At first glimpse, it is nothing but a giant vessel. However, if you thoroughly look at it, there is something, something that you never know before. This is what we call “Shell and Tube Condenser” by ITC.
The shell is constructed of ASTM-A-516 Grade 70 steel designed to handle 20 bars pressure. Moreover, ITC group has enhanced the shell’s durability to be more endured at high pressure resulting it to tolerate over 31 bars, which is hydraulic pressure, without damaging the steel.
The bundle of tubes manufactured from ASTM-A285 Grade C flange quality steel is attached inside the shell for water to pass through. This water serves as the key element of heat exchange.
When the two substances (water and gaseous ammonia) flow inside the condenser, heat exchange occurs. Ammonia gas turns to the liquid state while the water becomes warmer and exits the tube. Based on 40 oC condensing temperature, water can get warmer from 31 oC to 37 oC. Then, the condensation cycle (liquid ammonia) will repeat itself over and over again whilst the water re-circulates and moves through the cooling tower.
