HIAK also offers services on consult basis in acoustics and design. These are based on more than 60 years of experience in many projects. The projects are spread in a wide area of branches, such as process industry, manufacturing industry, power generation and construction. Usually with comprehensive requirements involving, acoustic, abrasion resistance, air flow, pressure drop, temperatures, appearance and requirements from standards and building codes. The project has mostly resulted in delivery of a product, but today we deliver more and more technical specifications and drawings that the customer owns or have a license to use.
A few examples of customers for our services are, ABB, Siemens and Quintus.

What we can offer.
– Product development with focus on acoustic
– Developing of a concept
– Product evaluation in our acoustic laboratory
– Noise and vibration measurements
– Pre-studies
– Manufacturing documents
– Supervision of assembling
– Cost calculations
– Supplier assessment
– Assembling and installation
– Survey of installations

Benefits for you as customer
– Possibility to manufacturing with several suppliers on   manufacturing documents that you own.
– Optimized design for best performance regarding acoustic and   flow
– One contact with competence in acoustic, design,   manufacturing and quality requirements in many branches
– Design for efficient use of material, manufacturing and assembling
– Possibility for local manufacturing when you own the manufacturing documents
– Reduced transport and environment impact by local manufacturing
– Guaranteed acoustic performance
– Risk reduction when you own the specifications and are not reliant on a single supplier

In a world distinguished by a surplus of products and mass production, authentic skill and the capacity to understand customers’ wishes are crucial factors.

Our team of engineers features some of Sweden’s leading experts in industrial noise reduction solutions. Through our extensive experience in the field of noise reduction and acoustics we have built up a remarkable pool of knowledge. We work closely with you to identify your needs and circumstances.

We then apply a transparent process to identify a solution that ticks all the boxes. The earlier we apply our skills, the better we can assist you in finding efficient solutions.

You decide the scope of our commission. We provide everything from pure consultancy to turnkey installations.

We also offer ongoing checks and maintenance of our noise reduction solutions, to ensure that they keep on performing at an elevated level.

No two projects are alike, so we adapt and adjust our work process accordingly. However, even though each project demands a unique plan, projects generally feature a number of typical phases.

Power and Energy

HIAK supplies heat and power generators with products and solutions to deal with indoor and outdoor sources of noise. Distribution of electrical power is another area in which we supply specialist products and solutions to reduce the types of low-frequency noise that arise in transformers and reactors. Our range comprises products for incorporating in new units during the manufacturing phase, and for end users with existing facilities.

Manufacturing and process industries

Both manufacturing and process industries feature a great many sources of disruptive noise that demand various types of adapted noise reduction. We can take care of such issues with the least possible impact on production capacity. One important factor in the process industry is to optimise silencers so as to ensure the least possible pressure drop in relation to noise requirements, and thus maintain the maximum efficiency possible. Shielding operators from disruptive noise is crucial to occupational health and safety.

Marine and offshore

Offshore installations, distinguished by tough weather conditions are extremely high access requirements place extraordinary demands on both materials and design. Solutions for the marine and offshore industry have to be able to meet demands for low weight and high silencing, while simultaneously ensuring elevated performance from the units produced for this extreme environment.

HIAK is qualified according to the Achilles Joint Qualification System for suppliers to the oil industry in Norway and Denmark.

Engine testing installations

HIAK supplies soundproofed test facility solutions for everything from car and truck engines to complete test buildings for jet planes – and everything in between. In fact, HIAK actually began its business in the aeronautical industry. Ever since the first jet-powered Swedish fighter – the Saab 32 Lansen (Lance) – was launched in the 1950s, HIAK has been supplying noise-reducing products to air forces in a variety of countries.

Our customer base includes the air forces in Finland, Italy, Korea, Norway, Sweden, the UK and the US Air Force. Noise reduction within the aeronautical sector is ‘state of the art’ for industrial acoustics. If you can deal with the scream of a jet fighter firing up its after-burners, you can take care of pretty much anything in the field of noise reduction.
