Power Noise Control

Steel or timber construction acoustic doors to suit a wide range of industrial applications for personnel and large oversize doors. Hinged, sliding or vertical lift door options can be selected to manage the combination of acoustic specification, with space and access needs.

Additional options include a wide selection of hardware and access control options, vision panels and automation. Acoustic louvres doors can also be provided where ventilation and airflow is required, while maintaining acoustic performance.

Steel, aluminium or timber construction acoustic windows are available either installed as part of an acoustic enclosure package, or as products to treat the internal or external areas of a power generation facility – perhaps a viewing window into a plant room or from a mezzanine floor into a larger CHP or cogeneration facility.

Product applications range from large glazed screens or partitions, eg. mezzanine floor to ground floor observation galleries, to primary and secondary glazing installations for external break-out noise control. Options are available for ATEX and bullet proof glass finishes for personnel protection from engine component or system failures.

With a range of durable steel absorptive panels we can provide acoustic treatment to increase absorption and reduce reverberation. This provides a lower noise level throughout an enclosed space within a power generation facility and is generally recognised to enhance personal effectiveness and comfort of operators.

Typically most installations are on approximately 60% coverage of vertical wall surfaces, but would be calculated based on specific installations. Melinex linings prevent contamination and the panels are robust in construction for cleaning and long-term durabilty.

Operable hanging hygienic ceiling baffles systems are also available. These demountable panels are stainless steel framed and available in finishes which suit either low contamination levels in dry/semi-wet environments or high contamination where plastic surface finishes allow for wet cleaning.

Power noise control projects typically have a limited overall pressure restriction that cannot be exceeded without detriment to the cooling of the equipment. Our acoustic louvres are specifically designed to for low pressure restrictions with weather protection at higher inlet velocities, than conventional architectural louvres.

Specific louvre designs can be tailored to provide enhanced protection against ingress of sand and dust – additionally filter systems can be specified. Secondary motorised, gravity-flap, fire & smoke damper and gas retention louvres can also be offered as standalone or an integrated parts of a total package solution.

Where industrial equipment is treated with an enclosed noise containment solution, it is vital to maintain correct ventilation whilst preventing noise breakout. Various systems can be offered, from simple acoustic duct-work and baffles to high performing splitter attenuator systems which can be “tuned” to counter specific dominant frequencies.

These are commonly specified with acoustic louvres, absorptive room linings, fire and gas retention dampers, exhaust gas silencers and acoustic and fire doors. They also form part of the packaged solution for both drop-over acoustic canopy and enclosure systems.

Exhaust gas silencers can be provided in mild steel / 304L and 316L grade stainless steel in sizes ranging from 50mm to 600mm bore to standard designs with bespoke designs beyond those sizes.

Single / twin and triple entry designs can be offered. Additionally, spark arrestor and catalytic converters systems can be incorporated and full SCR systems offered if needed.

Our acoustic enclosures range from large modular freestanding enclosures to smaller, close fitting enclosures or drop-over canopies. You can view typical larger enclosure solution build around a gas genset here.

Acoustic enclosures are designed and engineered depending upon the client’s requirement – from modular acoustic panel systems incorporating a range of standard panels, doors and windows, to one piece structural canopy enclosures with access panels, dropped over machinery or equipment.

Operational control systems, interlocks and safety controls can be incorporated with access doors and panels so the enclosure effectively forms part of any operational safety requirements. Further customisation is available, either by material, e.g. stainless steel finish, or personalisation via paint finish and branding.

Absorptive freestanding barriers are designed to your environmental installation, accounting for wind loading, long term external durability and structural support requirements. Prefabricated modular construction of single or dual sided absorptive barriers removes site welding requirements and provides rapid installation.

Reflective cladding panels are also available which compliment existing walls or barrier installations. These modular systems offer significant absorption, reducing reflected sound and overall environmental noise impact.
