Branch of business: Hydraulic consultation in the field of complex pipe system calculations.
We use and develop programs for steady state and transient flow.
The programs are used by us and owners of larger district heating (and cooling) systems.
We also work in fields as mining, black water, oil and process industry.
Examples of work
Hydraulic analyses of present or future district heating (and cooling) systems.
The systems are test driven in models that presents the hydraulic behavior of the systems in various points of operation. Problems as water hammers are solved as god as possible with our knowledge. More then half of the amount of district heating water in Sweden is in our computer models. About two thirds of the power in district cooling systems in Sweden is simulated by us.
Analyses of transient behavior (water hammer) in various systems. In best case we analyse and prevent damages, but sometimes it’s a matter of accident commission.
Education about district heating (and cooling) systems. In round figures a thousand people have had are courses. Most of them are operating staff but also consultants from companies as FVB, SWECO and ÅF have been educated.
