Vibration isolators for HVAC (heating, ventilation and air conditioning)
Vibration isolation for building services equipment (BSE)
Heating, ventilation and air conditioning (HVAC) systems are an indispensable aspect of modern building engineering. HVAC installations such as air-conditioning plants, air-conditioning systems, heat pumps or other building services equipment (BSE) provide the required comfort in residential and office buildings. They are also used in the industrial environment for cooling.
The vibrations caused by HVAC systems, especially when they are installed on a roof or inside a building, can have an adverse effect on the living and working environment in the adjacent parts of the building due to disruptive noise. This must be considered in BSE planning. Elastic bearings from Getzner provide the solution by reducing vibrations, structure-borne noise and secondary airborne noise and should be taken into account in the planning stage for building services equipment (BSE).
- Quieter HVAC equipment thanks to more efficient vibration isolation
- Reduced secondary airborne noise even in critical installation locations (e.g. rooftop installation, mezzanine floors, etc.) for building services equipment
- Installation and procurement are time and cost effective
- Reduced maintenance costs
- Also ideal for use outdoors
Our vibration isolation products for HVAC applications:
Heat pumps develop vibrations and structure-borne noise, primarily due to the compressors used. A suitable elastic bearing eliminates disruptive humming noises.
Modern air handling units (AC) or air conditioning units are usually installed on mezzanine floors or on the roof. With an elastic bearing, vibrations generated by the fan or air flows themselves cannot be heard in adjacent rooms.
Chillers and refrigeration systems are usually installed on the roof. An elastic bearing prevents strong vibrations generated by the fans and/or compressors used from being transmitted into the building structure.
Compressors are found as components in various systems, such as heat pumps or air conditioning units. Vibrations generated by the refrigerant compression process are decoupled by an elastic bearing, leading to quieter equipment.
In addition to the emergency power supply, e.g. in hospitals, power generators with combustion engines are also used as cogeneration plants for simultaneous heat recovery. These generate high levels of structure-borne noise and strong vibrations due to their large, moving masses and accelerations. Propagation of this noise and vibration is prevented by an elastic bearing.
Fans generate noise and vibrations due to rapid rotations, imbalances of the impeller or the drive motor. The use of an elastic bearing can prevent the propagation of this noise and vibration.
During lift system operation, the starting, stopping and general movement of the cabin generate vibrations. With an elastic bearing, these are not transmitted to the structure of the building or perceived as structure-borne noise.
Pipes in building services equipment leading from or to energy sources (AC, CHP, etc.) generate structure-borne noise and must be considered as a whole when decoupling the system from structure-borne noise.
Pumps usually convey liquid media with different viscosities. Depending on the medium, pressure and conveying distance, extensive structure-borne noise insulation must be considered.
Structure-borne noise is transmitted from the transformer core via the contact surfaces (e.g. the rollers) into the foundation. An elastic bearing is therefore required in order for the operation of transformers within buildings or in the immediate vicinity of buildings to not be perceived as unpleasant and disturbing in residential areas and workplaces.

Combined heat and power plants (CHP plants)
In addition to the emergency power supply, e.g. in hospitals, power generators with combustion engines are also used as cogeneration plants for simultaneous heat recovery. These generate high levels of structure-borne noise and strong vibrations due to their large, moving masses and accelerations.

Further advantages for HVAC equipment
Bearing of components inside HVAC equipment
Our Isotop® products for vibration isolation effectively reduce both structure-borne noise and secondary airborne noise. As elastic bearings inside machines and equipment, they isolate primary sound sources such as compressors or fans. This means that adjacent equipment components are not excited, and the equipment as a whole becomes noticeably quieter - an aspect that can already be considered when developing systems for building equipment.
HVAC systems installed on roofs
On buildings with building service installations on the roof, the use of elastic bearings in combination with damping materials is recommended. The damping effect is particularly relevant in the event of strong gusts of wind, for example, to prevent unwanted excitation of the installed equipment. The additional stability also helps to prevent a build-up of vibrations in the machine. This must be taken into account in BSE planning. The Isotop® products also act as vibration dampers here and prevent vibrations from becoming problematic, such as in the case of noise and vibrating surfaces in adjacent residential or commercial spaces. This is an aspect that should be considered by professional planners for building services equipment, for example when designing air conditioning and ventilation systems.
Unique properties of Isotop® products for building equipment
Bearings in the Isotop® range are specially designed for use with HVAC applications in building services equipment. However, they are also used in machine engineering in general. The advantage of these lies in the fact that the elastic properties of the Isotop® bearings can be calculated precisely. This means that optimum vibration damping is determined for each individual application in building services equipment. They also boast a consistently
reliable level of vibration isolation spanning decades. PU materials are free from softeners and exhibit no tendency towards temperature-related stiffening.
Isotop® products replace conventional rubber pads and are also used as anti-vibration mounts if required.
