We provide solutions to improve production and energy efficiency of industrial processes
20 years of experience in supporting clients goals
We are skilled to model, design, measure and implement equipment which help save energy, increase capacity or improve working conditions. The solutions we provide support our clients in reaching their targets and achieving their goals.
We are familiar, but not limited to, with drying section heat recovery and air systems, floatation dryers, machine room and other process ventilation, and drying kiln heat recovery systems.
In our references we have a wide range of modelling, design and deliveries mainly for Scandinavian pulp and paper industry.
We have a wide network which enables us to make projects from smaller modelling tasks up to large scale turnkey deliveries.
How the functioning of machine room ventilation can be evaluated?
Well-working machine room ventilation guarantees sufficient working conditions for the operators and for the process. Non-working ventilation can easily affect on product quality and cause problems for the production facilities...
Exhaust air flow from the dryer section is normally adjusted by maintaining constant water content in air flow. In some situations, exhaust air flow needs to be decreased thus causing decrease for the heat recovery process. Decreased humidity level decreases energy efficiency by means of lower heat recovery rate and higher specific heat consumption of the drying process.
Dryer exhaust air flow rate is one of the ways to maintain constant process conditions. However, due to the different boundary conditions set by process or machinery the flow rate can differ remarkably from the design point.
Computational fluid dynamics (CFD) is an efficient tool to estimate flow fields and their interaction with heat and humidity sources. What to take into the consideration when modeling complete machine room ventilation system?
