Heat exchangers
For all applications
where even the best stainless steel doesn’t hold.
Principle of operation
FAFCO heat exchangers are designed to provide a large heat transfer area (0.43 m2/kWh of latent heat), and therefore a high exchange power.
The active part of the interchange consists of 6.5 mm diameter tubes extruded from a polypropylene-based polymer mixture. These ultra-stabilized plastic tubes are resistant to UV and all chemical attacks regularly encountered in the industry. They are assembled by a welding technology patented by FAFCO and incorporate a high-performance hydraulic distribution system designed by FAFCO. The heat-carrying fluid is distributed with great precision throughout the interchange, ensuring a highly efficient heat exchange and a homogeneous process of charging and dischargeing the accumulator.
This technology also has an extremely low load loss thanks to the large, efficient section of the tubing.

Manufacturing
The heat exchangers are made of 1.30 m wide modules. All these modules are assembled end-to-end by plastic welding using sleeves of the same material, to ensure perfect sealing to the interchange lines.
Depending on the project, the available space and the necessary refrigeration power, the size of the interchanges, the number of interchange modules per line and the number of lines is defined to match the customer’s needs.
These interchange lines are maintained by the internal structure of the accumulator. They are individually connected to the main arrival and start collectors of the glycolated water or water circuit of the accumulator by flexible armed rubber durites.
Minimum height: 1.55m standard, 1.00m if needed
Maximum height: 3.12m in steel bin, 4.20 m in concrete bin
Maximum interchange module per line: 8
Maximum number of lines: 38 to 80 depending on the type of bin
Exchanger technology FAFCO
A large exchange area
Low spacing between interchanges
Strong mechanical and chemical resistance thanks to the exclusive composition of FAFCO polymers
A vertical construction for a reinforced natural convection
A modular construction
A small amount of glycol needed
All our heat exchangers are tested at 20 bars with certificates
End-of-assembly pressure test at 6 bars for 12 hours
