Dry systems are designed to not exceed what temperature for circulating water?

Dry systems are specifically designed to be used in environments where the risk of freezing is a concern, such as unheated buildings or outdoor installations. In these systems, the pipes are not filled with water; instead, they contain air or nitrogen under pressure. If the ambient temperature drops, the air or nitrogen remains in the pipes to prevent water from freezing.

The correct maximum temperature for circulating water in dry systems is 120°F. This is crucial because if the temperature rises above this threshold, there is a risk that water could be accidentally introduced into the system or that condensation could form, leading to potential freezing in the pipes during cold weather.

Keeping the temperature threshold at 120°F also helps maintain the integrity and reliability of materials used in dry systems, preventing premature wear or failure. Any temperatures above this limit can compromise the performance of the system and increase the risks associated with freezing temperatures.

In summary, 120°F is the upper limit for circulating water in dry systems to ensure safety and operational efficiency in colder environments.
