Often see vessels "dual stamped" of say 150 psig for -20 to 300 dF and then -50 to -21 dF at 60 psig. Concentrated ammonia is much colder than typical room temperature, which makes it an excellent choice for keeping things cool. Copper is not usually used in ammonia system because with the presence of water ammonia becomes ammonium hydroxide, the OH combined with Cu making cupric hydroxide of blue color. Pipes used for low temperature in Ammonia are ASTM A333 and for slightly higher temperatures A106 Or A53 can be used which is normal practice. Antimicrobial agent. Chloramine is preferred over chlorination for its ability to remain active in stagnant water pipes longer, reducing the risk of waterborne infections. While this is effective, it is also considered one of the most dangerous chemical compounds to store and is, therefore, unsuitable for domestic use.
