Start from a measured zero.
The 0-beurt is a one-off, intensive baseline clean that brings a space up to ISO 14644-1 Class 8, the measured starting point your periodic cleaning then maintains.
Why it’s called the zero
Before you can maintain a standard, you first have to reach it. The 0-beurt strips out the accumulated dust, debris and construction residue a space carries, and establishes a clean, documented baseline (the ‘zero’) against which every later clean is measured.
When you need a 0-beurt
After construction
New and just-delivered facilities are full of fine building dust that regular cleaning never reaches.
After renovation or works
Any work in or near the room, such as cabling, HVAC or electrical, pushes particles back into the air.
Taking over a space
Inheriting a neglected or undocumented room? Start clean, with a measured baseline you can prove.
Before a maintenance contract
We set the baseline first, so periodic cleaning has a clear standard to hold it to.
After an incident
Smoke, a dust event or contamination calls for an intensive reset back to standard.
Ahead of an audit
Get demonstrably within Class 8 before an inspection or certification audit.
Measured, not assumed
From contaminated to Class 8
When needed, a 0-beurt can open and close with a particle measurement, so the result is measured rather than assumed.
What a 0-beurt covers
Top to bottom, including the places dust hides.
- Raised floor, top and underside
- Subfloor plenum & cable trays
- Server racks & cabinet exteriors
- CRAC/CRAH units & air paths
- Ceiling void & overhead infrastructure
- Walls, surfaces & entry zones
- Cabling, containment & trunking
- Particle measurement (when needed)
What is always included
The same controlled standards on every engagement.
HEPA 14 filtration
Dust-free extraction with HEPA 14. Particles leave the room instead of being stirred back into the air.
ESD-safe working
Antistatic materials and ESD-trained staff protect sensitive electronics.
No disruption
We work around your operation, live and with no downtime.
Certified & screened team
VCA VOL, NEN 3140 and ESD-trained, plus security-screened for sensitive sites.
