In which environment are dry pipe sprinkler systems typically installed?

Dry pipe sprinkler systems are specifically designed for use in environments where the temperature may drop below freezing, making them ideal for frozen environments. These systems address the risk of water in traditional wet pipe systems freezing and potentially causing pipe bursts, which could render the entire sprinkler system ineffective.

Dry pipe systems work by holding air under pressure in the pipes, and water is only released into the system when the sprinkler heads are activated by heat from a fire. This unique design prevents the water from sitting in the pipes and freezing.

In contrast, systems designed for heated or humid environments typically use wet pipe systems, where water is present in the pipes at all times, and standard environments are not specifically catered to the unique challenges of lower temperatures. Therefore, the choice of dry pipe systems is crucial for protecting facilities in climates where freezing temperatures are a concern.
