Case stories

Tap water with extreme hardness

Ringsjön is a lake in southern Sweden from which tap water is drawn. The very hard water (dH 11) imposes severe stress on the equipment used. After 4-6 years' operation, four SWEP heat exchangers used for heating the tap water were brought to SWEP’s laboratory for testing. 

Rank® Organic Rankine Cycle technology with applications in heat recovery solution

In a project involving ACCIONA and KEROS CERAMICA, RANK® has worked with SWEP to implement a heat recovery solution for electricity power generation.

Pure water cooling systems

In some applications, such as cooling of power electronics, ions are not desirable. Ions in the water may lead to short-circuit, or spark over in the electronic equipment.

Outokumpu cools machine shop using natural elements

Outokumpu – a world-leading company in custom-made products in coarse, special stainless steel (quarto) – has invested heavily in its rolling mill in Degerfors, Sweden. Cooling the machine shop to enable it to provide the best service to the rolling mill is of crucial importance.

Clean power when ORC system recovers waste heat

An affordable and sustainable supply of energy is the key to modern society as well as global economy.

High capacity industrial chillers no challenge for SWEP BHPEs

Industrial chillers come in a variety of sizes and models. Traditionally, shell & tube heat exchangers have been used for high capacity chillers, but SWEP BHPEs are changing that picture. Powerful yet small, they fit perfectly into most industrial applications.

Efficiently heating a national building in Beijing, China
