Hydraulic cylinders and components, hydraulic systems, gas springs & shell and tube heat exchangers : Quiri

Liquid cooler

Industries concerned : 
Product concerned : Shell and tube heat exchangers
Liquid cooler : Shell and tube heat exchangers - Quiri
In a chemical process or an energy production process, a liquid can be caused to be cooled. If the fluid used for cooling is river water or sea water, multi-tube exchangers are particularly well suited because they allow the periodic cleaning which is essential to maintain the performance of the exchanger.

Thermal Specifics :


Quiri specialist in the design and manufacture of heat exchangers and boiler pressure vessels offers you a Liquid Cooler (Noria Cooler) which is a multitubular heat exchanger with fixed tube plates, type TEMA NEN.

The Noria cooling water circulating on the shell side is cooled by sea water circulating on the tube side. The use of sea water requires specific metallurgy and corrosion protection coating on the seawater box side.


This liquid cooler (Noria water) has been thermally designed, manufactured and installed by Quiri on behalf of an Electricity producer in Morocco.


For this project, Quiri also supplied four DN700 isolation valves on the seawater circuit side.
