Production introduction
The foinbo® dry fire sprinkler system is a specialized fire suppression solution designed for environments where temperatures regularly drop below freezing (below 40°F/4°C). Unlike traditional wet pipe sprinkler systems, which keep water constantly filled in the piping network, dry systems use pressurized air or nitrogen to prevent water from entering the pipes until a fire is detected. This makes them ideal for protecting unheated spaces such as cold storage warehouses, parking garages, loading docks, outdoor canopies, and northern climate facilities where freezing temperatures could cause pipe bursts and catastrophic water damage.
Dry fire sprinkler systems are widely used in:
- Cold Storage & Refrigeration Facilities
- Unheated Warehouses & Distribution Centers
- Parking Garages & Underground Structures
- Outdoor Infrastructure (Stadiums, Solar Farms, Amusement Parks)
- Historic Buildings (Where wet systems could damage delicate interiors)

FAQ
Q: What is a dry fire sprinkler system?
A: A fire suppression system that uses pressurized air/nitrogen instead of water in pipes to prevent freezing in cold environments.
Q: How does a dry sprinkler system differ from a wet system?
A:Wet systems keep water in pipes at all times, while dry systems only release water when a fire is detected.
Q: What is the typical air pressure range in a dry system?
A: 20–40 psi (pounds per square inch).
Q: How do dry sprinkler heads differ from wet heads?
A: Dry heads have extended lengths to reach into cold zones while keeping the valve chamber heated.
Q: What happens if a dry sprinkler head activates accidentally?
A: Only that head discharges water, minimizing damage.
