This version of the multiple heat exchanger is particularly suitable for small baths or whenever the space vailable is limited. High outputs in the smallest space can be realized, on account of the good ratio between the exchange surface and space equired in connection with a thin-walled hose.

They can be designed in a U shape with one passage or in a square shape with several passages. The heat exchangers can be installed not only in the floor construction but also in the wall construction. The connecting pipework and type of connections are designed for the specific customer. The dimensions can be designed for the specific customer. The multiplesurface heat exchangers are manufactured from the PFA, ECTFE, PVDF and PP materials. Reinforcing frames are fabricated from PTFE for the special shapes made from PFA.
