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

Industries concerned : 
Product concerned : Shell and tube heat exchangers
Preheater - Shell and tube heat exchangers - Quiri
Optimizing the thermal efficiency of an installation consists in optimally recovering the energy that would otherwise be lost (fatal heat). A water preheater makes it possible to recover the heat contained in the condensates before storage.

Thermal Specificities

  Quiri, as a specialist of heat exchangers, can provide you a water preheater. Device delivered in France in 2020 as part of the construction of a Waste Facility   The preheater supplied by Quiri is part of a batch of 3 heat exchangers: a water preheater, a vaporizer and a steam superheater. The Quiri thermal design heat exchanger preheats superheated water from condensates from an upstream turbine.
