Plant rooms and rooftops
Plant rooms, rooftops, floating floors and slabs, theatres, nightlife and gyms: vibration and noise never reach the people inside or the neighbours.
Air-conditioned building
From the roof to the rooms: how vibration travels
Switch on the HVAC
Start the equipment and switch to night mode: without mounts, the vibration wakes whoever sleeps below.

Illustrative simulation, not a measurement.
1Rooftop chiller
The problem
Several tonnes of compressors and fans running on the top floor slab: the vibration goes straight down to the rooms below.
What we fit
Double springs with restraint under the chiller: they isolate at low frequency and hold it against wind and earthquakes.
Restrained spring isolators · 3.5 Hz
Typical choice
Proven in HVAC: Schneider Electric, Japan (2022): seismic protection of chillers in seismic zone IV with seismically restrained spring isolators, 3.5 Hz natural frequency and seismic displacement under 15 mm.
The final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.
2Cooling tower
The problem
The tower fan never stops, with water falling: continuous vibration and imbalance.
What we fit
Double springs with restraint, working in compression and withstanding the weather.
Typical choice
The final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.
3Air handling unit (AHU)
The problem
The fans of the air handling unit pass vibration to the slab and noise to the ducts.
What we fit
Spring isolators under the unit and isolators on the ducts.
Typical choice
The final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.
4Circulation pumps
The problem
The basement pumps move the water for the whole building and pass their vibration to the foundation and the pipework.
What we fit
Double springs with restraint under each pump, or a floating slab for the whole pump room.
Typical choice
The final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.
5Pipework and ducts
The problem
Pipes and ducts, hung from the slabs, carry the equipment's vibration through the whole building.
What we fit
Anti-vibration pipe hangers and isolators for suspended ceilings and ducts.
Typical choice
The final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.
6Rooms and offices
The problem
This is where it all shows: a background hum at night, vibration in the floor or the bed. And it is what hotel guests and office tenants complain about.
What we fit
Vibration is cut at the source, under each unit, and along the way, in pipes and ducts. So it never reaches the rooms.
Typical choice
The final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.
