The multitubular evaporators of the EMCH series are designed for applications in cooling processes of water and non-icing mixtures, as well as of any other liquid that is not corrosive to copper pipes. On the other hand, the EMCHI series is made entirely of AISI-316 or AISI-316 L stainless steel, with the exception of the exchange tubes, which are mounted in copper. Gases are incorporated into the equipment in the secondary circuit, which can be of any type, taking care to comply with pressure and corrosion limitations depending on the construction material. To do this, a thorough study of the application is carried out by the Intersam technical department. It should be noted that the entire range is capable of working with any refrigerant on the market if the limitations are applied in each case specific values ​​and if the appropriate power correction values ​​are adjusted, as well as those of the refrigerant pressure drop. Design The design is of the multitubular shell and tubes type, with a single pass through them. The fluid to be cooled circulates through the casing while the refrigerant circulates through the interior of the tubes. These tubes are smooth on the outside and corrugated on the inside. They also incorporate a fluted helical path thanks to which the transmission coefficient is increased, as well as the internal speed of the refrigerant gas. The tubes are clamped to the tube-holder flanges by mechanical expansion. The secondary circuit is provided with diaphragms that perform the function of supporting the tubes and, at the same time, force the circulation of the fluid thus increasing the effectiveness of the thermal exchange.
