Örnalp & Unozon logotyp


Extreme demands are our everyday life

Our work is filled with challenges. We like that. It’s about finding smart solutions for demanding environments and often under tight deadlines. Our customers include companies in the defense, offshore, pulp and paper industry, chemical industry and the energy sector as well as nuclear power plants.

These are diverse industries that impose different and very specific demands on us as a supplier. Products such as marine environments that do not rust, products for tough conditions that must be light and products for factories with extreme cleanliness- and safety requirements. This calls for flexibility and capacity for rapid change, which has made our employees highly qualified specialists in various products and technologies.


An energy intensive manufacturing process

To manufacture paper requires large amounts of energy. A reduced energy consumption leads to significant cost savings and a better environmental profile.
Reduced costs and a cleaner environment

For a long time ViFlow have supplied heat exchangers, pressure vessels and process equipment to companies that produce pulp and paper. ViFlow´s products help customers to:

  • Increase the energy recovery
  • Reduce water consumption
  • Reduce the cost of water treatment
  • Reduce the cost of chemicals
  • Reduce maintenance

ViFlow offer the following products, among others, for customers in the pulp & paper industry:

  • Heat exchangers
  • Tanks and cisterns
  • Screw conveyors

ViFlow collaborate with a number of major companies in the pulp and paper industry – companies with high demands on quality and professional deliveries.


The energy issue – a challenge

One of the major challenges for both the present and the future is the energy issue. There is a great need to be able to use the existing energy as efficiently as possible, especially in industry, but also in society in general.

Heat recovery with heat exchangers

Transferring and recovering energy from one medium to another as efficiently as possible reduces environmental impact and increases the utilization rate of the available energy. ViFlow´s heat exchangers allows for the recovery of heat from, for example, waste water.

Products and Applications

ViFlow´s products in the energy sector consist mainly of heat exchangers but also of pressure vessels. We also offer installation of piping systems, specializing in high pressure steam pipes.

These products are used in the following applications:

  • Turbine condensers
  • Direct condensers
  • Heat exchangers for boiler and heating water
  • Oil preheaters
  • Oil coolers

ÖrnalpUnozon´s clients in the energy sector are for example nuclear power plants, energy producing companies, paper mills and suppliers of complete power plants as well as other businesses that want to recover heat and energy of various kinds.


The chemical industry is affected by rising energy prices and an increasingly extensive regulation.

Increased productivity and reduced environmental impact

ÖrnalpUnozon manufacture customized components that improve the customer’s production processes by taking advantage of the energy more effectively which results in increased productivity and a reduction of negative impacts on the environment.
