Cross-flow tube heat exchangers [CFTHE] are designed for systems that require heat to be transferred between two gases without them coming into contact.
Compared to cross-flow plate heat exchangers, in the CFTHE, thermal energy is exchanged through bare tubes, usually made of stainless steel of various diameters and thicknesses depending on the required performance.
In the DAV GASY the tubes are coupled to tube plates by welding to ensure 100% tightness
The tubes are also easy to clean, either manually or with automatic systems.
DAV GASY is therefore the ideal solution for pre-heating air or other gases by recovering thermal energy from the exhaust fumes of boilers, engines, turbines and heavy industry in general.
By varying the length of the tubes and the number of passages through the tubes, an efficiency level of up to 80% can be achieved.

Compared to cross flow plate heat exchangers, in the CFTHE, heat energy is exchanged via smooth tubes, usually made of stainless steel of various diameters and thicknesses according to the required performance. In the DAV Gasy, the tubes are coupled to tube-sheet by rolling, which guarantee a seal level up to 99.9% and if necessary, can be welded to guarantee a 100% sealing.
Tubes are also easy to clean, either manually or by automatic systems. Therefore, DAV GASY is the ideal solution for preheating air by recovering thermal energy from exhausted gases from boilers, engines, turbines and heavy industry in general. By varying the pipes length and the number of passages across pipes, it is possible to achieve an efficiency level up to 80%.
The technical staff of DAV COIL is able to design heat exchangers according to customer needs, using sophisticated computerized calculation systems.
