If a single chlorine cylinder is delivering 48 pounds per day and forming frost, what is the best solution?

When a single chlorine cylinder is delivering 48 pounds of chlorine per day and is forming frost, this indicates that the cylinder is being stressed and may be operating at or near its limit. The formation of frost occurs due to the rapid vaporization of chlorine when it's released from the cylinder, which can lower the temperature of the gas and lead to this phenomenon.

Adding another cylinder and feeding from both allows for a more balanced distribution of chlorine delivery. This approach ensures that neither cylinder is overloaded, reducing the risk of excessive frost formation. It enhances system reliability, as it enables continuous operation even if one cylinder needs maintenance or runs out of chlorine. Additionally, spreading the demand across two cylinders can improve safety and the overall efficiency of the chlorine feed system.

While options such as reducing the flow rate or switching to a different chemical might alleviate the frost issue temporarily or change the treatment method, they do not necessarily address the underlying problem of high demand on a single cylinder. Increasing the size of the cylinder does not solve the immediate issue either; rather, it may create a different set of challenges, such as handling and installation complications. Therefore, the most effective solution in this situation is to add another cylinder and feed from both to manage the chlorine feed rate more effectively
