This acknowledgement positions Embelton as one of the most enduring and widely recognised suppliers of vibration, acoustic and seismic isolation systems in the Australian HVAC-R industry.

HVAC Mechanical Isolation – Protecting Buildings & Occupants from Noise & Vibration

HVAC Mechanical Isolation Overview:
https://embeltonengineering.com/pages/hvac-mechanical-isolation

Embelton provides engineered solutions to isolate:

• Air Handling Units (AHUs)
• Fan Coil Units (FCUs)
• Chilled-water & condenser-water pumps
• Refrigeration compressors & condensing units
• Cooling towers & fluid coolers
• Exhaust/supply fans
• Rooftop plant platforms

These systems help:

• Meet acoustic consultant targets
• Prevent occupant noise complaints
• Reduce structural resonance
• Improve plant longevity
• Ensure compliance under NCC, project specifications and acoustic design guidelines

• Equipment Isolation – Rubber, Spring & Seismic Solutions

Equipment Isolation Systems:

Embelton manufactures a comprehensive range of engineered isolation hardware for mechanical services:

Rubber Mounts

• Ideal for FCUs, small fans and light compressors
• Fast to install and cost-effective
• Suitable for commercial tenancy-level plan

Spring Mounts

• Designed for pumps, AHUs, cooling towers and heavy rotating equipment
• Offer up to 98–99% reduction in transmitted vibration (dependent on deflection selection)
• Preferred for hospitals, high-rise commercial and sensitive environments

Vibration Isolation Hangers

• For ductwork, pipework and riser services
• Often required in health, laboratory and mixed-use developments
• Minimise vibration transmission through vertical structures

Seismic Mounts (Combined Isolation + Restraint)

• For seismic regions or critical infrastructure
• Meet Australian Standards for restraint and displacement
• Required for defence, health, data centre and essential-services buildings

Building Isolation – For Highly Sensitive Environments

Building Isolation Systems:

Used where vibration control must be absolute, including:

• Plantrooms above operating theatres
• Vibration-sensitive laboratory spaces
• Museums, archives & fine-art repositories
• Recording studios & performance venues
• Precision manufacturing environments

These systems allow mechanical engineers to HVAC systems without transmitting disruptive vibration into sensitive zones.
