ADCA HOT CONDENSATE COOLERS HCC DESCRIPTION The HCC is a cooling device that allows the mixing of hot condensate with a lower temperature condensate, avoiding hammering. Condensate discharge from higher pressure lines (drip points, for instance) are often connected to low pressure condensate lines, with lower temperature. This sudden pressure drop will convert the sensible heat difference between the two fluid conditions into latent heat, generating flash steam. Flash steam has a much bigger volume than condensate and, when mixed with the cold condensate, it will cool suddenly, imploding and causing hammering (noise and vibration). The HCC avoids this phenomenon, since it slowly cools down the hot condensate which circulates inside a coil, surrounded by cold condensate which circulates according to the thermo-siphon physical laws. MAIN FEATURES Eliminates hammering. Corrosion-resistant internal coil. OPTIONS: Larger flow rates. Special tailored designs. Condensate discharge downstream of steam traps. AVAILABLE MODELS: Flanged EN 1092-1 PN 16 and PN 40. Flanged ASME B16.5 Class 150 or 300. Others on request. CONSTRUCTION: Carbon steel or stainless steel on request. INSTALLATION: Vertical installation. Hot condensate angle inlet and vertical outlet. Cold condensate bottom inlet and vertical outlet. LIMITING CONDITIONS HCC/S FLANGED PN 16 / CLASS 150 * ALLOW.

ADCA TYPICAL INSTALLATION OPERATION The steam trap hot condensate discharge from the steam line is connected to the top of the HCC coil (horizontal connection) which, in turn, is surrounded by cold condensate (Fig. 1), thus beginning to be cooled down while flowing to the top outlet (Fig.2), where it finally mixes with the colder condensate (Fig. 3). Flash steam bubbles that are formed during the process decrease, until they completely disappear, before the mentioned mixing process. The cold condensate is connected to the bottom of the HCC (Fig.1) and, in contact with the hot coil, is...
