introducing humidity risks.
-
Equipment Detailing: Using lint-free microfibre and entrapment techniques, we hand-wipe server rack exteriors, cabinets, and cold-aisle containment systems to remove settled dust.
The Result: A pristine, audit-ready data hall that looks professional and functions safely. Your floor's static-control properties are verified, and the risk of secondary airborne contamination is mitigated.
Server Intake & Bezel Decontamination (Vacuum Only)
Restoring airflow to active hardware without physical contact risks
The front intake grilles and perforated doors of your server racks are the first line of defence against dust. Over time, they act as a "fur trap," accumulating a grey mat of fibres and debris. If left unchecked, this buildup restricts the volume of cold air reaching the CPU and GPU heat sinks. This causes fans to spin up to maximum RPM (increasing energy costs) and raises internal component temperatures, shortening the lifespan of the silicon.
-
The Risk: Standard cleaning methods (wiping) can push dust into the ports or introduce moisture to live electronics.
The IsoGuard Process: We strictly adhere to a "Touchless Vacuum" protocol for active IT equipment intakes.
-
HEPA Extraction: We use soft-bristle, non-conductive brush attachments connected to variable-suction HEPA units to gently lift dust from server bezels and switch ports.
-
No-Wipe Zone: We never use cloths or liquids on active port faces or intake meshes. This eliminates the risk of static discharge, moisture ingress, or snagging cables.
-
Perforation Clearing: We specifically target the perforated server cabinet doors (front and rear) to ensure 100% of the designed open area flows air freely.
The Result: Unrestricted airflow to your critical hardware, allowing fans to run quieter and servers to run cooler, all achieved with zero physical risk to the equipment.
Visual Infrastructure Integrity Audit
Proactive identification of facility risks beyond cleanliness
Your cleaning team sees more of the physical facility than anyone else. While we are cleaning every square metre of sub-floor and ceiling, we often spot developing issues that remote monitoring software misses. A cracked tile, a weeping pipe, or a gnawed cable can turn into a disaster if ignored. IsoGuard cleaning teams consider it part of our duty of care to report what we find.
The IsoGuard Process: During every PRO, PRO+, or MAX visit, our technicians conduct a simultaneous visual inspection of the physical environment.
-
Sub-Floor Inspection: We check for signs of moisture/water ingress, rust on pedestal legs, or concrete screed deterioration (dusting).
-
Cable Management Check: We identify "rats nests" of cabling blocking airflow, unsealed cable penetrations (loss of plenum pressure), or damaged outer sheathing.
-
Physical Security: We note damaged floor tiles, rocking tiles, or gaps in the containment barriers that could cause trip hazards or air leakage.
The Result: A detailed section in your Service Report highlighting any physical defects found, complete with photos. This acts as an "Early Warning System" for Facilities Managers, allowing them to fix minor issues before they become expensive outages.
Zinc Whisker Identification & Mitigation
Managing the invisible, conductive threat to mission-critical hardware
Zinc Whiskers are the most dangerous contaminant in older data centres (typically 10+ years old). They are microscopic, conductive metal filaments that grow on the underside of electroplated steel floor tiles. Because they are fragile, standard cleaning or reckless tile lifting breaks them free. Once airborne, they enter server power supplies and logic boards, causing catastrophic short circuits and unexplained hardware failures.
-
The Trap: You cannot see them with the naked eye.
-
The Risk: Standard cleaners often worsen the issue by scrubbing aggressive surfaces, launching millions of conductive particles into the airflow.
The IsoGuard Process: Reduce Zinc Whisker risk is a surgical procedure, not a cleaning job. We follow a strict containment protocol to safely remove the threat without contaminating the live environment.
-
Microscopy Analysis: We begin with a forensic audit, using on-site microscopy to confirm the presence and density of zinc filaments on your tile substructure.
-
Gentle Extraction: We use specialized soft-touch HEPA extraction techniques on the underside of tiles and stringers. We avoid stiff brushes or high-abrasion tools that would shear the whiskers into the air stream.
-
Bag-and-Seal Removal: If infestation is severe, we manage the safe removal and replacement of affected tiles by sealing them before they leave the controlled zone.
The Result: The immediate reduction of electrical short-circuit risks. We provide a Service Report confirming the reduction of metallic particulate levels, giving you peace of mind that your legacy infrastructure is not killing your new servers.
Thermal Imaging & Airflow Efficiency Audit
Identifying invisible hotspots and bypass airflow to optimize cooling
Temperature sensors on the wall don't tell the whole story. A server room can have a perfect average temperature while hiding critical "Hot Spots" inside specific cabinets where airflow is blocked. These localized pockets of heat force server fans to run at max speed, risking hardware burnout. Conversely, "Cold Spots" (over-cooling) indicate wasted energy and bypass airflow, where expensive cold air is leaking out of the floor before it ever reaches a server.
-
The Risk: Hot spots are the leading cause of unexplained individual server failures.
-
The Cost: Bypass airflow forces CRAC units to work 20-30% harder than necessary.
The IsoGuard Process: We utilize industrial-grade FLIR (Forward Looking Infrared) thermal cameras to visualize the temperature dynamics of your data hall.
-
Aisle Scanning: We scan cold aisles for uneven air distribution and identify "short cycling" (where hot air recirculates back into the intake).
-
Rack-Level Inspection: We identify specific cabinets or U-spaces that are running hotter than their neighbors—often a sign of internal cable blockages or dust-clogged intakes.
-
Floor Leak Detection: We spot gaps in the raised floor (unsealed grommets) where cold air is escaping unnecessarily.
The Result: A visual Heat Map Report included in your service pack. We pinpoint exactly where you are wasting energy and where your hardware is at risk, allowing your facilities team to install blanking panels or adjust floor grilles to fix the problem immediately.
Air Quality Validation & ISO 14644-1 Certification
Scientific verification of your data centre’s cleanliness standards
You cannot manage what you do not measure. In a critical environment, visual cleanliness is not enough—microscopic particles invisible to the naked eye (0.5µm - 5.0µm) can still cause catastrophic head crashes in disk drives and clog micro-circuitry. Furthermore, stakeholders, insurance providers, and hardware warranties (such as Cisco or Dell EMC) often mandate adherence to ISO 14644-1 Class 8 standards. Without a validated certificate, you may be liable for hardware failures or breach of SLA.
The IsoGuard Process: We do not just clean; we validate. Using calibrated industry-standard laser particle counters, we conduct a forensic assessment of your data hall's air quality.
-
Laser Particle Counting: We sample airborne particulate levels at specific grid points across your facility to measure concentration per cubic metre.
-
ISO Class 8 Benchmarking: We test against the global standard for operational data centres (maximum 3,520,000 particles at 0.5µm per m³).
-
ATP Surface Testing: We verify biological hygiene on high-touch surfaces (door handles, keyboards) using Adenosine Triphosphate (ATP) swabs to ensure biosecurity.
The Result: A comprehensive Digital Validation and Compliance Report provides proof to auditors and clients that your facility meets the highest global standards for air cleanliness.
CRAC Unit Intake Filtration & Maintenance
Reducing PUE and protecting cooling infrastructure from particulate clogging
Your Computer Room Air Conditioning (CRAC) units are crucial to your data centre, constantly filtering the air. However, a blocked intake filter is a silent energy killer. As dust loads increase on the filter media, static pressure drops. This forces the variable speed fans to work harder to push the same volume of air, significantly increasing your Power Usage Effectiveness (PUE) ratio. Worse, if filters are bypassed or damaged, contaminants hit the cooling coils directly, leading to evaporator freezing or catastrophic compressor failure.
The IsoGuard Process: We provide a managed filter replacement service that ensures zero-bypass filtration.
-
Safe-Bag Removal: The most dangerous moment is removing the dirty filter. We use a "bag-and-seal" technique to ensure the captured dust cake is not shaken loose back into the room during removal.
-
G4/F7 Media Installation: We supply and install high-grade synthetic media (G4 to F7 standards) cut to the exact dimensions of your intake plenum to prevent "air leakage" around the edges.
-
Plenum Wipe-Down: Before the new filter goes in, we vacuum and wipe the filter housing and intake grilles to remove established debris.
The Result: Restored airflow dynamics and reduced fan energy consumption. Your cooling units run more efficiently, and the air returning to your servers is verified clean.
IsoGuard Sentry: Real-Time Air Quality Monitoring
Continuous 24/7 environmental intelligence for mission-critical facilities
Traditional cleaning and validation happen quarterly. But what happens in the 89 days between our visits? A contractor drilling a wall, a door left propped open, or a degraded belt can spike contamination levels overnight. Without real-time data, you are flying blind until the next audit. ISO 14644-1 compliance should be a continuous state, not just a one-day certificate.
The IsoGuard Process: The IsoGuard Sentry™ is an industrial IoT laser particle counter that sits permanently in your server room.
-
Laser Precision: It continuously samples the air, counting particles at 0.5µm, 2.5µm, and 5.0µm sizes (the ISO standard thresholds).
-
Live Dashboard: Data is streamed securely to a cloud dashboard, giving you a live "Health Score" of your facility's air quality.
-
Smart Alerts: If particulate levels breach ISO Class 8 limits (e.g., due to a spill or maintenance work), the system instantly alerts your team and ours via SMS/Email, triggering an optional Emergency Response visit.
The Result: Total assurance. You stop guessing and start knowing. You can prove to clients and auditors that your facility remained compliant every single hour of the year, not just on cleaning day.
Overhead Cable Tray & Ceiling Void Decontamination
Eliminating the risk of "Dust Rain" from suspended infrastructure
While most cleaning focuses on the floor, the most dangerous contaminants are often above your head. Overhead cable trays, fibre runners, and suspended ceiling grids act as static dust magnets. Over time, these "dust bunnies" accumulate into heavy clusters. A simple vibration—from a door slamming, maintenance work, or high-velocity air conditioning—can dislodge this debris. This causes a "Dust Rain" event, where contaminants fall directly into the top-mounted cooling intakes of your server racks, bypassing floor-level filtration entirely.
-
Fire Risk: Accumulated dust on lighting fixtures and power cables is a known combustion hazard.
-
Cooling Blockage: Falling debris is the most common cause of sudden intake clogging.
The IsoGuard Process: Cleaning above live servers requires extreme precision. We utilise specialised access equipment and containment protocols to ensure no debris falls during the cleaning process.
-
HEPA Capture: We use backpack-mounted HEPA vacuums with non-conductive wands to gently extract dust from cable bundles and trays.
-
Microfibre Capture: For delicate fibre-optic runners, we use magnetic-static microfibre cloths that trap dust on contact rather than sweeping it into the air.
-
Infrastructure wiping: We clean suspended ceiling tiles, lighting troffers, and smoke detectors to ensure the entire vertical volume of the room is sterile.
-
This service is conducted on an ad hoc basis and quoted seperately.
The Result: The elimination of gravity-fed contamination risks. You can perform maintenance on cables or change ceiling tiles without fear of triggering a contamination event that compromises your active equipment.
