Custom solutions for industrial noise control.
Hela Innovations supplies industrial acoustic silencers, acoustic enclosures and perforated sheet products for air, gas and exhaust duties. Every unit is engineered to your process conditions, installation and site noise limit, and is delivered together with our engineering and manufacturing partner in India.
A broad offer across industrial air, gas and exhaust duties
Each enquiry defines the scope of supply, design responsibility and operating limits. Specialist duties are handled with a dedicated technical review.
| Product family | Available configurations | Typical duty |
|---|---|---|
| Vent and blow-off | Steam, air and process gas vents | Atmospheric release |
| Compressor | Suction, discharge and inline | Air and gas systems |
| Fan and blower | Inlet, outlet and duct silencers | Industrial airflow |
| Gas turbine | Intake and exhaust silencers | Turbine packages |
| Engine exhaust | Diesel and gas engine silencers | Exhaust systems |
| Acoustic enclosures | Modular panels, doors, windows and silenced ventilation | Machinery noise containment |
| Specialist | Tuned, mine, metro and wind tunnel silencers | Project-specific duties |
Product pictures are illustrative configurations. The final design follows each customer’s process conditions and installation requirements.
In partnership with an Indian engineering company
We provide our industrial noise control solutions together with a partner company in India that specialises in the design and manufacture of industrial acoustic silencers and related products. Hela Innovations is your contact in Sri Lanka for enquiries, technical discussion, quotations, orders and after-sales follow-up. Our partner carries out the engineering design, fabrication, inspection and factory testing.
How an acoustic enclosure works
An acoustic enclosure contains the noise of compressors, blowers, generator sets and other machinery while keeping the equipment cool and easy to maintain.
- Block. Sealed, heavy steel panels stop sound escaping from the machine.
- Absorb. A mineral-wool lining behind perforated sheet removes sound energy inside the enclosure.
- Ventilate. Silenced inlet and outlet openings pass cooling air while attenuating noise.
The noise reduction target is set for each project, in dB(A) at a stated distance.
Acoustic enclosuresWhere noise control is needed in Sri Lanka
From factory floors to hotels and telecom sites, we help keep noisy equipment within the limits that apply at the site boundary.
Garment and textile plants
Air compressors, boilers and standby sets on dense factory floors.
Hotels, hospitals and offices
Standby diesel generators close to guests, patients and staff.
Tea, rubber and coconut mills
Blowers, dryers and fans running near estate villages.
Cement and ceramics
Large fans, mills and compressors in heavy-industry plants.
Ports and utilities
Pump stations, power packs and compressors at harbour and water sites.
Telecom and data sites
Gensets and cooling plant beside towers and urban buildings.
Noise limits in Sri Lanka come from the National Environmental (Noise Control) Regulations, enforced by the Central Environmental Authority. We size each silencer or enclosure to the limit that applies at your site boundary.
From design to a tested, documented product
Together with our partner company in India, we handle the complete project. Hela Innovations stays your single point of contact from the first enquiry to delivery.
- Engineering design. Acoustic and mechanical design to your duty, interfaces and noise target.
- Procurement. Selection and procurement of materials and consumables.
- Fabrication. Manufacture of the silencer, enclosure or perforated components.
- Third-party inspection. Independent inspection where your project requires it.
- Factory acceptance testing (FAT). The assembled product is tested before dispatch.
- Documentation and delivery. Complete project documentation, export documentation from India, and delivery to your site in Sri Lanka.
What we need from you
Send us as much of the following as you have. We will propose a design and a quotation, and ask for anything missing.
- Equipment and application (e.g. steam vent, compressor intake, generator exhaust)
- Fluid or gas, mass or volume flow, pressure and temperature
- Connection or duct sizes, orientation and available space
- Allowable pressure loss or backpressure
- Noise target in dB(A) at a stated distance, or the limit at your site boundary
- Existing noise measurements, drawings or photographs, if available
