1Remote Radiator

Radiator fans can be fitted internally or externally depending on requirements, they can be coupled to the discharge attenuator through a canvas connection preventing re-circulation and ensuring a positive air-flow through the enclosure.

2Door Canopy

From a practical perspective, having a doorway canopy overhead means you're protected from the elements as you enter/leave.

3Access Doors

Access Doors - Single, double or maintenance access doors. Fire & security rated available.

4Pipework (Gas)

Easy access to gas pipe connections and ports (for gas generators).

5Cable Box

Cable Link Box - A cable box provides an easy load connection point for SWA cables to be attached and converted into more flexibile Ho7 cable inside the container.

6Fire Alarm Beacon

Fire Alarm Beacon - Fire Alarm Beacons are an ideal way of giving a visual warning that the fire alarm system has been triggered. Our fire alarm beacons are manufactured to the highest quality conforming to British standards, ensuring you, your business and your team are quickly alerted in the event of fire.

7Lifting Eyes

Lifting eyes (occassionally referred to as lifting lugs). Designed to connect to the top, side or bottom of an acoustic enclosure so that the unit can be lifted by an overhead crane.

8Access Ladder

Provides easy access to the roof for maintenance operations.

9Exhaust/Silencer

Bespoke exhaust systems to guide exhaust gases away from the engine can be cylindrical or box-shaped based on project restrictions. Box-shaped exhausts can be recessed into the frame for reduced height. Both cylindrical and box exhausts can be place on the roof or side of an acoustic enclosure. Smaller engine-sized units can incorporate an exhaust inside the frame for a reduced overall footprint.

10Louvres

Multi-functional acoustic louvres allowing airflow throught the unit whilst simultaneously reducing noise created by the generator heard outside the enclosure. Louvres are available in a wide-range of standard modular sizes so performance requirements can be met.

11External Fuel Tanks

Bespoke external fuel tanks provide an increased operational run-time in a variety of shapes and sizes to counter spatial restrictions.

12External Lighting

Provides focused lighting to key areas of the container in low-light conditions.

13Emergency Stop

An emergency stop button wired in series with the control circuit of the generator. Pushing the emergency stop button will break the circuit of the genset and remove the power supply that keeps the circuit energised.

Bespoke Design

Our ability to manufacture fully bespoke enclosures provides us with opportunities to provide clients with complete noise control solutions where standard housings don't fulfil their entire specification.

We design, fabricate, paint, and fit-out all our acoustic solutions in-house at our large manufacturing facilities in Pontefract, UK and Hexham, Australia. This allows us to possess and expand on the expertise and flexibility required to accommodate enclosures of all shapes and sizes to suit even the most restrictive footprints (due to physical restrictions or planning permission) and airflow requirements, whilst upholding our strong commitments towards the safety of our employees and all parties involved in a project.

Whether you may need a prefabricated modular solution to be assembled on site, roof or side mounted inlet or outlet attenuators, or a low-profile recessed box-type silencer within the roof to reduce the overall height, our expert design team are on hand to find a solution that meets your requirements.

Acoustic Enclosures for Various Applications

Our bespoke acoustic enclosures are designed and manufactured specifically to reduce the environmental noise impacts of numerous types of equipment including:

Generator Sets

Pumps

Industrial Machinery

Quality Assured

Every single one of our acoustic housings is built within an ISO 9001 accredited quality management system, and manufactured using high quality steel & materials from highly reputable & respected suppliers, within a factory accredited to ISO 45001 for occupational health and safety, and ISO 14001 for our environmental management system. If required, the enclosures can be supplied with CE/UKCA marking to BS EN 1090 up to execution class 2 for steel structures as well as an NICEIC (electrical safety) certificate if required, and our installation electricians work to BS 7671 installation standards.

Noise Attenuation

As well as a need to develop more flexible spatial configurations, there is an ever-growing need to continually improve the noise reduction capabilities of generator housings. In the past, an acceptable noise level was around 80-85 dB(A) at a distance of 1 metre from the enclosure, but as noise pollution regulations, attenuation techniques, and sound absorbing materials have progressed in the last 30 years or so, a standard UK project is now approximately 10 dB(A) quieter than that, and often as low as 60 dB(A) at 1 metre when required - that's about as loud as a normal conversation between two people. With noise levels required on projects getting lower and lower, we have continued to meet client's requirements - no matter where in the world the final location of the equipment is - through innovation from our in-house design team that perform all the calculations required to develop new build methods to ensure our enclosures work at absorbing noise across all octave bands and meet even the quietest of specifications.

Bespoke Containerised Solutions

However, not all projects have a requirement for a complete bespoke solution manufactured from the ground up, open generators (mostly up to 1700 kVA) can be comfortably housed and suitably attenuated in a standard 10, 20, 30 or 40-foot ISO container. All the same options & extras that are available for our bespoke-built enclosures can also be fitted to a containerised solution. Enclosures built from ISO containers also come with their own range of benefits for your project:

Cost Effective

More cost efficient compared with complete bespoke-built housings.

Lead Times

Shorter overall project lead times, ensuring our commitment to every project being delivered on time, on-budget.

Logistics

Easier and more cost-efficient in comparison to load, transport & unload.

Acoustic & Ventilation Features

Specialist Acoustic Doors

Standard size & bespoke-built single & double acoustic doors with a wide range of lock, latch & handle mechanisms are available on all of our enclosures & containers in stainless steel, galvanised steel or aluminium material options. Our variety of doors can be coated with polyester powder to match adjoining louvres, and our louvred doors can be fitted with bird guards and insect meshes if required.

Acoustic Louvres

Our acoustic louvres are multi-purpose, permitting air to flow, whilst attenuating the noise from the generator heard outside the enclosure. Louvres are available in an array of standard modular sizes, meaning that a wide range of performance requirements can be met. By using our acoustic louvres, it overcomes architectural consistency issues, especially where space is limited.

Motorised & Gravity Louvres

Our gravity louvres are designed to counteract any equipment that may be sensitive to dust, by using automated pressure relief blades. Our motorised louvres automatically provide air that is accessible quickly from an intake after the generator has been started. One of the advantages of having motorised louvres is the ability to create an air-tight enclosure that impedes the progress of any potential fire.

Weather Louvres

In harmful environments where adverse weather can create a large amount of dust, our fixed-blade steel weather louvres can offer that extra necessary protection to the enclosed generator or equipment, allowing sufficient air flow (in both supply and return directions) for the machinery to function whilst protecting from dust, sand, rain, snow, hail and other extreme weather conditions.

Splitter Attenuators

Designed & manufactured to specification to achieve the required noise level reduction for industrial generator sets & other high noise source equipment/machinery. There are no restrictions for where an attenuator can be installed; and when space is a major factor, we can find a flexible solution for your precise requirements with a high quality, professional manufacture standard & installation.

Electrical Equipment & Enclosure Fit-Out

To meet the requirements of electrical contractors and aid installation on-site, external cable link boxes or special gland arrangements can be provided on both bespoke-built & containerised solutions to facilitate the connection of incoming armoured cables. All small light and power systems within an enclosure can be supplied & fitted by our highly qualified electrical team, working to BS 7671 installation standards. This includes: lighting with emergency battery backup, sockets and switches, distribution boards, heaters, fans, air conditioning, dehumidifiers, fire detection panels, and intruder alarms.

Electrical fit-out services can also be provided for the installation of outsourced or free-issued major components including: form 4 switchboards, distribution transformers and power conditioning equipment including associated containment protection systems and switchgear.

We can also provide generator enclosures and containers for the oil and gas market, and have a good understanding of the additional requirements that come with operating in these complex locations/environments.
