Vibration Isolators Spring Based WEICCO supplies a complete range of spring based isolators designed to minimize structural transmission of noise and vibration generated by mechanical systems Typical applications include HVAC equipment eg chillers pumps fans AHUs cooling towers HVAC piping and ducting Riser piping installations DG
structure borne sound problems created by HVAC equipment where vibration isolators have been used This problem may be due to the fact that the effect of floor mobility is ignored in selection of the vibration isolators In this paper the effect of floor mobility on the isolation efficiency of vibration isolators
Use neoprene vibration isolators under compressors air conditioning equipment pumps machine tools transformers and more Spring floor mount vibration isolators feature steel springs that help reduce vibration transmissions as performance improves with larger deflections G ratings meet horizontal requirement of most seismic zones
The spring isolators for HVAC are used to suspend the air conditioning equipment and ducting etc from the ceiling or the support structure The spring isolators HVAC work on the same principle as any other spring vibration isolator and can provide the desired spring deflection

A Series Spring Flex Isolators with an elastomeric cup are designed to isolate low frequency vibrations in air handling units fans chillers and other HVAC equipment The A Series are recommended for use directly under HVAC power generation and electrical equipment in conjunction with structural steel bases and concrete inertia blocks
Spring Vibration Isolators are very effective product that is used to isolate cooling towers chillers various HVAC equipment and other machinery Steel Spring provides perfect vibration damping for the application where low frequencies are present
The use of vibration isolators simply isolators from this point forward in order to isolate mechanical equipment is a typical solution that engineers or acousticians always recommend In the large range of isolators neoprene and spring isolators are the most utilized the
reduced It is desirable to select isolators with a natural fre quency as far below the equipment operating speed as possi ble to achieve the highest degree of vibration control The Theoretical Isolation Efficiencyshown on the transmis sibility curve assumes the isolators are located on a rigid floor
Isolators are attached directly to equipment Direct isolation can be used if equipment is unitary and rigid without the use of additional support Direct isolation is not recommended for equipment having large overhung loads motors on arrangement 9 fans If there is any doubt that equipment can be supported directly on isolators
Many equipment isolation systems are required to be isoelastic That is the system translational spring rates in all directions are the same Many pieces of equipment are relatively light in weight and support structures are relatively rigid in comparison to the stiffness of the isolators used to support and protect the equipment
Hydraulically Adjusted Spring Isolators Many years ago we designed the SLRJ Mounting They have structural steel sides with removable spacers on top that support equipment rigidly during erection Because the equipment is held at elevation water electrical and other services can be completed without waiting for spring adjustment
Vibration in HVAC systems creates noise and can reduce the life of components and joints Properly sized isolators can reduce vibration as much as 99% and improve the sound quality of the system Typical isolators include Compression Mounts Spring Mounts and Stud/Plate Mounts Typical Uses Motors Blowers Fans Exhaust Compressors
2 Spring Isolators Type S Shall be free standing laterally stable and include acoustical friction pads and leveling bolts Isolators shall have a minimum ratio of spring diameter to operating spring height of and an additional travel to solid equal to 50 percent of rated deflection 3 Captive Spring Mount for Seismic Restraint Type
Spring Floor Mounted Non Seismic VMC Group offers an extensive range of spring isolators designed to dramatically limit the transmission of vibration impact and noise over a variety of commercial construction applications from gensets and small fans to heavy duty HVAC equipment
D Adjust equipment level E Install spring hangers without binding F On closed spring isolators adjust so side stabilizers are clear under normal operating conditions VIBRATION CONTROL AND SEISMIC RESTRAINT DEVICE INSTALLATION A Equipment Restraints 1 Install seismic snubbers on HVAC equipment mounted on vibration isolators Locate
Isotech s spring mount vibration isolators are designed to diminish these factors We offer a broad range of spring isolation mountings that will limit the transmission of vibration impact and noise over a variety of applications from engine generator sets and small fans to heavy duty HVAC equipment and industrial machinery
To Select The Proper Isolation For Mechanical Equipment in Most Applications You Need to Ask Is slowest equipment SPEED ABOVE 1200 rpm If NO use spring mountings If YES see 2 Vibration from equipment running at slow or variable speeds can pass through low deflection isolators and possibly be amplified by them
Others are spring isolators which are point loaded to support equipment and absorb vibration Engineers select the isolators according to the minimum operating speeds and weight of the equipment Generally equipment that runs more slowly — say cooling towers — requires larger softer spring isolators
Commonly used applications include but not limited to cooling towers chillers HVAC units generators pumps and other types of equipment Housed floor mounted spring isolators can have springs with up to 2 deflection Bottom housing incorporate elastomeric ribbed rubber pad to prevent the vibration going downwards from the structure
Piping supports cable raceway supports HVAC ducting supports equipment supports elastomer vibration isolators metal spring isolators and fixed bases outside containment /LOCA restraints frames and saddles/LOCA restraints frames and saddles/ring foundation for flat bottom vertical TKs
Vibration isolation technology has moved on to the isolation of entire buildings rather than just building components We have designed and manufactured Neoprene and Natural Rubber bearing pads to frequencies as low as 6 Hz and steel spring assemblies in the to inch 19 to 50mm deflection range in individual capacities of 1 000 000 lbs 454 000 kgs
