Elastic bearing for
air handling andrefrigeration systems
Effective vibration isolation for entire unit

Keybenefits
Modern HVAC systems, air handling andrefrigeration units are usually installed inservice rooms in the basement, on mezzanine
floors or on the roof. This can lead tounwanted vibrations and noise inside thebuilding. This can be prevented with elasticbearings. The Isotop® product range has
proven particularly successful in this respect
and relies on the outstanding properties ofGetzner’s polyurethane materials Sylomer®,
Sylodyn® and Sylodamp®.

— Measurable reduction invibrations and secondary
airborne noise— Devices can be installed even indifficult locations (e.g. roofs andmezzanine floors)— Easy and convenient installation— Long service life and maintenance-freeApplication
Alongside fans and pumps, the compressors in the refrigerant circuit are the main source of unwanted vibrations. These are introduced into the HVAC unit asa result of the pressure pulsations of the compression
process. Furthermore, air currents and turbulences canalso cause the device to vibrate.
The vibrations are transmitted to the building structure via connection points, such as insufficiently elastic
mounting elements and lines, and are often perceived
as a deep ‘hum’ in adjacent living or working areas.
Elastic bearings are used to effectively isolate vibrations. The correct choice of bearings is crucial for agood result and prevents unnecessary alterations orretrofitting.

Product solutions
Elastic point and strip bearings made of Sylomer® havebecome a go-to solution. Metal-PUR combinations fromthe Isotop® range, such as Isotop® ENI, Isotop® SE orIsotop® SE-DE, make installation easier and offer greater
versatility.

Sylomer® point and strip bearings— Maintenance-free— Low deflection and long service life
— Highly effective at low overall height— Resistant to UV and hydrolysis— Free from plasticisers and environmentally
harmful substances

Isotop® ENI— Sylomer® or Sylodyn® inside— Integrated height adjustment— Ball-and-socket joint to compensate
for uneven floors and inclinations— Galvanised threaded bolt and polyamide
plastic plate for high corrosion resistanceFor trickier applications (hospitals, concert halls, theatres,etc.), the systems are mounted on Isotop® steel springisolators. Special elements such as the push-pull bearing
Isotop® DZE round off the product range.

Isotop® SE— Sylomer® inside – 1, 2 or 3-ply— 10 mm galvanised steel plate for pressure distribution— M12 internal thread for easy screwing— Also highly suitable for devices with narrow base frames— Optionally with foot plate or foot and pressure plate

Isotop® SE-DE— Sylomer® or Sylodyn® inside— 10 mm galvanised steel plate for pressure distribution— 60 mm-thick, heavy settling mass
— M12 internal thread for easy screwing— Category EL-3 according to DIN 8989 (VDI 2566)

Isotop® DSD and DSD-BL— High load capacity of up to 5850 kg per element— Sylodamp® inside – ideal for machineswith several start-stop cycles— CDC coating for springs and powder coating forpressure plates for outstanding corrosion protection— Secure connection between the plate and the spring
thanks to special bonding

Isotop® SD and SD-BL— High load capacity of up to 4730 kg per element— CDC coating for springs and powder coating forpressure plates for outstanding corrosion protection— Secure connection between the plate and the spring
thanks to special bonding— Top plate with M12 thread

Isotop® DZE— Resistant to compression and tension— Reduces high amplitudes— Designed for horizontal forces (e.g. high wind loads)— Sylodyn® and Sylodamp® inside— Stainless steel housing and continuous stainless steel piping
for ultimate corrosion protection— Rapid installation thanks to pre-assembled elements
