District Cooling From Cooled Wastewater

• Use cooled wastewater as a heat sink in a district cooling water loop in Örebro, Sweden.
• For efficiency, the exchangers must have a close temperature approach and a low pressure drop.

Two Tranter SUPERCHANGER Plate And Frame Heat Exchangers installed in a dedicated heat exchanger station.

• The two exchangers remove 18 MW of heat from district cooling water.
• Only 1-bar (14-psi) pressure drop.
• Temperature approaches of less than 1°C (2°F), with “U” or “K “ values 3 to 6 times higher than shell and tube exchangers.
• High channel velocity and shear stress reduce maintenance requirements for the waste water channel.
